Well, in the first place, it depends an the Angle Range (AR), how much credits were claimed/granted (and also on the needed MFLOPs, etc.). So you can't really compare them to each other...

But yes, HT does its benefit on number crunching. As I can remember from the past days, one of my machine did a work unit in about 3 hours without HT, but did 2 work units in about 4.5 hours with HT enabled (given the approx. same AR, on non-enhanced, non-optimized WU/client).

Maybe it's the Pipeline or the L2 cache.. anyway, it "works" a little faster.

hi all,

i just celebrating the double of my credits in only 7 days since i started again to participate on the project's.

by the way, i saw that the computer running with active HT got more credits in this week...

Recent average credit Total
250.36 3,197.21 <- no HT
266.22 3,427.08 <- active HT

Booth of them started to crunch at the same time without any further stops.
