I assume that you mean that you have a "question"
about running on an infinband network, rather than
being "skeptical" about whether you can run a job on an
Whatever application you want to use the Infiniband
connection has to have Infiniband support compiled in.
Typically, the application is MPI. If so, you will need to
install MPI (usually openmpi) with Infiniband support.
For openmpi compiled this way, communication uses IB if it is
available, otherwise it will use IP (Ethernet) communication.
