[mvapich-discuss] Checking MVAPICH2 for IB

[Ali Eker]

Hello,

I built mvapich2-2.3.1 on our x86_64 cluster (CentOS 7) which have
Mellanox`s IB and ethernet options. I did not specify any configuration
flags.

My app compiles and runs fine but I cannot be sure about which network
option is used. I am checking strace output and I cannot see any call to
Mellanox or IB libraries.

How can I be sure the IB is actually used ? If it is not, how can I
configure mvapich2 to use it ?

Thank you,

Ali
