Can Einstein handle 3.5 PFlops offered by NVIDIA's K20? Cuz I'm thinking about buying one.

I had good laugh on this! :D Thank you!

RE: NVIDIA's K20 GPU has

Quote:
NVIDIA's K20 GPU has 2496 CUDA cores and offers a Peak single precision floating point performance (board): 3.52 Tflops for only 225 watts!
My question is, Can Einstein use all of those cores if I were to buy one? Would this GPU be used fully?
What would happen to the Einstein@Home community if one or two of the GPUs were to come online?


Titan should be faster for DC at 1/3 the cost (but still too expensive). 2 x HD 79xx should be faster than either at even less $$$. Power efficiency should be no better than the lower cost alternatives IMO.

I see there are hosts

I see there are hosts sporting Titans now - and here's a host with two of them.

It would be very interesting to know how many WUs they're running concurrently, in fact it would be nice to have this information in the results file. If it's there I'm missing it...

Quick look at those hosts

Quick look at those hosts last contact log's suggests 5 at a time per card.
GPU utilisation is set at 0.2 with an effective runtime just shy of 10 mins. per task.

Which means 6 wu's per hour.

My Sapphire HD7870 XT finishes 4 wu's per hour and I paid ~216.- Euro.
Power consumption < 180W when running 2 wu's at a time

Supporting CPU: i3 ivy bridge @3.3GHz, slot: pci-e3 @ x8
http://einsteinathome.org/host/6633241

A look into the statistics / best computers gives a clear picture:
places 1-5 AMD, place 6 a PC with 4 Teslas C2075.

I'm happy with my decision.

5 WUs at one time, ~10

5 WUs at one time, ~10 mins/WU equals 30 WUs/hour .....

Maybe not so clear, it's 50 minutes or so for 5 tasks: 6 tasks/hour.

This is how I understood it. The runtime for his wu's are reported as ~ 3000sec which points more to my calculation than to 30 wu's/h
