Howdy!

Have a couple questions.... especially where a Ryzen 9 5950X is concerned...


1) Why are N-Body tasks limited to 16 CPUs?

2) Why can't we set how many CPUs N-Body uses?

v166 is still being downloaded for the 1.13 tasks... and they still all fail... sigh...

Newer 1.31 tasks complete fine...

I watched several 1.42 WU's before I disabled downloads...

Seems they run all on CPU and don't use the GPU at all! They take 4000 seconds more or less and do in fact complete, but no GPU activity is seen.

Is it my drivers or something? This on a Win 10 setup with 280X board.

It used to work well, then it pooped out, then it started working well again, and now the same problem.

Have a setup with two AMD 7970's and I only get a few or none WUs for each request... then wait at least another minute before I can try again. The setup clears WUs so fast that a minimum of 30 WUs is needed to keep it working...

Sigh...

Well, my GPU issue is I can't keep them busy anymore...

The server seems to have slowed down. I can't cache enough WU's to keep busy!

I run 2 WU per card and have two 7970's and one R9 280X doing Milkyway...

It always pauses 1 minute after each update and buy the time 1 minute expires, the WU's are already all done OR the setup requests more work and gets none/little several times in a row!!!

I might add that some playing around with clocks and memory speeds on the GPU's has allowed me to sort of tune the setups and greatly reduce errors...

I get funny waveforms in MSI Afterburner using 13.2 moded drivers OR using the latest 14.2 drivers. CPU makes no difference.

The only difference between the E3-1230 setup and the 2600K setup is the PCIe bus speed... PCIe 3.0 vs. 2.0.

Notice it sometimes drops into low clock mode, a slight change of the clock speeds below default corrects it... or seems to.

I've run the clocks as low at 580MHz and seems the slower speeds create fewer errors...



In any case, there is something weird with the modified fit WU's for sure. Both setups perform the same weather using reference 7970 or latest Saphire R9 280x.

Well, I've had some Modified Fit WU's get hung on 2 systems running them... abort them and the system hangs for some reason... reboot and things running better now. Seems there was something wrong with some of them.

Also, I was getting very strange GPU Usage waveforms from them. They seem to have settled down now...

All of this is obviously a coding problem on the project side OR something wrong with the BOINC control side or possibly both. I simply don't know...

Anyways, off to other places for a day or two then be back...

I hope the folks can figure out what is wrong...

I've tried 2 versions of windows (re-installed twice from scratch), tried three (3) different 7970 cards, tried everything I can think of and running pure stock speeds with NO overclocks and I still get a a lot of validate errors on modified fit tasks as before...

http://milkyway.cs.rpi.edu/milkyway/results.php?hostid=612072&offset=0&show_names=0&state=5&appid=10

Hope this helps... other tasks seem fine... other projects no problem either.

It's still only the Modified fit tasks giving me INVALID results... I have the E3-1230 and 2600K setups running ONLY modified fit tasks now for you... I also may add that from time to time a WU fails quickly and has caused a BSOD or more often causes the GPU to reset to a low clock speed and stay there... Driver versions make no difference.

Hey guys - any chance you can post the log output on the errored units? Or link us to one of these results? We need something to go on...

One of the advantages of the forums is that posts can get community support. Since we do not have access to every possible hardware configuration, this is usually the way to go. If you have an issue that you think needs to be addressed directly by the team, you should send it to our email address, which is displayed in various places: astro[at]cs.lists.rpi[dot]edu


Sure...

PS: I might add that last I checked, my 6970 or 6990 cards don't work with newer tasks with OpenCL drivers past 12.4 without major errors... but they work fine with later drivers on other projects... might have to test that again... In fact, I think later drivers mess up with 7970/ R9 280x as well..

... results are "born" with quorum and replication = 1, which is increased during their lifetime.

Situation changed, my host seems to be classified "reliable" now and results are accepted without having a wingman.

So that configuration setting does have the potential to increase the overall project performance.


Well, I'm still getting about 1.5% errors on Modified Fit tasks on ALL systems, even the E3-1230 setup...

The problem is NOT with my hardware, but rather with the MW code somehow... and still no response from the managers...

You know, we paid to keep this project going, would be NICE if they could support us a bit, unless they will be giving up after funds run out again...

So far so good on the Sabertooth... running like a clock since I replaced the suspect mobo...

I suppose the error rate is going to stay with us as well... mine is decreasing now and is less than 1% overall... happy with that! Like my OLD Sabertooth 990X as well...

Hi all

Back crunching after a very long time away.

I keep getting errors but only on MilkyWay@home 1.02 units.

I am running a 5850 card with the latest ATI driver. If I remember correctly sometimes it's the driver that's the problem. If so which driver should I be using and where can I find them.

Thanks all, it's good to be back. Even though my brothers infected computer was still crunching, lol.


If you are having driver problems, you may try the 12.4 moded drivers... These are the only ones that work with my 6990...

Hmm, seems one of my systems lost a Mobo... the 8x8 PCIe 2.0 one... sooo, replaced it with a Sabertooth 16x16 and going to try the dual card thing again...

Seems the Mobo lost a PCIe lane on one slot... that is possibly due to a card that went bad some months ago.

It is possible the DUAL card tests are not so accurate because of that.

Anyways, we will see... running a 7970 and GTX 670 together on the Sabertooth to see how it goes..

You using newer drivers?
