windows and ubuntu linux are my OS

intent is to use them in the snow makecluster statement so I am not sure
what I need cores,cpus,real,virtual

basically the max amount of clusters i can create on my machine

2) if I have a workgroup on windows - can i detect cores/cpus on the network
using the detectcore
