Wow, looks like he's already at 10 years. That's incredible. I will have a meeting with Sidd, Jeff, and Eric to brainstorm new membership time badge ideas.

Hey Everyone,

Just wanted to explain the validation inconclusive rates after this maintenance, and most maintenance. This is not an issue with how quickly our database can handle the workunits, but how quickly our users can cross validate workunits. As many of you know, we can require up to 4 other users to cross validate workunits before they are considered valid.

At any given time, we have 300,000+ workunits being calculated by volunteers. When we take the server down for maintenance, many of these are completed while we are down. They are then all sent back to us at once to be validated, so we end up with a queue of 300,000 workunits or more that have to be validated by other volunteers to catch up. This doesn't require much work for our server or database, but it does take a long time for users to work through them all.

Sorry that there is such a backlog for validation.

Hey Everyone,

Our database maintenance is coming to a close. We should be done by the 5pm today. It has been several months since we were down for maintenance last so it is taking us a little while to clean everything up.

As far as future plans, it is actually within our budget to upgrade the server and we plan to do that within the next few months. Otherwise, we have a few maintenance periods planned in the upcoming weeks to help optimize the database. In the last few months, it has been running pretty smoothly, but we think we can continue to improve it.

Thank you all for your continued support.

Hey JohnDK,

I had no idea their maintenance day was Tuesday. We just picked this day because its one of the two days that Jeff is in the office. This won't be too common of an occurrence and will consider switching to Thursdays. I just wanted to avoid being so close to the weekend when starting maintenance.

Hey vseven,

We have to walk a fine line with the number of workunits we allow users to download and their deadlines. We have both CPUs and GPUs that we have to balance with vastly different work times. I think what we have now is a reasonable compromise, but I would be open to hearing your suggestions.

Hey Everyone,

Recently, we published a 100 page thesis on my work and a 30 page paper. Sidd is also working on an Nbody paper and thesis that should be done by the end of the year.

Thank you all for your continued support.

Hey Everyone,

I just got pointed over to this thread. Wow you guys did a deep dive into this issue. Thank you for that. If someone already has the fix for this coded up, you can make a pull request on the source on Github. If you do that, I will do some internal testing on the new code and push it out to users sometime next week. If you do not want to do that, I will read through this thread and try to implement the fix myself.

Thank you all for all of your help,

Jake

Hey aad,

That's strange, sorry about that. I will double check the credit calculations before the next set of runs go up.

Thanks,

Thank you.

It doesn't change much for MilkyWay@home. We will continue working on mapping other structures in the halo and I will continue working as a post doctoral researcher.

Hey Everyone,

I put up a few new separation runs. You may notice that these have slightly different run times. The credit awarded should reflect the run time.

The run names are:

de_modfit_sim19fixed_bundle4_4s_NoContraintsWithDisk260_1
de_modfit_sim19fixed_bundle4_4s_NoContraintsWithDisk260_2
de_modfit_sim19fixed_bundle4_4s_NoContraintsWithDisk260_3
de_modfit_sim19fixed_bundle6_2s_NoContraintsWithDisk140_1
de_modfit_sim19fixed_bundle6_2s_NoContraintsWithDisk140_2
de_modfit_sim19fixed_bundle6_2s_NoContraintsWithDisk140_3

If you have any questions or issues, let me know.

Hey Everyone,

I just wanted to updated everyone on some of the current scientific work and results coming out of MilkyWay@home. These results can be found in my PhD thesis which I posted here.

The major result from this work is that we have mapped 7 stellar streams in the Milky Way halo. We believe two of these streams are likely to newly discovered streams.

These results would not have been possible without the contributions of the MilkyWay@home volunteers. Looking forward we hope to improve our mapping algorithms to find map new stellar streams and better fit those we have already found.

Thank you.

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.
