Efficient cruncher build

Hello all. I crunch only WCG and therefore CPU only projects Every year I spec out (and sometime even build) a CPU only cruncher. My goals are: best points per watt, long term stability, longevity, and the least amount of attention. My concept of operation is: build, load projects, stability test. Then, set in an out of the way place without keyboard monitor or mouse; communicate once per week via usb LAN adapter using TeamViewer. I've been fairly successful in this getting appx 5000 points per day(BOINC) on about 80-90 watts. These also make great space heaters in the winter :grinning: I've tried open air, multiboard custom builds but cat't match a cheap case for cost and convenience. I'm due a new build and I would welcome comments/suggestions from this group. See my proposed build at https://secure.newegg.com/Wishlist/MyWishlistDetail?ID=3657655.

Re: Efficient cruncher build

Looks like it takes a day or so before a public wish list is posted from newegg. Here's the link https://secure.newegg.com/Wishlist/PublicWishlistDetail?ID=3657655. Should work within 24 Hrs.

Re: Efficient cruncher build

No hyperthreading on that CPU? Only 4 cores for $800, hmm. You can get 16 threaded machines for nearly the same price.

+1

Also, you might take computer without OS & purchase it here:
- https://keyforwindows.co.uk/ms-office-pack
- https://purchasewindowsproductkey.co.uk/ms-office-pack
That would cost you about $100 less, but will give you option to go to lower (or higher) end i7 with HT option (which will double the days here on WCG).
cool

Or, just forget about that & go with some of the trusted older workstations from Dell, Lenovo or similar company: https://forums.envato.com/t/modern-consumer-b...monster-workstation/77021

Re: Efficient cruncher build

If you are only using it for crunching, the best processor available, a decent amount of ram, and a high quality power supply are all you really need to look at. A cheap motherboard, a flavor of linux, and a cheap case would finish it up.

If you are ok with android systems, the odroid xu4 is a fun little toy. Currently WCG only supports android on ARM processors, so I run android on mine. It is an octo core that runs the big.LITTLE architecture. 4 cores run at I think 2GHz, and the other 4 run at 1.2GHz. Can't remember the specs off the top of my head but I think thats right. It can run off a micro SD card, or an emmc. Very small and efficient. I would recommend an aftermarket heatsink and fan though. The stock one is loud and inefficient. I mounted mine in a small box with a lid, and have a 120MM pusher fan and a 120MM exhaust fan creating a wind tunnel over it. The CPU fan rarely even turns on even at 100% 24/7.

Re: Efficient cruncher build

I also use a Odroid XU4 and a XU4Q (passive cooling) for crunching. Each generates in average 11000 points per day each for about 150W consumption.

However, on the maintenance side would like to point out that:
- could not find a remote tool
- at least on the Android version I've found for the XU4 the wifi would not automatically reconnect in case of disconnect. Only a restart of the XU4 will work.

Re: Efficient cruncher build

Thanks to you guys I spent about 4 hours researching Odroid. Fascinating. smile
couple of questons for aaabaab

1) I assume the 11000 points you mentioned are for both units and WCG not BOINC
2) Is the 150W for both
3) did you pick you nickname to rise to the top in sorts laughing

@B2I

1. The 11000 points are indeed WCG points and are produced by each unit - please see below the stats for one of the units

Re: Efficient cruncher build

Try the Lenovo M710 Tiny machine. I can get it for just over $510 with latest i7 8-core, 4GB RAM, 500GB drive, and Windows10. 65watts of power. And this thing is TINY!! I have the same i7 in an Lenovo tower and for the price, it cranks! My tower generates 40,000-50,000 points per day on WCG doing 2 Cancer projects...so that's about 8-9 times what you are looking to accomplish and since the Tiny versions run the same i7 chip at 65watts, that seems pretty darn good.

I believe I can share with your my corporate discount plan (about 30% off any Lenovo website price). Let me know (I guess there is no way to private message me on this forum).

I thought about custom builds over the years but I found it just doesn't seem worth saving $42 at the end of the day to have to do all the research (hours or days), build it, install the OS, etc. when I can just order a mass-market quality machine all set to go in 7 minutes drinking my soda and spend 4 minutes clicking OK setting up Windows when it arrives. Not to mention that Projects will come and go and video card crunching will come and go, etc. Although super technical, I just don't see the need or even point of squeezing every last cpu cycle out to save such minimal money. My time and sanity is worth it...and I also don't want to deal with Newegg in a battle to replace my <insert your hardware piece here> and they tell me to call the manufacturer. :) Spend the $25+ at Lenovo or Dell and get the Next Business Day Replacement and be done with it or save the $25 and get the normal 4-5 day Replacement.

What I have always dreamed of is that someone on Boinc/WCG would step up and create some kind of non-profit that simply sells hardware to Boinc/WCG users for crunching. That person buys in bulk and Dell/Lenovo/whoever gives a nice discount to help these worthy causes.

I would start such a program but I just don't have the time to run the show. But again, I think I can provide my corporate discount. Personally, I want to buy 10 or 20 of these m710 machines...it's my way of donating to Cancer research instead of checks to 1000 different cancer orgs. I'll let this site know if I buy a boatload.

If someone has something deeply negative about the M710 with the i7 chip, honestly, I'd like to hear it so I can better spend my money.
