Can I use any program inside PelicanHPC that has SMP support and it would use all cores on my cluster nodes  or only programs that are specially built to use MPI?   Eg. using an SMP compiled mysql

 Thanks,

A threaded application will use all cores on a single node, but will not use cores on other nodes. For that, your app needs to use MPI or some other parallelization scheme.
