Abstract

It is important to understand whether users want to use coprocessors as offload devices or as a separate compute node. In the latter case a user must be able to ssh from any other node in the cluster directly to a coprocessor, and find an environment (like cluster file system) similar or identical to a standard node. The Xeon Phi can be configured so that a user can run MPI on the coprocessors, only on the host processor (e.g. using the coprocessor in offload mode), or a mix of native coprocessor and/or host processor MPI codes.

The cluster model allows it very easily to port an MPI application and get it to run. ...
