Hi Norm,

Thanks for using MVAPICH2.

As you may know, mvapich2 is a software package based on mpich2 from
ANL. Thus, you are looking at the building instructions for mpich2,
not mvapich2.

Yeah, this is ib code provided by ANL. I believe you are using vapi. So
please using our build script: make.mvapich2.vapi

Please change MTHOME in make.mvapich2.vapi to your ib directory, eg,
/usr/mellanox/. Then type: ./make.mvapich2.vapi. It should build mvapich2
as you need.

Also, we have prepared a user guide online. You can refer it for further
instructions:

Thanks.
