Here on my server I have 2 threads per core: Thread(s) per core: 2. g. You might do this to potentially optimize the licensing costs of your software with an instance that has sufficient amounts of RAM for memory-intensive workloads but fewer CPU cores. core = Core() add the following line of code: self. Here are some advantages of the multicore processor: More transistor per choice; Shorter connections; Lower capacitance; A small circuit can work at fast speed; Difference between Core vs. 50GHz Stepping: 0 CPU MHz: 2494. The size of the thread pool and the host operating system impact performance and processor utilization. The total number of CPU(s): 32 (Since number of threads per core is 2) As @Durga mentioned , the nproc gives total number of CPUs. </p> <ul. However, for better performance, you may want to use a more powerful CPU, such as an AMD Ryzen Threadripper 3990X with 64 cores and 128 threads. 3. In the case of the server system listed above we expect to see 8 cores per socket and 16 threads per socket: $ sudo dmidecode -t 4 | grep -E 'Socket Designation|Count' Socket Designation: CPU1 Core Count: 8 Thread Count: 16 Socket Designation: CPU2 Core Count: 8 Thread Count: 16. Another way of requesting the same is to. The good news is, figuring that out is extremely easy in Windows 10. It will list how many cores you have and how many threads there are. Mac OS has been slower to migrate to SMT than Windows. Working: The thread. For CPU-bound threads the resource is usually one CPU core. Download to learn more. In the BIOS, navigate to the “CPU” or “Processor” section to see the number of threads. After some changes of my command, qemu still complained. This threshold cannot be overtaken because. A core is the physical hardware that works on the thread. Turns out that the acpi option on the boot line is the culprit. Threads improve the overall performance of a process which includes computational speed. Only if your application is highly unusual and spending 100% of its time using the CPU would limiting to one thread per core make sense. A single CPU core can have up-to 2 threads per core. Jul 20, 2012 at 18:50. You think in terms of threads per physical device. 3. py --auto-devices --chat --pre_layer 36 --model alpaca-30b-lora-int4 --wbits 4 --groupsize 128 --model_type llama --threads 16" So I am splitting between GPU and CPU. Does running. Typically, the number of threads the run truly concurrently is determined by the number of CPUs and CPU cores (including hyper threading) you have. A core is calculated as follows: Sum of (Total number of the core under each node) To calculate the total number of the core of each node = CPU SOCKET* CPU CORE . Multiple threads per core are maintained to. If you don't know how many you have, open Task Manager > click Performance > on the bottom logical processors = number of threads. SLURM_CPUS_PER_TASK Number of cpus requested per task. 1 Answer. To find the number of logical cores, as used in top, you should. I’ve run a simple test cuda program with <<<256,256>>> execution configuration on GTX1080 ( 20 SM, 128 core per SM) and Nsight shows that 160/256 blocks are “running”, which means 160256 threads are running on 12820 cuda cores. For example, if you double the number of. The hyper-threading allows a core to complete two tasks at once. So: 2 Intel Xeon, 20 physical cores each one, 2 threads each core, gives a total of 80. For your second example, the sbatch --ntasks 1 --cpus-per-task 24 [. so wasn't found, figure out where it is and set an environment variable called whatever you want with the directory where it is. The CPU count generated by the Informatica Identity Resolution (IIR) utility ssalinfo and used when checking the CPU count specified in the license key file, is based on the number of available processor threads, rather than the number of physical CPUs or even the number of available cores. This ratio describes how many virtual CPUs have to share a physical CPU. Download and save these images to a directory. Windows 10. And there's no 1 core 12 threads. So the only way to measure relative performance is with a. other cores can. 76. Up to **8 cores** per processor Up to **16 threads per processor** with Intel® Hyper-threading 2. Next, we have to consider the clock speed and work-per-clock advantage of the CPU core. In the meantime another thread does the same, gets blocked on a read and is put to sleep. Although more server CPU cores represent better performance, finding the right number of CPU cores depends on your specific IT environment and workloads. with 48 OpenMP threads per task # Disable CPU affinity which may degrade performance export MV2_ENABLE_AFFINITY=0 omp. 질문 Number of CPU threads per core 이건 뭔뜻이야? 