I am trying to run raxml (https://sco.h-its.org/exelixis/web/software/raxml/hands_on.html) on HPC cluster using multiple cpus using a pbs script below, but for some reason it is only using one cpu and is very slow. I have selected 60 cpus with
-T 60, but the process only seems to use a single cpu. Is there anything I am missing here? Thanks for your help in advance.
