New Computer for WCG

I am looking to buy a computer for the sole purpose of running WCG. Performance is my main goal within my budget (up to $2000). Electricity usage is second to performance.

What would be the best option for hardware?
-An i7 gaming computer.
-A server (Xeon)
-A pro workstation with Xeon
-Or something else I haven't listed here.

I have done some searching on the web in general and here on the WCG forums, however any information seems to be quite old.

Also does the OS play a major role in WGC performance? There are some old BOINC linux distros around that are built solely for BOINC however I don't know if these are still relevant.

Any help would be greatly appreciated.

Re: New Computer for WCG

Linux 64-bit is WAY BETTER than Windows 64-bit on certain sciences such as the ones running the Vina software (currently OET1). Around 50% faster.
FAAH2 is also a bit faster on Linux IIRC.

Regarding the hardware, I'm waiting to see how the new AMD Zen CPU's launching in Q4-16 will fare.

I don't know much about Intel offerings but I assume getting an i7 Sandy/Ivy bridge is better than the latest ones because they are only a few percentage points behind in performance when compared to the latest offerings. Intel has been focusing on power usage I think.

I'll let someone else answer that question ;)

Re: New Computer for WCG

"Around 50% faster."... a much more impressive statement v.v. AD Vina sciences [All of them], is "Twice as fast!" (it's higher in fact) as windows takes more than 2 times as long to process OET1 compared to Linux biggrin

The Haswell renditions are more energy efficient and coming down in price as they've been overtaken by Skylake, and since energy is the ever returning cost [with the accompanying reduction in heat generation, speak cooling needs], another important factor to consider [I'm so happy with me now over 2 years old 3770K ;].

Re: New Computer for WCG

Falconet-I read somewhere a leak that the zen based opterons will be 32 core chip and carry 8 lane ddr4 support. I am sure that will be at a price tag though. Either way, it sounds promising and I am looking forward to seeing if AMD can up their game to compete with Intel.

OP-I personally would steer clear of "gaming" computers such as alienware. You are paying a waaaaaay too high premium for a name (and garbage components, in my opinion). If you are somewhat technical, you can build a system to meet your needs and save some big coin. If you want to do gaming on the computer, a GTX980 or 970 would also double as an excellent GPU for if WCG ever get any other GPU capable projects in the future. Nvidia has a new technology called Pascal that from what I am reading, will blow away the current Maxwell architecture in the above referenced cards. Not sure when those will be out though, hoping by spring-summer 2016.

If you do decide to tackle building a system (its really not that hard, I taught myself about 14 years ago), Im sure there are plenty of people that would be happy to assist you in selecting the components that would fit your needs and budget.

Actually as far as the computer choice is concerned, I would have said get a nice i7 6700T (insisting on "T"!) on a good motherboard combined with 2 nice AMD 380 OC Nitro GPU coupled with lovely 4 gigs of DDR5 (quite as expensive as 2GB, so why go for less?) BUT since GPU-crunching isn't a topic here at WCG these days, you need to look around for other hardware... or other projects laughing On that PC, by definition your "gaming-PC" as you called it, I'd set up dualboot with Win10 for gaming and Linux to crunch over-night... (needs reboot though...) If you can afford, go with R9 Nano. My hint: For crunching, choose AMD, for gaming, go with Nvidia. Up to you what is the MOST important about what you want to do... better frame rates in games VS better crunching... cool

Now about OET1 itself: For that(!) project, I only go with dedicated 8-core Mediatek on Android (4.4.4 and 5.0). Result stats below show how well ARMs do in OET1 can be found here (It also include minicomputers running on various Linux-distributions):

http://wuprop.boinc-af.org/results/arm.py?pro...n=Outsmart+Ebola+Together

(The lower the number is, the better it is: The numbers represent the average hours(!) needed to crunch one OET1-unit is shown as the front number, obviously you'll get better results if your android device is dedicated and runs 24/7 without bloatware sitting in your memory. Also, if you disconnect from charger a lot, you'll find yourself on the slower end of the stat. So, if used as crunching device, expect results on the faster side though. Also, I need to consider that one of my devices has 8 cores each, according to my WCG-stats, I could claim about 8 OET1-units finished in 5-10hrs... depending on the Mediatek being used... I mostly use 2 major batches of units with different crunching power... and some random other Android devices from Samsung)
I can say that energy cost on those devices can (nearly) be completely disregarded (unless you plan running clusters)

My other x64-units crunch the other projects... like FAAH2, CEP2, MCM and UGM. Otherwise I'd pretty much feel like crunching on an x64 what could otherwise could be done on GPU... kinda inefficient! If one of those mentioned projects becomes available for GPU, like FAAH-VINA back in the "good old days", I'll take that project immediately off my "CPU-crunchers list". I'll go with whatever will be most efficient as far as electricity bill is concerned. Same feelings for me about OET1 on ARM/x64.

By the way, great Boinc-stats project, runs as non-CPU-intensive. Everybody should sign up there... wink

Re: New Computer for WCG

In general I'd say go for as many /cores/ as you can afford within your budget. Hyperthreading is nice too. Also there is a possibility to build more than one single system for $2000.

But if going for a single PC, I'd say get as many cores as possible. If you buy a 5960X you get 8 cores and 16 threads in parallel + a good Noctua NH-D15 cooler + Overclock + lots of RAM so that you can run a RAMDisk on for all those 16 threads (especially important for CEP2 with a HUGE RAMDisk since each such WU likes to have 1-1.6GB of RAM to itself).

5960X: $1000
Decent X99 socket 2011-3 motherboard: $300
Noctua NH-D15: $80
32GB RAM: $550
256GB SSD: $100
Some extra chassis fans etc: $50

Total: $2080
Or, if you don't plan to run a lot of CEP2 WUs on a RAMDisk, you can cut the RAM amount in half for a total of 16GB and remove roughly $225 and put some of them on a chassis if you need one.

Re: New Computer for WCG

Thank you evryone for your replies. Has anyone compared i7's to Xeon's for crunching? One could have multiple Xeon's on a single board as well, so not sure how this would stack up against a single i7.

It looks like some people here have multiple computers for crunching? Is it better to put all of my resources into one pc or multiple pc's (not sure if multple older and cheaper pc's would be better than a single "latest tech" pc).

Re: New Computer for WCG

well, about WCG, here a thing...to have most on WCG, you only need to have "most cores on CPU"...so:
1. use most modern MBO, for most modern CPU family...regardless if it's a AMD or INTEL...but I'd choose INTEL for mine, 'cause the have a higher Tjunc...so more reliable in temp. they are!
2. don't spend too much money on CPU...all you need is a proc with highest number of cores, so that you get most time on WCG! doesn't have to be fastest proc, just the most cores...& preferably with HT, so that you get 2x time of cores!
- also, you can always upgrade to faster CPU, in a year or two...postponing new config all together! wink
- p.s. some proc have intelHD with openCL enabled...so you can have 2x GPUs on your machine! & that rules of XEONs...
3. about GPU, you'd probably best stick with nVidia...it was 1st enabled here on WCG, so probably it will be again here on WCG! it also have a CUDA & openCL enabled, so it will get both of both worlds...
4. definitely use SSD
5. RAM, use slowest DDR3...'cause there not much performance issues in using fastest DDR3, while they get quite a pricey!

Hope this helps out!
wink

Re: New Computer for WCG

My philosophy... You can get more performance out of $2000 by purchasing multiple older Core i7-based systems from ebay than you can by building a single new powerful desktop. (You could get three i7-3770 systems for less than $1000, and that will give you 24 threads with a very good overall CPU benchmark total.)