느브리야야. The operating system treats it as 56 separate CPUs. 6 logical processors though. core. For most common tasks, a single core can support about 1. For example, if a CPU is dual core (i. For this application,. The more programs running on your computer, the more threads you will have active. NET 4. These tasks are usually software processes and threads that the OS schedules. , running 11 threads on 8 cores). The number of vCPU = CPU cores * threads per core . Going to have to try this guys settings as "out of the box" it wasn't viable. </p> <p dir=\"auto\">The default is fp16. Many CPUs have multiple cores. perf_event_paranoid=-1. The nproc command shows the number of processing units available on your Linux machine, run: $ nproc. If you don't see the Performance tab, click "More Details. if you give 2 cores to the vm as suggested above that does not mean 2 physical cores but could actually be a single core and both of its possible. Thus you will get a total of 24 CPUs on a single node. For reasons not yet determined, specifying acpi=off was causing the kernel to misinterpret the cpu topology, and what should have been 4 cores with hyperthreading capability was taken to mean 4 cpus as 2 cores using hyperthreading. In general, a processor can only work on one thread per core (CPUs with hyper threading can work on up to two threads per core). For CPU-bound threads the resource is usually one CPU core. That means you have 128 CUDA cores shared by a maximum of 2048 threads. having more cores is better for multi tasking on a cpu and for video encoding. If a given CPU has N = 4 cores, and M = 2 threads per core, then one thread in Java running an infinite loop generates a load of 1/(4*2) = ~12. Specifies the CPU options for the instance. Use the os. In this section, we’ll see how we can get the immediate thread count information of a process. It’s not possible to exceed the default number of vCPUs. 1 or 1. Here's what I did on Arch: ⎗Windows. The P-cores run at a 3. Hence, pass the --all option too: $ nproc --all. ) -. When you specify CPU options, you must specify both the number of CPU cores and threads per core. The no. g. Number of partitions to use is situational. Math Geek. Method #3: For Linux. ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. A lot more tensor cores. This means your processor can support 8 threads. Can someone. If you're trying to utilize all your cores optimally, Python threading won't help you with that. For multi-threaded tests, thread count of 2, 4, and 8 were tested. For the coding aspect, the number of execution resources is going to vary greatly depending on the program I am developing. For instance, a Power 8 processor with 12 cores can. The version 1 i posted here is not wrong, it just doesn't go in detail which might cause some people to have problems. Assuming you run your platform in hyper-thread mode (the default), the CPU has partial hardware support for 2 threads per core. Or even better than the ThreadPool, use . The OS recognizes each hardware thread as a different CPU. 4 GHz Intel Xeon® E5-2673 v3 (Haswell) processor, which can achieve clock speeds as high as 3. MySQL did not always scale as well as shown above. The default folder path for WebUI's built in Additional-Networks tab is X:\Stable-Diffusion-WebUI\models\lora, where models\lora needs to be created. Increasing number of threads decreases cpu performance. 1R1, the CPU allocations are displayed as a number range (for example, 4-7) instead of individual numbers (for example, 4,5,6,7). defval (python:int, optional) – The default value to be returned in case there is no replication information available. of threads to use (e. e. If you see a message saying that libcudart. Alternatively, you could use the --mem-per-cpu option. This can be useful for non-CPU-intensive workloads, where allowing a greater number of VMs to start can reduce hardware requirements (along with the associated benefits of easier management,. Most gaming cpus are hyper-threaded at 2 threads per core. Simply tap the Windows key (or click on the Start menu. I'm not certain why they do this, but my guess is to do with the size of the tasks that are given to run on the. The CPU, or processor, manages the fundamental computational work of the computer. However, this is not something you should care about at all. For instance, a Power 8 processor with 12 cores. . g. Each logical. For multi-threaded tests, thread count of 2, 4, and 8 were tested. Even with the specs of 2 cores and 4gb ram, it is a lot faster than my machine that has the exact same specs, except I don't know the speed of the core itself. Table 1: srun flags to support the multi-core/multi-threaded environment. @KGIII Thanks, I want the number of running threads per core. Thread(s) per core: 2 Core(s) per socket: 12 Socket(s): 4 With 4 CPU sockets available, you can install up to 12 cores per CPU, and each core has the ability to support two threads. No, it has 16 cores (subdivided into 32 threads, 2 per core). CPU usage was at constant 100%. 구독자 8248명 알림수신 108명 @Anon. A processor with 24 cores (yes, those exist), will have 48 threads. 001-0.

