Subject: Re: [OMPI users] Compiling Open MPI 1.7.4 using PGI 14.2 and Mellanox HCOLL enabled

Hi Jeff, Hi Ake,

removing --with-slurm and keeping --with-hcoll seems to work. The error disappears at compile time, I have not yet tried to run a job. I can copy config.log and the make.log is needed.

Cheers,
F
