Posted 15 days ago by Profile Jake Weiss
Hey Elvis,

I looked through your workunit history and it seems as though the problem occurs on the second to last, or last workunit in a bundle. Can you please look to see if your GPU is running out of memory, or if there is another issue where you drivers are crashing late in the workunit?

I am sorry you are having issues with your project and I understand your frustration.

Hey,

That's really strange. I'll keep an eye on it and if it doesn't fix itself, I'll give the validator a reminder to check it.

Hey everyone,

Sorry, I've been sick the last week or so. Seems like there have been a few issues, but I am not really sure what they are. Some also seem to be Nbody issues, Sidd has been informed about them, and I have encouraged him to be active on the forums. Hopefully he will be.

Any separation issues can be posted here and I will take a look at them.

Hey Everyone,

I just put up a bunch of new runs named:

de_modfit_XX_bundle4_4s_NoContraintsWithDisk_1

where XX goes from 09 to 23.

Let me know if you see any issues with these runs here.

Thanks everyone,

Jake

Hi Contact,

There was a problem using a Group By statement in the database query for new users. As a quick fix, I just removed it. This means names can show up more than once as a new user, but I don't really think that's too big of a deal.


As for the founder issue, I actually tried it and simulated a 60 day wait time on our database. The functionality definitely works assuming the date is set correctly when a request is sent. I'll check on that today. Chances are, you will have to wait another 60 days once I get it working though. That seems to be the only fair way to make sure the system isn't getting cheated.

Nicklw,

On the website go you "Your account," then "MilkyWay@home preferences," then "Edit MilkyWay@home preferences." On this page you will see a "Run only the selected applications" section. Uncheck the "MilkyWay@Home N-Body Simulation" option. After your work queue clears out, you should notice no more N-Body workunits.

Hi Contact,

I found the query that is causing that database error. I am working on a fix for it now. It doesn't seem like an issue that would prevent team transfer though. We will see.

Jake

[Edit]
I fixed the issue with the database error. Changing founders does seem to work, I am not sure what method you were using though. Maybe you can give me a little more direction to where exactly you were seeing an issue.

Hey Nicklw,

To solve this problem temporarily you can set your preferences to not accept Nbody workunits.

Contact,

You are talking about on the edit profile page. Oh! The original question was about the create profile page, which is different. I didn't even look at the edit profile page. I am sorry.

I will get the edit page fixed up right now. I see there is no reCaptcha there now.

Jake

[Edit]

All fixed.

Hey Contact,

I'll give it a try. I still have not actually been able to reproduce the issue on my end over several different systems running different configurations of hardware and software. Hopefully this fixes it for you.

Jake

[Edit]

So I looked at the page again and as far as I can tell, we are including everything where it belongs. I removed the var Recaptcha.... bit and maybe that will fix it. Let me know.

11) Message boards : Number crunching : My number of "invalids" decreased. How is this possible? (Message 67359)
Posted 19 Apr 2018 by Profile Jake Weiss
Hi BeemerBiker,

It looks like the likelihood calculation is actually not being completed correctly for some small percentage of your work. Is it possible that you are running more runs than your card has memory for? Since we've moved to bundling workunits the size of a single run has increased to 500 MB on the card. Normally if you run out of memory OpenCL is supposed to throw an error, but in my experience, OpenCL sometimes fails to do what you expect it to.

Nicklw,

Separation runs are single threaded or GPU only so this definitely seems like an Nbody issue. My guess is that the simulation is incorrectly calculating the remaining time. Towards the end of the simulation Nbody does extra calculations per timestep to determine if it is done which can cause the workunit to take a little longer than predicted to complete. Sidd is aware of the issue, but I'm unsure if he has a solution planned yet.

Sorry I can't be of more help,

Jake

Hey Everyone,

I made some more configuration updates to improve database stability. If you notice any database errors, please post about them here.

Hey Nicklw,

Can you tell me if these are N-body or Separation runs? If you copy the name of on the troublesome workunits and post that here, I will better be able to assist you.

Hey Everyone,

I just put up 14 new runs. These are de_modfit_XX_bundle5_NoContraintsWithDisk_1 where XX runs from 09 to 23. Each of these is using a different parameter and star file so its very possible that there was some human error on my part putting them up. They were all tested beforehand but if you see any issues, please let me know with the name of the run that's giving you trouble.

Some of these runs have some extra calculations due to the run requirements so their runtimes will vary slightly. The credits should scale accordingly.

The database issues are not related to the maintenance. At this point, I think most of the database issues come up when we are running backups or dumps for boinc stats. In the background, I am looking for ways to make that more efficient, but it will probably be a while.

Hey Wisesooth,

It looked like one of the pins was actually bent. It's a pretty old motherboard and the server still works with the one CPU in it. For now, we will just leave it running on the one. Thanks for the information.

Hey everyone,

We are going to do a quick hardware upgrade for the server. We will be down for the next hour or so. Sorry for the inconvenience.


Jake

[Edit]

This down period is concluded. We couldn't finish the upgrade due to a bad CPU slot on the motherboard. We are going to defer server upgrades for a while until we decide if it is worth it to replace the motherboard.

Thank you all for your patience,

Jake

Hey BETA and Bill,

I am still working on this issue. I have not been able to reproduce the issue on my end still so it will take a little while to figure out what is going on.

Sorry for the long delay on fixing this issue.

Hey BeemerBiker,

So the runs I put up a couple of days ago have a few extra calculations in them, so they should take a little bit longer. Your credits should have been adjusted accordingly.

Please let me know if you aren't getting an increase in credits for the increased work.

Jake
