1) Message boards : Number crunching : Two projects on one GPU? (Message 69220)

Post:
Why would you want to do that?
If that would be possible, expect instability, issues and errors.
Years ago it was possible to play games on a gpu that was running collatz, but i dont know if that is possible now.
I never tried that out, i use dedicated gpus for boinc for many years now.

It is possible to run 2 different projects on the same gpu, but the projects will have to take turns running on that gpu.

Well, my local bank has millions of euros available, but they aint gonna give'm to me.
I guess that's life, usually we dont get what we want, I'm used to it by now, i just ignore it and move on.

I have just stayed away from ATI/AMD because of the challenge of installing the drivers and maintaining them. The Nvidia drivers just install and run with no issues ever. The ATI/AMD drivers are a complete fiasco as all the constant posts of issues posted attest in the forums.

True enough for the latest versions. But the RX 500 series is easy enough as I understand it, though mine is on Windows. And the power efficiency of AMD is much better here; I use about 90 watts (GPU-Z) on my RX 570 for my 100 seconds; I expect it would be more like 140 watts on the Nvidia cards.

I have a bunch of Nvidias, but they are used elsewhere (on Ubuntu).

Perhaps latest AMD drivers are having issues somewhere, I know on Seti in particular, but for my rx series I have never had a driver issue on any of my AMD cards.
For this project in particular, the fp64 performance of the Nvidia cards, at least on the consumer side of things, are pretty terrible though. Rtx 2080: 314.6 GFLOPS. Rx570: 318.5 GFLOPS. So for what now is around $100 or so you can have better performance on this project as a posed to a $1100 GPU, and use much less power to boot. Those numbers seem to correlate to real world performance on this project from what I can tell, too.
Are there other projects that heavily utilize fp64 as well?


Amd 7970\r280x has 1000 GFLOPS of fp64, and used ones are cheap even on ebay:
https://www.ebay.com/b/AMD-Radeon-R9-280X-Computer-Graphics-Cards/27386/bn_8951879
Just buy one with a good cooling. Perf per watt is still very good, regardless of 240w tdp.
That is thanks to other gamingcards having they'r dp perf cut down, cause games dont really need it.

My good old 7970 ghz edition is able to pull 500 000points per day without oc (3wu-s at a time).
Radeon VII and Titan V have better perf and perf per watt, but for a hobby they are too expensive imo.

About amd drivers, they are what they are, but they fave matured a great deal.
Been mixed amd and nvidia (gpus in the same pc) user since the days of the allmighty 1gb ati 7870cf +gf8800.

The old rule for ati\amd drivers was: when new gpus come out wait for one year for drivers to come out and then buy it. Wasn't the case for 7990 dual gpu board, cause after a year people started selling them for lack in realworld gaming performance. Synthetic benches scaled well (i was 7970 3way cf user back then), but gaming perf sucked.

Later drivers got better, but it took faar too loong for amd to get there. People were dissapointed.
And afcourse then amd quietly killed of its cf support through drivers, so for doom 2016 i bought a single gtx1060 3gb gpu, and i really haven't gone back to sli or cf since then.

Apparently radeon VII is eol now. Well that was unexpectedly fast. AMD beating nvidia at its own game?

Was looking at some hosts with a radeon VII, and the results are not that impressive:
https://boincstats.com/en/stats/61/host/detail/801752
https://boincstats.com/en/stats/61/host/detail/805181
Results are not disappointing by any means, but i was expecting a little more, like 4 times the amd 7970 performance.
Right now It looks like ~2,5 times 7970 performance.

For right now running two amd 7970 would get me into top 20 (looking at hosts only).
That would be 500w per hour vs Radeon VII 300w per hour, and afcourse theres the the gpu price difference.

Well, if it's fp64 ratio is 1\4 then it's like 7970 all over again, and that was a brutal card back then with it's 1 TF of fp64.
(Fp64 for 7970 was set at 1\4 ratio).

Post:
You set the share setting to 0 on the project that you want as a backup.

Then install a 6.12.x version of the manager.


Thanks for the info man, but i just upgraded my ati\nvidia rig, and there's no room for the 4870 in there anymore, it's nvidia rig only for now. And since my main ati\nvidia rig's ati card's are 6870 and they dont support dp, i wont be able tu run MW for now.

Hi, how to setup a backup project for milkyway? On a regular basis mw is down for short times, and mu 4870 is doing nothing. Try'd this: added collatz and set share to 0%, well it didnt work, collatz started to run has a primary project and milkyway (share 100%) was waiting to run...
Help please. Also maybe set dnetz as a backup project?

Post:
That says it all: An ATI GPU supporting double precision math is required
5770 have sp support only, you can run other projects with them: collatz or dnetc (i run collatz).

Hi, will there be support in the future for the new ati hd 6850 and 6870 series?
