It's defaulting to 12 threads so that tells me that it does take multiple CPU's
also of note, I've got this running on numerous dual 16-core opteron setups and it takes those like a champ... 900H/s
Each CPU can run 12 threads (6 cores hypertthreaded) so it appears you are only using one CPU. With both CPUs it should default
to 24.
interesting.... am I missing something when I compile i wonder? I figured it would automatically pick up the other CPU?
