[mvapich-discuss] Re: Supported compiler versions....

[Jonathan Perkins]

Mike:
Thanks for the note.

We don't formally keep track of minimum versions but will sometimes
add notes to our user guide if we find known bugs with recent versions
of compilers.  Mostly, we recommend users to run with newer versions
of compilers as this is what we tend to run our internal testing
against.

Hope this helps.

The problem only seems to occur in SLES11 and RHEL6, while SLES10 and RHEL5 are fine with pgi 9.0-4, and everything works with PGI 10.5. Looking at <sched.h>, it appears that the functions were replaced with new versions with slightly different names (__CPU_SET_S, etc...).
