Intel ATOM based systems

Hi everyone,
got a simple question. What about dual core intel Atom 330 cpu? Is it powerful enough? What I have in mind is cheap system with very low power drain (<40W), which would run 360d/yr. SSD drive, 2gigs of ram, linux... What do you think? Does it worth even thinking about that:)? I know such system cant compete with C2D like CPUs or even Quad cores. But my criteria are power drain (lowest possible) and price. Thanks for every opinion!

Re: Intel ATOM based systems

Hi Predseda,
I think so. Read some post days ago about a user that are using ATOM processor on laptops and so on.

Good crunch for you and would be great if you share with us yours experiences with ATOM processor on Linux, after some time of crunch. Thank you in advance. coffee

Re: Intel ATOM based systems

I'm already waiting until this dual core ATOM is widespread on the market. But <40W seems to me a little high in your mentioned configuration, when I compare this with 2 three years old laptops of the shelf under full load:
IBM single core 1.7 GHz: 32.16W
Fujitsu Siemes single core 1.5 GHz: 25.85W

I am interested. And of course there is CADENCE's option to run it from the USB.

10/25/08 		0:000:16:05:15 		311 		2

This means 23,9 WCG points/hour. This seems to me very low granted credits. The average for the WCG projects is about 77 points/hour.
The in my former post mentioned laptops got (in another not extremely high granting project) an average of 98 resp. 84 points/hour.

Re: Intel ATOM based systems

Yeah right. Got avg. 67/h on my laptop. But my client is running approximately 12 hours/day. Atom machine would run 24 hours/day. Still it seems unable to reach the output of my laptop (daily). So thanks a lot for CADENCE`s numbers. Still I cant decide crying

To Crystal Pellet: 40W is top of the whole system under full throttle. Included the loss of efficiency of the power supply. I would use only 80+ certified one.

Re: Intel ATOM based systems

CADENCE ATOM 330 machine seems to be configured as a 4 CPU machine. http://boincstats.com/stats/host_graph.php?pr=wcg&id=739060
That means twice runtime on a dual core.
That explains the long runtime and low credit/hour, because one thread is using only 800MHz. So if you use the two cores 100% you should take the credit/hour times 4 ??

Re: Intel ATOM based systems

Well, I dont know exatly if boinc uses the benefits of hyperthreading (implementation of two threads on one core), but I suppose that it is possible to switch that off in bios. Then both system and client should see only two cores instead of four and use them 100% on each task. Wouldnt turning off hyperthreading be a step back? You know, if you look at the longtime picture. Are you sure, that multithreading on one core causes that two tasks use exactly half of the cores potential? Magic... Got it! laughing

Re: Intel ATOM based systems

I run WCG on my server which is a 2.6GHz P4 HT and I run 2 WUs at the same time with not a lot of lost processing time.

Re: Intel ATOM based systems

Yes, my Atom 330 has HyperThreading enabled. You basically get around 45 - 50 points per hour on this machine. If you are interested, I can do some more detailed analysis into how many credits you can get for each WCG project (some projects may feel better on this CPU than others). I may also disable HT to see what's the change there (but I would expect that the number of credits/h will go down).

It seems like Atom 330 fares better with projects that use x86_64 architecture extensions. I personally switched it to ABC@HOME since it's getting much more credits there. But if you are only crunching WCG, then I'm not sure if ATOM is a good choice (at least not until some WCG projects start using x86_64 extensions).