For a Mule runtime sitting on a 2 core CPU with 1 Gig machine or container,. i have tried stable diffusion with the automatic1111 webui on cpu only for the lols and must say I don't recommend it. Open Task Manager (press Ctrl+Shift+Esc) Select Performance tab Look for Cores and Logical Processors (Threads) Through Windows Device Manager: Open. If "one CPU" means a core (like often in high-performance computing), then it depends: a 1-way SMT core can execute only 1 thread at a time while a 2-way SMT core can execute 2 thread at a time. 001-0. To help you to gauge the efficiency, the following charts are available: Bar chart showing the number of CPU threads at each frequencyFor the benefit of our customers, here is a simple shell script that displays the number of physical processors, cores, virtual processors, cores per physical processor, number of hardware threads (vCPUs) per core and the virtual CPU mapping for all physical processors and cores on a Solaris system (SPARC or x86/x64). Specifies the CPU options for the instance. Please clarify, kindly bear if it's totally abusrd. The --cpus setting defines the number of CPUs a container may use. 16. So each CPU can address to processes at once giving you 16 logical processors. I’ve run a simple test cuda program with <<<256,256>>> execution configuration on GTX1080 ( 20 SM, 128 core per SM) and Nsight shows that 160/256 blocks are “running”, which means 160256 threads are running on 12820 cuda cores. cpus(); console. *). As this is a Intel CPU and Hyperthreading is activated, each core is seen by the Linux operation system as two "hyperthreaded" cores. The number of logical core per computing node is 2x20x2=80 which also matches with the number of "CPU" reported. e. Each core of a CPU is capable of running 1 instruction at a time, though Hypertheading allows a partial execution of two instructions simultaneously. threads_per_core = 2. AUTHORS top Cai Qian <[email protected]","path":". So adding more CPU cores or moving to a machine with faster cores will likely improve your performance. A single modern CPU typically has multiple cores. The short story is: most "dedicated" CPU instances across providers give you threads, with notable exceptions being the aforementioned t2d , as well as the ARM-powered VMs (e. The program itself is responsible for spawning the appropriate number of threads. CPUs are not physical CPUs. Let's say I have 8 cores with 2 threads per core. NET 2. Each CPU core can have two threads. No. When you change the instance type of an existing instance, the CPU options automatically change to the default CPU options for the new instance type. Because, in the specifications of Intel processors, they mention say if a processor has 4 cores simultaneous execution of 8 threads is possible. Whattteva. Ideally DW component executes on CPU_INTENSIVE which has a limited number of threads ( 2 thread per core). Modern hardware and OS combinations can easily handle thousands of them. , with OpenMP) per core. This file contains information about the CPUs on your system. Let’s finetune stable-diffusion-v1-5 with DreamBooth and LoRA with some 🐶 dog images. It might seem like the number of cycles is a ridiculous. 0005 - LR Scheduler: Cosine with restarts - LR warmup. so wasn't found, figure out where it is and set an environment variable called whatever you want with the directory where it is. The command to get the thread count of a process is: cat /proc/<pid>/status. Note that Hyperthreading does not enjoy SIMD on both threads. The number 8 below is the number of threads in the program but I need to know what is the number of threads my device can handle to run the program as fast as possible. . 3. Share:SPARC T5 and M5 processors [2, 3]—which are based on the highly successful SPARC S3 core first seen in the SPARC T4 processor—feature scalability exceeding 1,000 high-performance hardware threads (HWTs) for processing. Disable multithreading: by specifying 1 thread per core. Modifying the CPU options for an instance results in instance replacement. Total number of CPUs. The second thread adds about 30% performance. 7. so the result is correct as 204820 = 160256. 5. Another way to find the number of threads per core is to use the /proc/ cpuinfo file. CPU options are currently supported using the Amazon EC2 console, the AWS CLI, an AWS SDK, or the Amazon EC2 API. In my experiments, I found 5000 steps to be just about the right amount of training steps with the default 1e-5 Learning rate and cosine LR scheduler. NET 2. The formula is: 1 (processor) * 2 (core) * 2 (threads) = 4; so, I could create a virtual machine with maximum 4 vCPU. Incidentally, yes. pt fileYou can try running it now with accelerate launch --num_cpu_threads_per_process 12 lora_train_command_line. Here is what I see: 8. 