Message 107789 - Posted: 10 May 2017 | 18:51:28 UTC

So, I have this machine with two TitanZ cards, which means 4 GPUS, all with DoublePrecision=ON, running roughly at 750-800Mhz, and that is the machine I let GFN22 use the GPUs exclusively.

I am going to replace them with four 1080Ti cards (EVGA FTW3), which will run at about 1800-1950Mhz, but there is no DoublePrecision setting in the NVidia settings for 1080Ti.

What kind of perf should I expect after this change? Same, worse, better?

I will also be replacing a number of (previous generation) TitanX cards in other hosts with factory overclocked 1080Ti cards (EVGA SC/Hybrid, SC2/Hybrid, FTW3), so I will end up with bunch of Xs and these two Z cards, unused, destined to resale.

Is it worth keeping those TitanZs in my lesser hosts that currently have old GPUs like 580/480/8600 etc., and continue GFN22 on them, or should I replace those old cards with the soon-to-be-spare Xs and use them for general purpose crunching (PG, plus all other BOINC projects using GPUs)?

In short, is there a value in keeping the Zs alive?

Thanks
Tuna

With the Titan Z, do you get better n=22 speeds with DP on or off?

Both the hardware and software have changed over the years. Hardware is not as good at double precision as it used to be, and the software now has alternate algorithms that don't require double precision. Most recent Nvidia GPUs run faster using the alternate (OCL4) algorithm that doesn't use double precision.

If I read correctly and you are replacing 2 Titan Zs with 4 1080Tis, you should expect significant improvement.

I am in a similar boat, albeit with several AMD 7990s, which also run GFN22 exclusively, and are packed into older (Core2 Quad) systems. The are dual-GPU cards with good DP performance and each GPU can finish a GFN22 in 210-215K seconds. For throughput, they are still pretty hard to beat.

I suspect the Titan Z is similarly positioned, and downstreaming them to older systems would make a lot of sense (if the power supplies can handle it).

If I had to choose between keeping Zs and keeping Maxwell Xs, I'd keep the dual-GPU Zs. They should have substantially more throughput for GFN22.

See http://www.primegrid.com/results.php?hostid=505815&offset=0&show_names=0&state=4&appid=17 for valid gfn22 on this machine. After a driver update recently, double precision turned off for a while which I then turned on again. Seems the times went down from 300K+ to 200K+.

It looks like it is faster with DP on.

It appears to run with OCL, which would make sense with DP on vs. OCL4 for the ~300K second run times, which would make sense for DP off.

My Titan Black (which was effectively half a Z) exhibited the same behavior when it was still alive.

Sorry, was in my Dr Office, waiting, typing hurriedly. :)

This settles it, then... No point in keeping the Zs. Now I can turn on GFN22 on all my 1080Ti cards... Eventually I'll have 12. ;) Plus move 2-4 Xs to older machines. Sell the rest.

GTX TITAN Z: ~60 hours (OCL: Complex numbers / 64-bit float)
GTX 1080 Ti: ~33 hours (OCL4: Number-Theoretic Transform / 31-bit integer)

(see http://www.primegrid.com/results.php?hostid=841181&offset=0&show_names=0&state=0&appid=17)


This settles it, then... No point in keeping the Zs. Now I can turn on GFN22 on all my 1080Ti cards... Eventually I'll have 12. ;) Plus move 2-4 Xs to older machines. Sell the rest.

Don't forget a Z is completing 2 units every 60 hours or so. So throughput averages 1 unit every ~30 hours.

I wonder about them power consumptions, though...

I suspect it is pretty substantial. With a 10% o/c my 7990s pull 400w+ each, so the Z can't be far behind.

Given that I will be losing 4 GPUs in 2 Zs, but instead get 12 Tis overall as I replace all my GPUs with Tis, essentially making all of my GPUs GFN22-worthy, plus the power consumption & heat generation of Z being larger than X, plus the overall betterness of the TitanXs across the greater BOINC landscape of projects, seems moving few TitanXs down to older boxes as space/thermal/power envelopes allow would still make more sense.
