Interesting, it looks like the Titan is running about 35-40% slower than an HD 7970 with 5x WUs and around the same speed as an HD 7950, according to this chart at Einstein:

http://www.dskag.at/images/Research/EinsteinGPUperformancelist.pdf

I don't even see a Titan on that list...

Take another look, maybe you missed it ;-)

I don't think the reported memory is the problem with Titan. The apps only use as much memory as necessary anyway, and 4 GB is still plenty (be it for 1 or 2 GPU-Grids or 5 Einsteins).

And regarding Titan and CUDA 3: each SMX is pretty much the same as for the other Keplers, just with some more features (more FP64 units etc.) and more registers. If these features are not being used, it should perform just as well as any other Kepler with this amount of shaders and clock speed.

MrS

And yet the Titans fail to run any GPUGrid WUs still. If they're all in the Kepler family what's the problem?

It's software, for sure. I can't tell you more, though, since I'm not a GPU-Grid coder.

Scanning for our furry friends since Jan 2002

I have done a little performance tuning but I think there is more work to do yet.

I have reduced the workload to 4 WUs per Titan now because my CPU has only 8 threads.

I am now averaging 2600 sec. per Einstein GPU WU with an average daily of 87,453.02.

Just waiting for GPUGrid apps I can run instead.....

You should post this to dskagcommunity so he can update his excellent chart:

Already done, i visit the most forums from my mainprojects every day to look whats going on AND if all of my unattended machines running fine ;)

BUUUTTTT, 87k credits? Do i something wrong? My chart calculates ~66,400k

((60secs*60mins=3600secs*24h=86400secs/average calc time 2600secs)*4WUs)*500Credits per WU=~66400

I didn't do any calculation I just copied and pasted the RAC on the account page.

In fact today's RAC value for ID: 6889477 is: "Recent average credit 88,240.40".

After reflection, I now realize that the RAC and the daily may not be the same.

Thanks,

Operator

RAC and "average credits per day" are the same. Did you include RAC from other cards or machines or CPU work?

MrS

Scanning for our furry friends since Jan 2002

He ran 5 WUs before, so the RAC is higher than actual until the next two weeks or so i think. Then it should be ok. We will see ^^

Nope. All that machine does is E@H GPU work. There are two Titans in that box.

And today's RAC for that machine/project is: 89,855.65 probably due to a little more tweaking on my part.

Just waiting for GPUGrid work.....

And today's RAC for that machine/project is: 89,855.65 probably due to a little more tweaking on my part.

RAC is a VERY poor way to calculate current production. Take your average WU time in seconds, divide it by the number of WUs run concurrently and divide the number of seconds in a day (86400) by that number. So on this case: 86400/(2600/4) and multiply that by credits/WU (in this case 500) and you get 66462 credits/day. Simple and accurate. RAC changes due to a variety of conditions and is not accurate for our purposes.

Your output for running 5x WUs is higher:

86400/(2950/5) * 500 = 73220

Just bumping this thread.

Any update to Titan compatibility with gpugrid?

-- Craig

Has there been any analysis of any type performed to determine why no GPUGrid apps will run on the GTX Titan?

Anything?

I was under the impression that the developers/programmers now had a GTX Titan (or two) to use in their development process.

Yet we have heard nothing at all as to what the issue(s) are.

Is there anybody successfully running a GPUGrid app using a Tesla K20 or do they have the same problem?


Will there be a date that we GTX Titan owners can expect to be able to support the GPUGrid project with our hardware?

Thank you.

In programing you cant give a date when you fix some problems, thats why so much games are such a shit today when the developer want to bring it out @ a special date ;)
