For a short while I got a chance to run dnetc on a dual processor AMD  
Opteron 6128 machine (2x8 physical cores). The OS is FreeBSD 10.1 amd64.

In dnetc.ini I have:


During startup, the client log says that 16 crunchers are started.  
However, top shows that only one dnetc process is running (even top -P  
confirms this). On an older machine with two physical cores, the same  
kind of setup shows two dnetc processes.

Looks like all 16 crunchers were stared on one core?

dnetc v2.9110-519-CTR-11040103 for FreeBSD (FreeBSD 10.1-RELEASE).
