Subject: Missing option to print the number of cores (excluding hyperthreads)

Date: Fri, 21 May 2010 10:41:20 +0200

Package: coreutils
Version: 8.4-1
Severity: wishlist
File: /usr/bin/nproc

Hi,

linux is aware of cores and hyperthreads. It would be nice if one
could ask nproc the number of actual cores as opposed to threads for
the purpose of running cache intensive jobs where hyperthreading only
slows things down.
