[mpich-discuss] A few inconveniences with MPICH 3.3 build

[Balaji, Pavan]

Martin,

For the slurm question, no you don't need to configure with slurm to get the nodelist.  You only need it if you want to use srun directly.  The recommended option is to use mpiexec directly (like you normally would).  mpiexec will internally lose srun anyway, and it'll automatically detect the nodes that you allocated in slurm (e.g., through salloc).

Adding slurm to configure allows you to use slurm's PMI, which is just internal MPICH-speak.  You probably won't need to care about that.