0 framework that will actually determine the optimal number of threads to perform the tasks as efficiently as possible for you. CPU Thread Handling allows hosts to run VMs with a total number of processor cores greater than number of cores in the host. GOMAXPROCS () sets the number of (virtual) CPU cores that your program can use simultaneously. The number of active threads per core on AMD hardware is 4 to up to 10, depending on the kernel code (key word: occupancy). CPU(s): 56 Thread(s) per core: 2 Core(s) per socket: 14 Socket(s): 2. 1. Good CPUs for LLaMA are Intel Core i9-10900K, i7-12700K, or Ryzen 9 5900x. Seed is like an ID for randomized procedures. if the hyperthreading is enabled. You configure how the virtual CPUs are assigned in terms of cores and cores per socket. and setting defaults: threads_count = mono_cpu_count () * threads_per_cpu; threadpool->limit_worker_min = threadpool->limit_io_min = threads_count; So for mono looks like thread pool takes number of cores into account only for validating max number of threads: max number of threads cannot be less than. This includes the set of nodes in the. This is what you want to know. Those are the only lines of interest for this discussion. CPU is always requested as an absolute quantity, never as a relative quantity; 0. There are a few other commands we can use to get the processor information. com>, Karel Zak <kzak@redhat. Network Rank (Dimension)は128. i7 core can issue many more. Number of CPU cores: You can customize the number of CPU cores for the instance. The number of threads per CPU core during training. cpus () Returns an array of objects containing information about each CPU/core installed: model, speed (in MHz), and times (an object containing the number of milliseconds the CPU/core spent in: user, nice, sys, idle, and irq). Let’s dive right in. It’s not possible to exceed the default number of vCPUs. Number of CPU threads per core. 2. And some CPUs can run more than one parallel thread per CPU-core. The bottom line is that you can run 56 threads in parallel. The core count refers to the actual number of cores on the CPU die, whereas the thread count refers to the total number of concurrently running application. c. This means that with our example of 1000 cores,. Improve this answer. Here is what I see: 8. For CPU bound work the optimal number is 1 (per core). 000 BogoMIPS: 6984. 0 29492 29493 1 48. If you're trying to utilize all your cores optimally, Python threading won't help you with that. Simultaneous multi-threading, called Hyper-Threading by Intel, splits each physical core into two logical processors. The “/proc/cpuinfo” file is a virtual text file that contains information about CPUs (central processing units) on a computer. I know I have 20 threads. If a CPU has 8 cores with. I think you misunderstood the question. For example, high end ARM cores can dual or triple issue. 0. 0's CLR set the default ThreadPool to 25. If your CPU has 6 cores, 6 threads can run simultaneously but many threads are idle much of the time, waiting for I/O, say, and even if they're logically active the O/S can do time sharing between them. 147. For more information, see Optimizing CPU options in the Amazon EC2 documentation and Introducing Optimize CPUs for Amazon RDS for Oracle on the AWS website. Multithreading: The ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution concurrently, supported by the operating system [3]. cmd: @echo off for /f "tokens=*" %%f in ('wmic cpu get NumberOfCores /value ^| find "="') do set %%f. CPUs are constructed with many cores, not just one core per chip. of tasks to use per node. . If you don't see the Performance tab, click "More Details. 2 cores). In short: no guarantees how many threads will be run parallelly, but all of them will run concurrently. Threads refer to the virtual component which. g. Even servers in the 90s only managed one thread per CPU. get_ordinal (defval=0) [source] ¶IPEX is optimized for CPUs with AVX-512 or above, and functionally works for CPUs with only AVX2. 39. That is excellent from app-perspective. It selects a process in the queue. If you would want one thread per core you could use JULIA_EXCLUSIVE=1 or, for example, a tool like ThreadPinning. CPU Scheduler – Allows a single CPU to share system resources between multiple processes. 