Dear All, I'm putting together a new Dell Xeon cluster running ROCKS 5.3 which uses CENTOS (6 I believe). This is currently ~20 dual quad-cores with roughly 16 GB of RAM each.
In any case, I wanted to inquire about hyperthreading. Does anyone have experience on similar machines with vs. without hyperthreading? The ROCKS users list suggests that hyperthreading ought always be off for HPC applications, which sounds overly simplistic to me, though I more or less follow the logic of this. So, has anyone done any benchmarking yet in a similar setting, and what thoughts do you have? I obviously can do some benchmarking myself as well but I thought I'd check in with the list first.
