[mvapich-discuss] Building mvapich2

[Jonathan Perkins]

Hello.  Are you trying to build MVAPICH2 in shared memory only mode or
do you intend to use your ethernet fabric for inter-node
communication?

If you intend to use ethernet you will need to select one of the
tcp/ip channels at configure time.
I suggest adding the following `--with-device=ch3:nemesis'

If you intend to use shared memory only, you can build using our
default channel but you are required to have the infiniband devel
packages installed for the build to complete successfully.

You can find more information in our userguide:
