[mvapich-discuss] Setting default mpicc/mpif77 CFLAGS, FCFLAGS

[Novosielski, Ryan]

Is this true of 2.0.1 as well? The documentation is different for that section. The sum-total on 2.0.1 of information on Slurm is:

4.3.2  Using SLURM

If you’d like to use slurm to launch your MPI programs please use the following configure options.

$ ./configure --with-pm=no --with-pmi=slurm

…which I didn’t try without trying to set flags.
