Hi Paul,
Thanks for your speedy response! In that case, I assume 1GB/core is the memory allocation? Is it helpful to increase that?

Hi Mitch,
In our experience, -openmp 8 gives faster recons than -openmp 4, but the gains after -openmp 8 diminish quickly and aren't worth it.

If I have 100s of subjects to recon and have access to an HPC with both GPU and CPU options what is the recommended flags to maximize speed performance? Is … -parallel -openmp 4 … still the best approach? And if so, is 2GB memory/core best (keeping it 8GB memory/subject) or is there some better arrangement?
Best, Mitch
