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

[Mike Heinz]

Jonathan,

Is there any info on the minimum supported compiler versions for mvapich2? I didn't find anything in the release notes.

We're running into an issue where on certain versions of Linux, mvapich2 fails to build with PGI 9.0-4, but builds correctly with a newer version of PGI.  The problem appears to be some macros:

/var/tmp/QLogic-mvapich2/OFEDRPMS/BUILD/mvapich2-1.7/lib/libmpich.so: undefined reference to `__CPU_SET'
/var/tmp/QLogic-mvapich2/OFEDRPMS/BUILD/mvapich2-1.7/lib/libmpich.so: undefined reference to `__CPU_ZERO'
/var/tmp/QLogic-mvapich2/OFEDRPMS/BUILD/mvapich2-1.7/lib/libmpich.so: undefined reference to `__CPU_ISSET'

This appears to be a gcc/distro/pgi problem rather than an mvapich2. 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...).

Again, this isn't a complaint, just wondering if you've defined minimum release levels for compiler support.
