[mvapich-discuss] mvapich2-1.6 problems with np ~ >= 1000

[Jonathan Perkins]

Can you tell us some details about your setup?  Which version of
mvapich2 are you using?  How many nodes are you launching this on?
Can you try running an osu benchmark such as osu_bcast using this same
setup?

You can get the osu benchmarks from
http://mvapich.cse.ohio-state.edu/benchmarks/osu-micro-benchmarks-3.3.tar.gz.