1 to 1. cores_per_package = 6 hw. Method 1: Check Number of CPU Cores Using Task Manager. But the question is, what exactly is a CPU? Why are we including threads in the above formula? Note: "theads" here is not. However, this highly depends on your code. Notation for CPUs : NAME (Cores/Threads, Single core frequency, Max Multi core frequency). Solution. A CPU has cores - it does not have threads. For more information, see CPU cores and threads per CPU core per instance type. </p> <h3 tabindex="-1" dir="auto"><a id="user-content-number-of-cpu-threads-per-core" class="anchor" aria-hidden="true" tabindex="-1" href="#number-of-cpu-threads-per. 2. Each vCPU is a thread of a CPU core, except for T2 instances and instances powered by AWS Graviton2 processors. Number of CPU threads per core; Seeds; Cache latents; Cache latents to disk; Learning rate: LR Scheduler: LR warmup; Optimizer; Optimizer extra arguments;. When you specify CPU options, you must specify both the number of CPU cores and threads per core. Sorted by: 0. the number of threads is not a multiple of number of cores (e. I have a machine which has 32 processor but i am really not sure how many threads are running. – Ben. A modern standard CPU for a standard PC usually have two or four cores. One caveat is that latency can increase for thread count greater than the number of physical cores due to cache thrashing. There is no maintained thread, core, or processor affinity (hence my prior question). It will list the total number of cores and the number of logical processors if that number is different. A comma-separated list or hyphen-separated range of CPUs a container can use, if. – eduncan911. 1 device where multiple cores would work on one thread. The Windows Taskmanager shows 4 cores, and 8 threads on. and having many apps opened. A thread is a stream of instructions. 4. Today, CPUs have been two and 18 cores, each of. --threads-per-core. The good news is, figuring that out is extremely easy in Windows 10. Each processor has 10 cores, each core being basically equivalent to a classic single-core CPU on its own. 0 GHz base/boost while the E-cores weigh in at 2. Table 13. The ACCRE cluster features 8-core and 12-core nodes, so a user can request up to 12 CPU cores per task. You can enter the BIOS by pressing a specific key (e. the <number> determines the amount of repeats your training script will do on that folder. 3. Actually, AIX does not have any cores. Here’s how it looks: (Threads x Cores) x Physical CPU = Number vCPU. Older POWER processors had only one thread per core/processor. CPU Thread Handling allows hosts to run VMs with a total number of processor cores greater than number of cores in the host. ForEach example taken from msdn, also there are other options look here also if there is alot of delays involved like reading a file or waiting for network traffic i would recommend using async functions (see example 2, also from msdn): The two below have smaller file sizes. In particular Intel's Hyperthreading often doesn't help with CPU-bound threads. LR Schedulerはcosine. Threads are the virtual components or codes, which divides the physical core of a CPU into virtual multiple cores. Often, this will be the number of. The core count refers to the actual number of cores on the CPU die, whereas the thread count refers to the total number of concurrently running application threads. Please clarify, kindly bear if it's totally abusrd. Otherwise you'd call it a 32 core CPU. core = Core() Under the line, self. You can view the efficiency and the metrics for each CPU thread. * and *. It is important to note that many of these flags are only meaningful if the processes have some affinity to specific CPUs and (optionally) memory. The CPU requirement for the GPQT (GPU) based model is lower that the one that are optimized for CPU. Each one of those cores is able to run 2 threads "simultaneously" (the Thread (s) per core line). Now if we launch 8 threads, we’re effectively doing 8/(4*2) = ~100% load. For example, an eight-core CPU appears as a single CPU with 8 cores and. Click Edit. This no longer seems to work for TrueNAS 12. Here's what I did on Arch: ⎗ Windows. Fig 7: Number of threads per process using /proc. 12 core is physical and 12 core is hyper threading. NET 2. #2. Your answer depends upon what environment you are executing in. --sockets-per-node=S: Number of sockets in a node to dedicate to a job (minimum)--cores-per-socket=C: Number of cores in a socket to dedicate to a job (minimum)--threads-per-core=T: Number of threads in a core to dedicate to a. Each core is its own processor. One way is to use the lscpu command. you request 32 core per socket, which is per physical CPU. ) Traditional ( heavyweight ) processes have a single thread of control - There is one program counter, and one sequence of instructions that can be carried out at any given time. When a task is executed on the CPU, it is divided into multiple threads that can be executed simultaneously on different cores or virtual cores, depending on the