Are you sure its just not a bad riser? They aren't very reliable. Milkyway doesn't really use much PCI-e lanes, but you will see improvements on fast cards running at least 8x anything less and it does hinder performance, but marginally.

Getting a kick out of a teammate who deployed a single Titan V card here running Separation tasks at 8X concurrency and still getting 3.5 seconds per task.

That card isn't showing up in the Top GPU cards list yet either.

Should go into the New Benchmark Thread for a target to shoot for.


If only those cards had more VRAM. They'd be unstoppable.

First time in history Windows Update fixed something. Need to save this thread forever.

When I need to use Windows on a BOINC only box I just install the trial version of Windows 10. It will tell you, you need to buy a license and leave a permanent watermark on the lower right of the screen, but outside of that everything else works fine. (I think some advanced features are disabled, but ive not found out what) and for BOINC it's not an issue

I had a similar issue on my Windows computer; turns out it was a SSL issue and installing a Microsoft update fixed it. (I installed BOINC before I updated Windows. D'oh)


Do you remember the update? I'm having an SSL problem at another project on a Win 7 pc


No I do not remember the update exactly. I had just installed the system and it had a lot of updates. After that all was well.

7) Message boards : Number crunching : Validation Pending too many tasks (Message 74502)

Post:
Oh yes, you are right. I didn't realize the works waiting to send was so low. I just assumed it was like last time and the work ready to send was way up there.

Something is wrong with the validator. It seems everytime the server restarts it starts working down the validation backlog, but then it stops and the validations just start to rise again. Whatever the server does when it first starts up and starts validating tasks isn't able to keep up with the amount of tasks being returned, so the few thousand it does gets over shadowed quickly in a day with the returns.

So it seems like the problems are unlikely to go away until after the migration to new hardware (and fixing the issues that might come with that) as the workunit pool overfill bug seems to be very persistent.

The WU overfill bug still doesn't explain the growing validation queue, I don't think. When the task generator creates new tasks, why does it seem like no wingman/validation tasks are being created, just new, initial ones, given the large and ever-growing Waiting for Validation queue? Overfill or not, I don't see why the Validation queue is so large and growing.


The bug is the reason why. When there are already too many tasks waiting to be sent, new tasks are not created. The new tasks are the wingman tasks that need to be created and they wont create those tasks until the WU backlog of tasks waiting to send go down enough so the work generators will start generating new work.

Post:
I can only do CPU tasks as I h a an Intel GPU which not supported. Maybe GPU tasks are validated quicker as they will undoubtedly be shorter.


Nope, I have over 200k GPU tasks waiting validation and that number just keeps increasing.

I backed a few of my rigs off it to work on something else. Might end up taking them all off to work on something else until the problem starts to resolve itself.
10) Message boards : Number crunching : Really short WU. Is that Normal? (Message 74433)
Posted 12 Oct 2022 by Skillz
Post:
yes that's normal. means that WU had more than 150k timesteps and it was aborted.

I gave the server a nap and a kick. Hopefully that fixes the slowdown. Seems to be working on my end already.


Thanks, Tom. I'm at over 125k pendings at the moment. Numbers are still going up, but hopefully whatever you did will correct the problem soon.

I wish I could use my other 7 cores leaving one free for the GPU, seems to me will only use a maximum of 16 even with the following in app_config.xml in the project folder
<app_config>
<app>
<name>milkyway</name>
<fraction_done_exact/>
 <CPU_version>
<cpu_usage>23</cpu_usage>
</CPU_version>
</app>
</app_config>


The easiest way to get this done would be running two BOINC instances on the same host. Set one for CPU only work, then set the CPU settings in the BOINCManager to only use 23 cores (It'll be a % of your total cores) and the other one set to run GPU only.
13) Message boards : Number crunching : Can't Complete WU In Time (Message 73957)
Posted 6 Jul 2022 by Skillz
Post:
If you are running them on a laptop then the laptop is probably not fast enough to complete them in time. If it was completing them in time before but it's not now, then it might be because the GPU or CPU is throttling due to over heating. This could be caused by bad ventilation like placing the laptop on a bed or carpet where the vents beneath the laptop are blocked of their is a lot of dust in the heatsink fins and vents blocking air passage. That would be my first guess.

There are different tools you can download for windows that will show whether your CPU or GPU is running at it's full potential as well as the temperature of them.

MSI Afterburner for GPUs (Better support for Nvidia GPUs)
CPU-z to show CPU information
Windows Task manager to show both GPU and CPU usage stats.

To name a few

PrimeGrid, GPUGrid, Einstein@home, Amicable Numbers, MLC@home all can utilize GPUs. So anyone with idling GPUs I would recommend joining one of those projects and setting the resource share to 0 on it. So when MW@Home comes back your systems will automatically switch to it.

And why would you assume that human pay is either a part or a big part ?
Because most people don't work for free. I'm quite surprised you asked.
Well considering its a university and most of the "staff" are students at the University who actually pay to attend. I'd say they not only work for free, but they pay to work on the project in the form of tuition.
The professors get paid. There are running costs to everything. I can't believe you think this stuff is all free. I used to work in a university and I can tell you everything you've said is utter nonsense.


Yeah, the professors do get paid, but it's not the "MW@Home" budget and donations to the project won't go towards the professors salaries.
The grad students that help manage the project get paid with a degree.

Much like all the work we, the volunteers are doing, is also... free.

The only utter nonsense here is thinking people HAVE to get paid before they're willing to help out on anything.

Because they're far too slow for the amount of data shifted today. They're too slow for a desktop let alone a server with 1000s of users. There's a reason SiDock, Universe, Rosetta, etc, etc, all use them. They all said they're brilliant. Why would you want to wait for a head to physically move from one track to another? It's an absurd amount of time to wait when 300 people want access simultaneously. Have you not seen how long the Milkyway server took to rebuild a disk while trying to cater for users? It was ridiculous.


SSD wouldn't have made that much of a difference during the rebuilding process. Tom took the project offline and it finished in around 12 hours. Now the spinners are handing things just fine. There is more to validating tasks besides just moving data around and the HDD array isn't the bottleneck.

Sorry, I know you're doing all you can. For god's sake get someone to buy some SSDs. Universe@Home loves their new ones.


SSDs isn't some magic hardware that'll solve the problem here. Not sure why you keep thinking HDDs aren't capable of doing what they've been doing for decades.
