The next thing you need is to select one or more, but more requires manual editing of settings that I don’t cover here machine to be the subnet manager for your infiniband network. Once you have the proper kernel space and user space hardware drivers loaded, you are almost ready to start rudimentary testing. It should, however, be the fastest MPI we ship.

The mvapich2 implementation is an MPI2 compliant version of mvapich and is identical in most respects except that it does not support the ppc64 architecture at the moment. Then, these drivers will be automatically loaded into the kernel for you if you enable linux infiniband openidb service. infiniban
The init script is not enabled by default, users need to run linux infiniband –level openibd on” in order to enable the service. Interfaces are listed by their linux infiniband in the roughly ascending order, so the interface at the end of each section should be the fastest. The openib package name is historical and problematic to change in the middle of a product lifetime.
