The new Quadro's are scheduled to be released this October. (Raytracing and rendering)
Check out these specs:  http://www.digitaleng.news/de/editors-pick-nvidia-quadro-gpus/

More details:  http://www.anandtech.com/show/10516/nvidia-announces-quadro-pascal-family-quadro-p6000-p5000

The new cards now incorporate 16 and 24 GB ECC memory.  :o

MFM: Kind of a bulky way of doing it (info from 2009), but to just slap some machines together that you have laying around, it's a pretty good article.

IPMI is another reason to use a SuperMicro MoBo for the Head Node, it's baked right into an embedded chip. There have been some hellacious exploits against IPMI, so make sure you look into that and run a firewall between your public and private nets if you'll be running your build with an internet connection. If it's a single purpose machine, and you're the only one with physical access and no internet connection, then you shouldn't have to worry. IPMI makes administrating the nodes very simple.

This thread reminds me of being back in college hanging out with my hacker buddies in the computer department. Whenever we all hung out the conversation would eventually get around to computer spec talk. A more philosophical friend of mine mused during one of those conversations that in our father's generation they all sat around and talked about how fast their cars were. In ours we talk about how fast our computers are. In a generation we went from the speed of physical travel to the speed of mental travel being the most important thing. Well, his words have never really stop echoing in my mind because they've only seemed to get more true as time goes by.

Hi Doc. :)  I'll bet a generation or two before that it was the fastest horse, best breeding, stamina, and rough trail traversal. ;)  But I get your point.

W_A_N, the systems you're familiar with get an honorable mention in the following article. https://www.quora.com/Are-there-any-motherboards-designed-for-high-performance-computing


MFM, I found a good one for you. I'd still recommend server / enterprise level hardware if you are doing a production build rather than a hobby build  - especially the motherboard.      http://www.logicalincrements.com/articles/videoediting/

Check the comments on these pages too. There are additional tricks listed.

For example, I like this guy, and he is correct if you use the XEONs he mentions. ( If you are considering this, you're not the first as X58 Chipset components seem to be drying up.)

" Ryan 19 months ago

Consider going back in time to the x56.. Processors with the lga1366/socket Asus server mother board. 1. You can practically blow any I7 out of the water with two x5680s for $300 and you'll have more pcie slots to play with. Having DDR4 would be nice, but it's not a practical option, and probably won't be, for a while for budget workstations.  "             

    ^^^^        To avoid confusion, the lga 1366 motherboard socket uses an X58 chipset. His mention of x56.. refers to the intel XEON CPU designation e.g.  x5670, x5680, x5690, etc..  x=power draw (L would be low power) the 56 is a hexa-core (12 w/ hyperthreading) if it were 55 it would be a quad-core (8 w/ HT) The 55's have an 8MB cache whereas the 56 has 12. (Level-3)
Another tip on XEONs, stick with the ones that end in a 0. The specs are different with the interim numbered chips. Ex. Choice between x5674 and an x5670. pick x5670 unless they are the same price and check to see if the additional power draw is worth the minimal computational gain. most times it's not. Those are special purpose chips and you need to check the specs.

Here's a handy-dandy CPU comparison chart w/ hyperlinks to take you to the specs.  https://cpubenchmark.net/cpu_lookup.php?cpu=Intel+Xeon+X5670+%40+2.93GHz&id=1307

I really like the thought.  I would only change the term "mental travel" to the "speed of information".  Note I did not say knowledge (though it can be used for such.)  Right now, the majority of processing power and internet speed for individuals is spent on netflix and porn.

That criticism does not detract from the argument your friend made in any way.  It is an interesting point to ponder...

No speakers and 50 G's just gets you in the door.  You'll want it fully populated to bring it
up to it's 192 CPU core and 12TB of RAM potential.

So you'll need some extra goodies:
extra CPU books and heat sinks. eight Intel Xeon E7-8800 CPU's, 192 64GB DIMMS,
32 SSD or SAS drives with a couple of storage HBAs to drive them,  optics for the onboard 10Gb ethernet
ports, extra I/O books for PCIe adapters  and of course extra power supplies for redundancy.

I've took a quick run thru the online configurator and got you a new quote.  Pretty insane.

Folders - check this out - 2009. (especially Pgs 6-7)
http://www.bit-tech.net/bits/2009/08/03/how-to-build-the-best-folding-rig/1

Page 7 - all parts listed (except GeForce (upgrade to 750Ti) ) are still available. This unit can be built for just under a grand.

4x NVidia GeForce GTX 295 (not available) - Upgrade to 750Ti - $107 ea - $428 - Amazon
MSI K9A2 Platinum Motherboard - New Egg & Amazon N/A  eBay NIB   $ 150
AMD Phenom II X4 810 - $40 - Amazon
(2GB) x1 Corsair XMS2-8500 RAM - $26  - Amazon
250GB Hitachi HDT721025SLA380 - $40 - Amazon
1 KW Enermax N/A - Upgrade to Platimax 1350W 89+ efficiency PSU - $262 - Amazon

Total: $946.00

It can probably be built cheaper with a generation or two newer hardware as the parts listed in the article are obsolete and hard to find. The price bell curve for these parts is on the upswing.
