I'm in dispute with Dell. They offered, and I ordered, a Pentium D 3.0

They claim that MCC (multipe core capability), which the system has,
is better than hyperthreading.

My experience is that I can get 20+ SETI WUs a day with SetiDriver set
to 2 processes. If I set SetiDriver to 4 processes I get about 18 a
day.

Should I expect to get more than 20+ a day with hyperthreading?


I thought that HT was disabled on the Pentium Ds? IIRC only the XEON Ds will
have HT enabled.


I could be wrong...
