Just grab the entire BOINC folder and move it to another drive temporarily. Then once you have Ubuntu Desktop installed, move the folder back to the Desktop.


Well the good news is I am running plain Ubuntu. Finally. It was reluctant to upgrade its drivers to Nvidia, much less one that works with CUDA91.

After I got that done and "everything" working. I discovered I can't get anything to display unless I run only 3 gpus.
The bios displays just fine. The OS doesn't. :(

Since the whole idea was to test 5, 6, 7, 8 gpus.... I am troubled more than a bit.

Found you - thanks for the hint.

I see host 87174, with the Ryzen humming along happily.

But unfortunately, I also see

Device peak FLOPS	53.00 GFLOPS
Max clock frequency:	1251Mhz
It looks as if you're running the driver that reports sane values, rather than the insane one. You have 10 tasks validated as I type: fortunately the scheduler is testing out two different app versions, so we haven't quite switched to APR estimates yet, but it's getting close.

So the test result is inconclusive: we can't tell whether it's working because of Eric's fix or your driver, but at the moment my money is on your driver. Thanks for trying, anyway.


Ok, so it sounds like I should continue to let it run. Until you want me to switch to a "bad" driver. As far as I can tell I am now running the latest All in One driver.

TY. Let me look again :)


I am going to go research for some kind of better tool to try to read the log. The previous log doesn't show a shutdown, a crash, nothing. It just stops.

Ok. I give up. Either tonight or tomorrow morning I will be installing the Ubuntu desktop. I have set Seti for NNT and then I will backup the xml files in Boinc. Re-install etc.

Then I should be able to follow advice :/

edit-
Since I only have the iGPU task running at 50% it took 10 minutes. Estimated time left 10 minutes. This is the fastest processing I have seen on the iGPU. So running cpu processing even at 80% of the cpus isn't low enough to allow the iGPU to process at full speed.
More testing. :)

Ok, I have finished re-jiggering the Seti/Beta/Work location so it is asking for 50% of the iGPU. So everybody should be crunching. I have been registered under Beta for a long time so I don't mind running the ATI tasks until someone says we are done.

I understand we are probably already tested but if Eric has to do another change and test, its already processing on my end.

OK, another reply from Eric: Beta has been updated, and we're ready to start testing.

First, please reduce you cache size/work request. We are looking for a problem which should only last for 10 tasks. If the solution works, you're cured for good, and that machine won't be useful for testing this type of problem ever again. Only if it fails can you help test the next attempted fix....

So, with a reduced cache setting, go to the tools menu in BOINC Manager. and click the first item, 'Add project...'

Ignore all the information on existing projects - you won't find Beta there. Go straight to the last box, labelled 'Project URL:'. Paste in

http://setiweb.ssl.berkeley.edu/beta/

Click 'Next >', and fill in your details. Please use the same email address and handle as you use elsewhere - it makes it easier to find you. The rest is self-explanatory.

You'll get one task immediately for each of your devices. And then it'll ask for more work seven seconds later - you did set a small cache first, didn't you? Beta is different - no five minute pause to think about things.

We're interested in the AMD GPU tasks only. Please note the initial runtime estimates, the actual runtimes, and anything else that catches your eye. Post it here, and we can pick over the entrails in the morning.

Set 'No New Tasks' as soon as you want, and go back to your normal projects / cache settings. Thanks in advance.



Ok, squeezed the tasks down to 0.01 day. Suspended Seti so it wouldn't get in the way. Got my "work" location setup for ATI gpu's only. Have aborted all the other beta tasks. Crunching now.

Also, finally got both the internal gpu and a discrete card (Nvidia) setup but Nvidia is not crunching.
Have at least 10 tasks downloaded.
Will report more as I notice it.

-edit-
Since I only have the iGPU task running at 50% it took 10 minutes. Estimated time left 10 minutes. This is the fastest processing I have seen on the iGPU. So running cpu processing even at 80% of the cpus isn't low enough to allow the iGPU to process at full speed.

@ Tom M

I see host 8671627 - Ryzen 5 2400G created 14 Feb 2019, 19:51:26 UTC. That sounds like the one.

I also see 113 error tasks. The first one I spot-checked contains:

Exit status		197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED
Run time		11 sec
Device peak FLOPS	1,814,198.76 GFLOPS
Max clock frequency: 	42949672Mhz
That's a full house of the problem symptoms we're tracking. So, please take a note of what settings you were running 24 hours ago, so that we can replicate them for Beta testing.

BTW, that task was completed at 14 Feb 2019, 18:30:34 UTC, before the host was created. Trying to change too many things at once to get a host running quickly can cause problems like that.


It now occurs to me that the above creation date after the task was run has to be a result of the merge I did on the ids.

If it logged off the current user, then that is shown in the system log. Pretty simple to see the event preceding the logoff and that would point to what is causing the instability. Look for the big break in continuity of the time stamps in the log before you logged back in.


I am still learning how to get to the right part of the system log. So I am still not even seeing the startup/re-boot.