number of logical processors available. Number of CPU threads per core: 2; Cache latents and cache latents to disk – checkmark both. 5 Workflow Included. It corresponds to the following improvements in NovelAI's article (For Aspect Ratio Bucketing, I referred to NovelAI's code, but the final code is all original). Good CPUs for LLaMA are Intel Core i9-10900K, i7-12700K, or Ryzen 9 5900x. The "Virtual CPUs per core 32" section applies to the total number of vCPUs of ALL VMs combined per physical CPU core. 2. The number of threads that can exist on the system is limited by the available memory (each thread requires a stack and a structure used by the OS to manage the thread), and possibly there is a limitation how many. having python process with two busy threads on dual core CPU: $ ps -p 29492 -L -o pid,tid,psr,pcpu PID TID PSR %CPU 29492 29492 1 0. Maven 3. Each program on your computer is made up of one or more threads. The server’s capacity is 32 CPU cores, so when every request to the website on average uses 0. --threads-batch THREADS_BATCH : Number of threads to use for batches/prompt processing. 4. LoRA type: Standard Instance prompt: [any unique name will do] Class Prompt: person Mixed Precision fp16 - Save Precision fp16 CPU Threads per core: 2 Cache Latent 18 images * 10 repeats * 10 epochs ÷ 1 Batch Size = 1800 steps (I try to keep steps between 1800-2000) Network Rank (Dimension): 16 Network Alpha: 8 Number of CPU threads per core: 2; Cache latents and cache latents to disk – checkmark both. The second indicates the LoRA file name, the third indicates the LoRA strength. You might use std::thread::hardware_concurrency () as a hint. Simultaneous multi-threading, called Hyper-Threading by Intel, splits each physical core into two logical processors. Then you would be able to run 2x4x2=16 processes (without oversubscription of resources, of courses). I think you misunderstood the question. 0 GHz base/boost while the E-cores weigh in at 2. Share. To produce the same image my 2070 super can do in 15 seconds, on CPU only took 10 minutes. Allow additional threads, and one can be using the CPU while another is waiting for external data. What this means, is that when you migrate a VM over to Hyper-V on WS2019, you need to update the VM configuration and change some settings, or it will only use a single hardware thread per core, exhibiting the behavior you see above. In this way we can achieve the advantage of both 1:1 and N:1 threading models. Yes, it’s possible to check the number of CPU threads on your computer through the BIOS. Multiprocessing: The use of two or more CPUs within a single computer system [4][5]. You should use number of hardware threads, many modern CPUs have 2 hardware threads per core. The second parameter (B) is the number of threads per block, which can also be expressed 3-dimensionally. Currently, the i5-750 is the only i5 available, and it is a quad core without SMT. (Number of the core of a node is = number of sockets * number of cores) Now do it for all nodes and add them. Replace 16 with the number of threads your CPU has, if you have more or less. CPU Threading Modes and. Without any additional or special hardware, this is equal to the core count. More information F-16 VM CPU refer to this link. Virtual cores get mapped to operating system threads. For more , refer this answer, to get interpretation of /proc/cpuinfo refer thisFor most common tasks, a single core can support about 1. Each individual device has different optimal DOP's (magnetic disk = 1, SSD at least 4, network much higher). – To change the number of threads per core on an existing VM, use the following Google Cloud console procedure: In the Google Cloud console, go to the VM instances page. regnodes. Parameters Core Threads; Definition: CPU cores mean the actual hardware component. . For the purposes of Docker and Linux distros CPUs are defined as: CPUs = Threads per core X cores per socket X sockets. Under the System section, you will see the number of cores listed next to the Processor field. In the case of the server system listed above we expect to see 8 cores per socket and 16 threads per socket: $ sudo dmidecode -t 4 | grep -E 'Socket Designation|Count' Socket Designation: CPU1 Core Count: 8 Thread Count: 16 Socket Designation: CPU2 Core Count: 8 Thread Count: 16. If you use CPU overcommitment in the configuration of your VMware virtual machines, keep in mind these values: 1:1 to 3:1 – There should be no problems in running VMs. Here's what I did on Arch: ⎗ “MultiO” => Threads = Number of logical cores * 2: overcommited threads, bad situation (O=overcommit). The number of cores is typically listed on the CPU’s packaging or in the product description. In computing parlance, this can be seen as a system with 16 CPUs that lists CPUs by CPU number.
