Hi all, I ran into an issue with hyper threading on OSX this morning, and after a discussion with Brad some questions were posed that seem better suited for a group discussion.
Currently numCores (at least on linux) includes the count for hyper-threading. This introduces some ambiguity in the meaning of ‘here.numCores’ (physical vs. logical), and raises some questions: - What should numCores represent? - Should we separate the notion of physical cores and the amount of parallelism in hardware (new variable/name)? - What does this mean for dataParTasksPerLocale? Hopefully this gets the ball rolling. -Ben ------------------------------------------------------------------------------ Is your legacy SCM system holding you back?
