is STAR MPI-capable?

[Vasily A.]

When I submit a task to our computational cluster and request multiple cores, sometimes it happens that allocated cores belong to different nodes, unless I explicitly request a single node. I recently learned that when the software is not specially designed for parallel computing, it will not work as expected on multiple nodes. I know that STAR is multithreaded - but is it MPI-capable?

Hi Vasily,

STAR is not MPI-capable, it's only multithreaded on a shared memory system (i.e. typically single-node). You would need to request all cores on a single node.
