Questions regarding multithreading

[freshspaceoctopus]

Hello,

I am currently running smartpca on a HPC using slurm.

smartpca version is 18140, and I use the following parameter file.

altnormstype: NO
numoutevec: 20
numoutlieriter: 0
numoutlierevec: 0
outliersigmathresh: 6.0
numthreads: 8
qtmode: 0
lsqproject: YES

I am not used to multithreading and running jobs in parallel.
I wanted to run threads in parallel, so I tried assigning 8 cpu per job, however when I login the computing nodes, only one processor is working per job, even though the log files say the job will work on 8 threads.

Is there another option to assign each thread to a cpu, or is it blocked somehow by my options?

Thank you in advance.
