[mpich-discuss] Regarding MPICH2-1.1.1p1 testing basing on open-mx

[Dave Goodell]

 From the names they do look like MPI one-sided tests, but I don't  
have a copy of the IMB benchmarks handy.  As I recall the  
ch3:nemesis:mx netmod does support the MPI one-sided APIs, although  
it's probably implemented in terms of two-sided operations under the  
hood.  Guillaume would know for sure.
