[mvapich-discuss] Latest mvapich problems with PCI-Expess InfiniPath

[Sayantan Sur]

Hello Andrey,

Since the announcement of MVAPICH-0.9.8-rc0, we have made several 
changes to our codebase. Today, we have made a MVAPICH-0.9.8-rc1 tarball 
(and SVN tag) available. We'd be glad if you gave this new release 
candidate a shot to see if your problems go away.

Thanks,
Sayantan.
