#1850: Severe performance problem on Stampede -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: confirmed Priority: major | Milestone: Component: SimFactory | Version: development version Resolution: | Keywords: -------------------------+--------------------------------------------------
Comment (by hinder):
The problem is that all existing parameter files would need to be modified to include activation of SystemTopology, otherwise they will run very slowly. There is no warning about this; using the same parameter file that worked before, you just get really bad performance. People probably also have their own thornlists which don't activate SystemTopology. I think the best option would be to correct the affinity settings on stampede, so that they don't cause the code to be slow. Is it clear that they are wrong?
