[openib-general] oops with ipath and mvapich (branch 1.0)

Hello Ralph,


Thanks for sharing the info.

Hmm ... I'm wondering if you really meant to say that WITH -debug flag
you get "Connection Refused" and WITHOUT -debug, you get only the header
followed by a hang?

I ask this because -debug forwards X from the remote node to your X
server, so you can debug different processes in xterms. In case your SSH
is not configured to forward X, then you may get that "Connection
Refused" message.

Another quick question. Did you use -DADAPTIVE_RDMA_FAST_PATH instead of
-DMEMORY_SCALE in make.mvapich.gen2 as per Matt's suggestion (earlier in
this email thread)? I'm wondering if you could give that a shot and
verify if that works on your platform?

Thanks,
Sayantan.
