[Pvfs2-users] MX help

[Bradley Settlemyer]

I tried to, though I may have failed.

  $ ./configure --prefix=/home/bradles/software/pvfs-mx-2.8.1
--without-openssl --with-mx=/opt/mx --without-bmi-tcp

The performance has mainly been bi-stable with moderate number of
clients (8 nodes, 8 procs per node) small numbers of I/O nodes (1-10),
I think as I increase the number of I/O nodes (and the number of
clients), the number of clos-hops will become more uniform and
performance will stabilize.  I've got a hundred or so more
benchmarking jobs in the queue, so I can report back soon hopefully.

Cheers,
Brad
