However, many CPUs consist of multiple cores and threads, so the traditional 1:1 mapping is no longer useful. A more useful approach is to set ncpus to equal one of the following: The number of processors Cores—the number of cores (per processor) * the number of processors (this is the ncpus default setting) Threads—the number of threads (per core) * the number of cores (per processor) * the number of processors Hyper-threading:
