[mpich-discuss] pgf90-Error-Unknown switch: -pthread

[James Long]

Hi Gus,
     CC=gcc and F77=FC=pgf90 (with FFLAGS=FCFLAGS=noswitcherror) also fails. Removing the flag from the /usr/lib/libpmi.la lets it compile, so am testing that now.

The "srun: error: slurm_send_recv_rc_msg_only_one: Connection timed out" was a firewall issue.

Thanks,

Jim
