Re: [hwloc-users] FW: Problem with hwloc_set_thread_cpubind() and pthread_barrier_wait() on new debianj
What the program does, is pick a pair of cpus (0,1) and run some tests, then pick the next pair (0,2) and do the tests again and so on. I didn't leave it run till the end because the output would pro- palby be quite big. I think the problem is on the kernel. I made a virtual machine with debian squeeze running kernel 2.6.32-5 and the binding doesn't work. When I run the same virtual machine with another kernel (2.6.30-2) and the program works fine. _ Your E-mail and More On-the-Go.

Re: [hwloc-users] hwloc with pthreads on windows
I'm using MinGW and Pthreads-w32. I've made the program to use HANDLE instead of pthreads but I'd prefer pthreads, so I'm asking if there is a way to make hwloc use pthreads instead of HANDLE > Date: Fri, 12 Mar 2010 15:47:07 +0100 > From: samuel.thiba...@inria.fr > To: hwloc-us...@open-mpi.org > Subject: Re: [hwloc-users] hwloc with pthreads on windows > > Αλέξανδρος Παπαδογιαννάκης, le Fri 12 Mar 2010 16:27:27 +0200, a écrit : > > Is there a way to use pthread_t instead of HANDLE in > > hwloc_set_thread_cpubind > > when running windows? > > Mmm, you mean when running cygwin? > > The problem is that to my knowledge, cygwin does not provide a pthread_t > -> HANDLE conversion function, which is needed to then call the > low-level windows functions. > > Samuel > ___ > hwloc-users mailing list > hwloc-us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/hwloc-users _ Hotmail: Powerful Free email with security by Microsoft. https://signup.live.com/signup.aspx?id=60969
