A simple question on multithreading

[Alexander Dong Back Kim]

Hi all,

I'm having a fun with multi threading programming. My target machine
has 8 Intel Xeon CPUs. Working environment is Linux based and using g+
+. Boost library is being used for my fun.

My question is is there any possible way to bind a thread to a
specific CPU among 8 CPUs? If it is possible would you please let me
know where I have to start digging? +)

Cheers,
Alex

A linux group would be good place to start!

Check out the 'pthread_getaffinity_np()' and 'pthread_setaffinity_np()'
functions.
