HyperThreading question

[r00k]

In the instance that I have a 3.6 Ghz Xeon with Hyperthreading, and i run two instances of the folding client, how do i count that in terms of folding ghz.

does each work unit get calculated at 3.6 ghz, or what? I remember reading something about each one working at like 57.5 % of the ghz speed, but can't find it. if i were running only one folding client, it would be running at 3.6 ghz, right ?

Please help. This is important for my logs.

my vote is 3.6

specify please.

should i count each instance to be running at 3.6? so a total folding ghz as 7.2?

or should i count each instance as running 3.6 * (0.575) ?

3.6 total for the box is the way I've always counted.

3.6 total for the box is the way I've always counted.

that's because celerons only have one core.

3.6x2=7.2

that's because celerons only have one core.

3.6x2=7.2

It's a HT box, not a dual core box right r00k? HT does not count, never has counted, as double the GZh

For HT, most people assume about a 15% increase, so you might be able to safely say 3.6 x 1.15, or just go with 3.6 as marty said.

yes, single core, Hyper Threaded Xeon. Thanks for the help fellas
