HPC workloads normally at least won't benefit and probably take a hit from HT on Xeon-ish hardware at least. It's normally turned off on HPC compute nodes (perhaps in software so the resource manager can enable per-job if necessary). There are exceptions, particularly with KNC and, perhaps, KNL. The situation is likely different for POWER, but I don't have experience of it. |
