Whats the general opinion of using HT? It seems to process a single wu faster when limited to 1 processor but does two at a time (obviously :-) ) when set to 2 processors, although a bit slower.

I use HT whenever possible, I also use Windows. People that use Linux
have reported large slowdowns when crunching while HT is enabled. In
Windows it seems that with HT enabled you can crunch 2 units in about
125% of the time it takes to crunch a single unit. Giving you a time
savings.

Hence, with HT enabled and running two WUs simultaneously, you get more WUs processed per day even though each individual WU takes slightly longer.

I believe that the HT feature of Intel CPUs is accommodated in the 2.6 SMP kernels. Try a recent Linux distro and give it a try.


Welcome to Boinc,

Happy crunchin',
