I am working on a tool to allow students to self-evaluate their programming assignment's performance. In particular, the program they're writing is multi-threaded and I have no direct way of influe...

I need to set the affinity (thread to core, eg: 1st thread to 1st core) before creating a thread. Something like KMP_AFFINITY in OpenMP. Is it possible? edit: I try in this way, but dont' work :/ ...

I want to bind the threads in my code to each physical core. With GCC I have successfully done this using sched_setaffinity so I no longer have to set export OMP_PROC_BIND=true. I want to do the sa...

I'm developing an application in c++. One of the components of the application uses Matlab (via the Matlab engine) for data processing. At the same time, a data acquisition system is streaming data...

I would like to know if it is possible to identify physical processor (core) used by thread with specific thread-id? For example, I have a multithreaded application that has two (2) threads (thre...

I am using the taskset tool to set CPU affinity for one of my programs. How do I set the affinity on a single CPU only - since I was not sure about this, so I was doing this: taskset -c 2-2 tests/...

I'm trying to set core affinity (Thread #1 goes on first core, Thread #2 goes on second core, ...) while using std::thread in C++ 11. I've already searched around various topics and on the interne...

In linux where I work mostly, we use a technique called CPU isolation, that effectively locks a process on to a processor and also prevents the processor from running anything else. Our kernel guys...

I'm trying to set the CPU affinity of threads on Linux. I'd like to know which one of the following approaches is recommended: Get thread id using pthread_self() Set CPU affinity using pthre...

I have a quad core system with third party application that once in a while spins several processes (always the same executable but several instances of it) and takes 100% of CPU time. I also have ...

(Posting this with answer because I couldn't find a full explanation of how to do this anywhere, so I thought it might have some value for someone) How can I set the processor affinity of a partic...

I have noticed that several of my multi-threaded calculations run faster if I disable hyper-threading in the BIOS. I have also learnt that I can programmatically disable the (logical) CPU:s by mod...

This question asks about ensuring two processes run on the same CPU. Using sched_setaffinity I can limit a process to a number of logical CPUs, but how can I ensure that these are mapped to specifi...

Possible Duplicate: how to set CPU affinity of a particular pthread? Is there a way in Linux to disable one core for all processes except one process? I would like to have one core reserve...

I have 4 threads, and I am trying to set thread 1 to run on CPU 1, thread 2 on CPU 2, etc. When I run my code below, the affinity masks are returning the correct values, but, however, when I do a s...

I have a server process that forks many child processes. The server process has affinity to a CPU core, but I don't want that affinity to be inherited by child process (rather OS should handle wher...

I have written a program that captures and displays video from three video cards. For every frame I spawn a thread that compresses the frame to Jpeg and then puts it in queue for writing to disk. I...

I am having a hard time finding information about how to set cpu affinity for linux kernel (with all of its loaded modules), NOT for a specific process. This is because I want the kernel to ...

In Linux there is a sched_setaffinity() function defined in sched.h, but I can't seem to find anything like that in Mac OS X 10.6 pthreads implementation... If it is not possible to set affinity, w...

Lets say there are two processors on a machine. Thread A is running on P1 and Thread B is running on P2. Thread A calls Sleep(10000); Is it possible that when Thread A starts executing again, it ...

How can the CPU affinity of a process be set in kernel module? In user mode there is a syscall sched_setaffinity, but I am looking for the kernel mode equivalent. In the Linux kernel code, there i...

I have a program written in C#, I am using VSTS 2008 + .Net 3.5 + Windows Vista Enterprise x86 to develop a Windows Forms application. My current computer is dual-core CPU, I want to set CPU affin...

I've got a dual processor machine and I would like to launch an executable via a batch file on both processors. For example: (1) Launch Notepad.exe on Processor 1, and (2) Simultaneously, Notepad...
