Re: [Question #681609]: hyper-threading and yade


Question #681609 on Yade changed:

    Status: Open => Answered

Robert Caulk proposed the following answer:
Hyperthreading *generally* does not improve or hinder performance on
single Linux workstations [1]. Some authors tested the effect of
hyperthreading on an OpenMP (shared memory) molecular dynamics code
(similar to Yade) and found that hyperthreading slightly improved
performance [2]. However, the same authors found that applications using
a distributed memory model (MPI) exhibted significantly degraded
performance when hyperthreading was active. So if you are running Yade
normally with OpenMP then I would say you won't see much of a difference
with hyperthreading on or off.