OK, it looks as if your particular Ryzen doesn'r suffer from this bug. One of the other testers reported that it only showed up when he used a non-standard CPU speed (he downclocked it). Eric found host 8669611 while checking to see how widespread the problem is: user has been a SETI member since 2005, but has never posted on the message board. He attached a new Ryzen last Sunday (10 February), and had trashed 450 tasks by Wednesday. His CPU cores are working, so he probably hasn't even noticed.

But the project - all projects - could do without that 'help', which is why I'm taking this so seriously.


I will admit to turning off the "cool 'n quiet", the C states and setting the iGPU to forced so I can try to run a gtx 750Ti beside the iGPU like I did on the previous MB. But I haven't touched the cpu speed.

This last re-boot I did set the iGPU to 1500 (it was stable on the last iGPU) and the iGPU voltage to 1.2.

If it starts trashing tasks I will switch back to auto.
--edit---
I just looked at the error listing on the website and I appear to have been throwing errors since yesterday. That was with the cpu/gpu on auto and the older drivers.

The error is "exit time limit exceeded".

Now what do I do? Shut down gpu processing?

I want to leave it running for a little while because I have different drivers installed as well as the standard high power plan.
Yesterday I was still running the "Amd balanced power plan" that even with "never stop" was pausing the system.

Post:
What’s happening when it quits?

One symptom you can look for to see if bad USB cables might be causing problems. With the system running, run nvidia-smi -l to keep the nvidia-smi loop running every few seconds. If you see one or more cards that are running below 90% all the time, it’s likely a bad USB cable on that card. With everything working properly, you should see 95+% GPU utilization nearly all the time (except when moving to a new WU where it’ll briefly drop to 0).


I come in and logon and all the programs I left running are gone. Its almost like it rebooted and self logged on. Since I have the bios set for power off instead of power on when it looses power and I require a logon password I am pretty sure it is not re-booting.

I can try the looping for nvidia-smi. So far the only times it shows below 90% is when it is ending/starting a new task when I manually check.

If it runs continuously with no problems for a couple more days, I will add the 7th gpu back in and continue to watch the system log.

If push comes to shove it will simply be a 6 gpu system. But if I can manage to tinker with something so I can run 7 or 8 I will.

While I can't say for the future, at this stage I think I will suspend the idea of trying to get a copy of your system up (eg. new MB) for two reasons. 1) Its doing pretty good already. 2) You had to down grade your cpu chips. The only down grade I have for the cpu's would be all the way down to e5-2670's.

If you do try to revert to the CD drivers after the test with the latest drivers, I would suggest using DDU to completely remove any vestiges of the troubled new drivers before reinstalling the good CD drivers.


I have been using the custom/clean install. If you have mentioned "DDU" before I failed to note it down.

We think the problems arose in a more recent driver, downloaded from the internet. That would be a useful test: Bill was working fine when he first attached his Ryzen to SETI on 23 December, but he had his first failed task on 4 January. That sounds like driver 19.1 to me, so that's what I put in my bug report to AMD.

If you could install something like that from the AMD website, that would be awesome.

Thanks. Please let us know whether - with the standard client - you see the crazy speed reported at startup.

I've emailed Eric with the Beta suggestion, but he won't have received it yet because of the time zone difference. Hold off attaching to Beta until we know whether he can deploy something to test.


I had to re-install Windows, then install the drivers on the CD-Rom and then re-install Seti. I am not seeing the really large Gflops number (yet). So either I am missing something. Or all my changes have "fixed" something.

Thanks, but we've actually moved on from that stage. The patched client seems to be showing what we need now - no further testing needed on that.

Which is more than can be said for the servers - it became apparent on Wednesday that work is needed there too. I'm going to suggest to Eric that our 'SETI Beta' project might be a possible venue for testing, but I don't know if it's in the right condition to accept the preparatory code which has been written so far.

Don't do anything yet, but if we do get a test started, would you be willing to attach your Ryzen to Beta briefly to see if it works?


My 2400G is back on the air. And I will make the requested client change. I can add Beta back if you want.

Post:
Does inflating your GPU count get you more work for your GPU'S ?


It also provides a way to "automate" bunkering up (storing more gpu tasks) for the Tuesday maintenance outage.
When the Seti servers are working right, you can get all the gpu tasks you want for processing. All you have to do is set the "extra" days processing to something like 0.1 and the client will keep connecting with the server often enough that you won't run out of tasks. If everything is "normal".

Mostly the issue of running out of gpu tasks is an issue for machines with the faster gpu cards. For slower cards, they don't run out of gpu tasks during the Tuesday outage. The same is true of higher than 4 core count cpu's. They run out of cpu tasks during the Tuesday outage but the slower/smaller machines don't.

Post:
Hi all. After a long time, I am resuming my SAH crunching. I have a few questions regarding GPUs and Win10 machine advice in general:


@ejthedj
I took a look at your raft of systems.


I apologize. After a while I finally remembered that many older generation Intel iGPU's were labeled "4000" and "5000" etc. So my advice should have been put those in the CPU-only group.

Some of the 3 digit iGPU's may be significantly faster. Especially anything with "Iris graphics". I don't remember about the rest.

The older the design of the Intel cpu chip the more likely that crunching with the iGPU will slow the entire system down and lower production.
