[mvapich-discuss] mvapich2 problem

[wei huang]

Hi Chandan,

Thanks for using mvapich2.

I wonder if you have started mpd daemons on your running nodes? Different
from mvapich (mpich1 based), mvapich2 (mpich2 based) requires using mpd to
start your jobs.

For detailed instruction, please visit our online manual at:

http://nowlab.cse.ohio-state.edu/projects/mpi-iba/download-mvapich2/mvapich2_user_guide.html#x1-150005

Please let us know if you have further questions.

Thanks.

Regards,
Wei Huang
