Hi all, firstly i would like to apologize if I posted this thread in the wrong place, i looked around and couldn't find a more appropriate place.
----------------------------------------I am a student who has received funding to build a computer whose sole purpose will be to crunch for BOINC. I will be receiving 3000USD and i want to make the most of it. The proposed build i have designed can be found here . It is highly centered around the processor as it will be crunching mainly for WCG. The CPU has been chosen because of its price in comparison to the amount of cores it has, 12 with hyper-threading. This is with the assumption that the more cores the more tasks can be completed at once, leading it to be a smart choice for its price. The motherboard is the only one i could find with the appropriate socket for the CPU, LGA2011-3. With 3000USD i can buy 3 units. The rest of the components are simply a necessity. My questions are, Should the amount of cores per CPU be a priority? Should AMD processors be considered or does hyper-threading trump them? are there any more affordable or powerful builds that i should consider, with maximum performance in mind?

If you want to save money on the O/S and are savy with Linux just go that route. Free download and runs some task (namely FAAH VINA units) faster than windows.
----------------------------------------Yes CPU should be a priority if using for crunching WCG at the moment. The one you picked is a good one. Keep in mind with only 1 stick of RAM that you are planning on putting in each system, you're only using 1 of the 4 channels of possible memory which may lead to a bit of a performance loss. I know DDR4 is not cheap but just be aware of that. AMD processors are cost effective but perform in accordance with their price which is not that well. Having said that I do have a dual socket G34 system 2 X 12 cores (Opteron 6180) system and am pretty happy with it for the price that I paid for the used parts. Good luck with your builds.  |

Thanks for answering, your reply got me thinking about motherboards with dual sockets. I created another build this time with the e5-2620 v2 cpu.
here is the build i made. Before I buy the parts, can i ask if you could look over the build? here is a spreadsheet with the components. that would help me a lot |

If I were you, I'll wait until October, when admins will probably announce that MCM will start using GPUs. In that case, maybe you should purchase a good GPU too.

Where have you heard of GPU computing being enabled for MCM? In October?
----------------------------------------Alejandro Guariguata: The hardware to choose will depend a lot on if you have power efficiency and/or single/multiple machine restrictions? But yes, the number fo cores will be most important, since the benefit of parallelism will quickly beat frequency at WCG.

Maybe there's an october update expected which might reveal something?
If it was a private communication, then it should have stayed private. Seen some things being posted from emails, but did the person from project and wcg who replied to the member give permission to pass this on publicly? The only thing said on the public side was that gpu route was being evaluated for mcm. That said, we're closing in on 1 year running on mcm1 with 1 year to go, on known work set. With an 18-20 fold speed up, maybe already too late... done in a month. Not that it bothers me it being done in a month, but then wcg only has 1 general availability project, not counting the coming ugm1. As some say, we just crunch on. There are so many other worthy boinc projects that can use an extra gear.  |

As you will recall, when HCC was in that situation, they just found more work to do. I am all for GPUs, not only to help the project along, but also to save on power. (If they want to do AVX2 on the CPUs, I have the Haswell cores for that too.) |

Hi Alejandro Guariguata and welcome to the forum!
----------------------------------------I reviewed your spreadsheet and have a few suggestions. 5) BOINC work is sometimes RAM demanding so I recommend you consider a minimum of 8 GB per box. 7) A 500 watt PSU does not allow headroom and you will not be able to power a GPU upgrade. Recommend 750 watt minimum. 9) SSD is overkill for BOINC and 120 GB may limit the number of tasks you can run. Suggest you consider a HDD of 1TB. Good luck in your build. edit: correct typo - tks Sgt. Joe  [Edit 1 times, last edit by foxfire at Sep 29, 2014 10:55:19 PM] |

Actually 120 GB should be more than sufficient space, but the use of an SSD will only minimally increase the processing speed of the WU's, especially CEP2 because of its high I/O demands, but the gain even there will be marginal at best.
