[mvapich-discuss] OpenFabrics

[Di Domenico, Michael]

I just built an OpenFabric v1.0 cluster of two machines on a pair of
Quad Proc Itanium servers.  Both machines have Mellanox HCA's with
Mellanox firmware.

 

I also downloaded the OSU version of mvapich from the website instead of
using the bundled version.

 

Everything compiles fine, simple cpi tests work okay, netpipe runs okay,
so I'm pretty sure my fabric is okay.

 

But when I try to run osu_latency, osu_bw, or osu_bibw tests, it just
stalls.

 

How can I determine where the program is stalling?

 

Thanks
