[mpich-discuss] mpirun on 1500~2000 cores

[bob ilgner]

Hi Dmitry,

What sort of cluster are you running the 1500-2000 cores on(example e1350)
and what is the nature of the application that you are running?

I did see Rajeev's response and noted the improced loading time with the
latest build.

Regards, bob
