Under utilization of computational resources in cluster

[CristianBezaBeza]

Hello,

I've been trying to run Orthograph in our cluster. I am requesting multiple cores; the resources are available in the cluster. However, when Orthograph is running, it does not use multiple threads. I've tried the config file on a lab server, and it can use multiple threads there. Do you have any suggestions and what could be happening?

Hi @CristianBezaBeza ,

please post the Orthograph config and the job script you use on your cluster. This will help me see what resources should actually be used by Orthograph.

The relevant settings are --num-threads on the Orthograph side and the number of threads requested from your resource manager (SLURM/SGE). It is also important to request that all CPUs be on a single compute node, otherwise Orthograph will not be able to use them all.
