F@H ?

Will an HT enabled P4 act as two CPU's while crunching? Can I sent up two instances of the CLI or will it be faster to just use one?

Read this: http://forum.folding-community.org/viewtopic.php?t=3165&highlight=hyper+threading Basically you need to run 2 clients in order to make effective use of your CPU!

and if you go here http://forum.folding-community.org/search.php and type in "hyper threading" you should get some useful hits.

It looks it will be about a week before you overtake me, less if this is a new machine you are adding! Good luck 🙂

Well, it looks like alnitak answered you question. Which is a good thing, since I don't know anything about HT in P4s. 😱

uh... shouldn't HT help most when 2 completely different tasks are being done? So... choose a project completely different to F@H (the CPU parts being used)... I think that should give both projects as much as possible out of the CPU.

That has been my understanding as well.

Nooooo.. you are going to bust the cache, for example, if you run F@H and SETI.

I guess I should have used the "search" button.
