Hello patches and welcome to the the forum.
HPF2 is rather resource intensive. You may do better with clean water on that machine.

HCC (Help conquer Cancer) and HCMD2 (Help Cure Muscular Dystrophy and the mentioned C4CW have smaller footprints. HPF2 falls in the heavier class as do FightAIDS and Help Fight Childhood Cancer.


No need to switch HT off... simply set the client to

"On Multi Processor system, use at most 50% of the processors"

and only 1 tasks will run at the time. The OS will take care what resource to use and you might even be able to watch video without need to stop crunching :D

I'm glad to see this thread, as I'd been thinking about what were the best projects to run on my slow Atom-based mini-desktop. It has dual core Atom 330 and 2 GB memory, and runs under Ubuntu Linux 10.04. With hyperthreading on, it happily runs 4 C4CW WUs at a time, or any combination of 4 WUs from C4CW, HCC, and HCMD2.

I actually am steering away from HCMD2 on it now, however, as it never can complete a WU before the 6-hr cap, and I think that ends up making more crunching time for the "child" WUs.

It has successfully run the big footprint projects, as long as I babysit to make sure it doesn't try to do more than one big one at a time. It has even run some CEP2 WUs, but I don't do them on it anymore either because it doesn't get very far before the 12-hr cap.

It does great with DDDT2 C-type units, but I don't try to get those because they come interspersed with A-type and B-type, which are too lengthy for this machine.

I think I did a timing experiment running C4CW with HT on and with HT off. The WUs took less than twice as long with HT on, so I figured that was the more efficient way to go. C4CW was my best bet for that test since its WUs are of such consistent length.

I can't recall this machine ever having an error or invalid WU. And since it's low-power and doesn't generate too much heat, I could run it 24/7 all summer.

So I say more power to you, patches, for crunching with Atoms -- and C4CW and HCC are great choices of projects for them. But do finish those HPF2 units you're running -- they'll almost certainly finish and validate and make their contribution!

Since my laptop is slowly going... completely worn mouse pad, shaky power connector, battery no longer charging... will be looking soon for a replacement. What has an duo hyperthreaded CPU... I3 / i5 xxx ? an I5 750m or is the 520M maybe a better choice... lower power and comparible speed... maybe one that has this turbo function?

Sorry for an ignorant question, but would you say more about what is the advantage of 32 nm parts? Thanks!

And thanks for the informative links!
