Hi, Tim.

Thanks for confirming this. This will be available with the next release of MVAPICH2.

Thx,
Hari.

Thanks Hari,

That patch worked just fine. No more errors while compiling with default settings.

Hi, Tim.

Please accept my sincere apologies for the delay in getting back to you on this. Can you please try the patch below and see if it works for you?

Hello,
I have found that a basic build of mvapich2 with the PGI compilers fails when building mvapich2 2.3.1. To reproduce

./configure --with-device=ch3:psm --prefix=/share/apps/mvapich2/2.3.1/pgi/19.1

With CC/CXX/FC/F77 set correctly for the PGI compilers.

The error comes when compiling mpispawn.c

make V=1

If I replace -O2 with -O it goes past the error without problem.  This is true for the PGI 19.1 and 19.5

I have not dug too deeply into this.. I'm a sys-admin not a developer 😊

Thanks
