Hello everyone,

Announcement
I will be doing some server maintenance on 28 Feb 2024 at 15:00 UTC. The server should only be down for a couple of hours.
I will also be putting up new runs under a new application called Milky Way N-Body Orbit Fitting.

Update
- Fixed error causing warning messages to appear on people's profiles and on the Message Boards
- Removed the quotation mark that was appearing at the top of the home page

Working on
- GFLOPS error
- Cause of runaway WU generation

Thank you,
Kevin

Hello everyone,

I am working on getting a new version of our code up on the server.
This new version will allow us to fit orbits on top of the other parameters we have already been fitting.
There seems to be a slight issue right now with downloading the new version and I am working on fixing the issue.

Thank you,
Kevin


Update
Download error has been fixed but the error with the new version persists.
Working to get the new version working and getting new runs that have orbit fitting up on the server.

Hello everyone,

Update
I've been working on trying to fix some of the recent issues with the server. Here is what I have done to solve them:
- Cancelled all Separation WUs that were still creating tasks such that now the "Ready to send" tasks match (hopefully this is the last of the Separation WU's that were still creating tasks)
- Set all validated tasks that had 0 credits to "inconclusive" and set the WU to need validation so that tasks are made to validate the 0 credit task and assign them credit after validation
- Cancelled all with unsent tasks to lower the "Ready to send" number (I will be keeping the WU generator off until the numbers are lower so that this number continues to go down and tasks for validation get sent out)

I will keep watching the numbers and some of my own inconclusive tasks in order to make sure that these fixes worked. Please let me know if these fixes are working or not working for you.

Announcement
- Having done this, I will be running another server maintenance on 29 Jan 2024 at 15:00:00 UTC. Again, this should only be for a few hours at the maximum.

Question
- I do not see the PHP warnings anymore on the result pages. Is this still an issue that people are seeing? Please let me know if it is so I can take a look at it.

Working on
- finishing testing on new binary with orbit fitting
- fixing the cause for runaway task generation

Thank you,
Kevin

It seems that all of my pending jobs have now been marked as validated with no credit - is this a temporary problem? (ie https://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=963887023)


I will take a look at that.

Hello everyone,

I will be running some server maintenance on 22 Jan 2024 at 15:00:00 UTC.
The server should only be down for 2-3 hours. I will post an update when the server is backup.

Updated on the server:
- Server should be running faster now

Working on:
- WU waiting for assimilation and validation
- Reducing the number of "Ready to send" WU
- PHP warnings on result page
- testing new binary with orbit fitting

Best,
Kevin

I guess you need to cancel separation tasks "waiting for assimilation" now, so they can finally be removed from our results lists.

Regarding one other change that appeared after the server maintenance: is ~3 million ready to send N-Body tasks the new target for the work generators? With that it will take up to two weeks before the _1 and any additional resend tasks make it through that pile (when we had 1.5 millions they needed around 5-7 days).

And since N-Body seem to always need two results to validate, wouldn't in make sense to set minimum quorum and with that initial replication to 2 ? Or are there any WUs, that validate with only one result?


I am not sure why 3 million workunits were generated. The cap was set pretty low to 1000 (now 10,000) but it just ignored that which I still haven't found the reason why. I will try to go in and remove/cancel these workunits so validations can be done.

Here is a quick update on what has been done with the server:
- Special badges have been given to Volunteers who had them
- Cancelled all of the "Ready to send" separation workunits

Currently working on:
- fixing slowness of the server

Kevin,

A quick thought regarding "Admin only" threads -- if there's a facility that lets Admins lock threads you could create a thread with an initial message then pin it and lock it. When you need to add to it, unlock, post your next message and lock it again. This would, of course, need testing in case a locked thread can't be unlocked again :-)

If someone manages to post to the thread anyway, just delete what they post (possibly after copying it to a more appropriate place?) The first message would, as suggested elsewhere, include information on where to discuss the topic of that message, so such action seems fair :-)

Cheers - Al.


That's a good idea. I'll give that a try.
Thank you for the suggestion.

Hello everyone,

Thank you for the responses. Now that classes are out, I can put more time into implementing some of the changes you have requested.
Namely:
- admin only update thread (not easily done and I will have to change the code in order to make this work unless someone knows of an easy way to do this)
- getting rid of the PHP warnings that are coming up in the WU pages (I will be able to do this after I make sure the warnings are not affecting anything)
- getting Mac support
- adding the special user badge for those that had it before

As for GPU support, there were some talks about users maybe looking into getting that supported again. The current code is outdated and not any faster than the CPU code.
Supporting this code on our end is not really possible at the moment so there are no plans as of now to get GPU support for N-body.

A new version of the N-body code is in the process of being tested. We hope to be able to release this new code early next year after testing is concluded.

Let me know if there are any other changes or improvements I could make with the project.

Thank you,
Kevin

So these warnings don't seem to be affecting actually downloading/running WU's. I had WU's that also had these warnings but they were credited.
I think there was a period when the workunit generator might have made bad WU's.
These should pass over as they get crunched.
Has anyone with this warning found otherwise?
I will keep the warnings up for now but will remove the warnings after I figure out why exactly this is happening.

Thanks for that,

I did delete the project then I added it again. But something very strange happened. I was allocated 96 work units, but they never downloaded. They were stuck in some sort of downloading limbo mode, so after several hours of not completing the download I reluctantly aborted all 96. I think a lack of heads up, about what was happening caused both confusement and frustration.


Is this still happening for you? Or are you now able to crunch?
The initial errors the came through about a week ago I am not sure why they did not appear when the migration happened.
I didn't realize the recent DNS change would cause the errors it did which is way there was no heads up on the necessary DNS change to fix the errors mentioned above.
This just come down to me being very new with dealing with servers and BOINC so I apologize for the confusion and frustration.

I was just now able to upload about 250 WU's. And a lot of them had credits. A lot were also _0 tasks, so not expecting any wingman activity for a while. But I am getting this funkiness:

If i scroll down through the funk, the regular status display is there, and seems good.


Another user also noted this issue.
" These problems occur only when certain "older" tasks are shown in the selected table. E.g. tasks which were downloaded at 29 Nov 2023, 18:23:26 UTC are bad, tasks which were downloaded at 29 Nov 2023, 21:13:27 UTC are good." is what xii5ku noted.
I think this has to do with when I deleted the binaries from the database and put them back up with the correct URL.
Is this causing issues with WU's?

My results tables on the MW@H web server show "v0.00" in the Application column now. I would have expected "Milkyway@home N-Body Simulation v1.83 (mt) x86_64-pc-linux-gnu" there, or something like that.

If I filter the results tables (click on items such as "Validation inconclusive" or "Valid" etc.), lots of PHP warnings appear above the results table.

(Seems to be a mere cosmetic issue, as far as I can tell.)

Update:

Nevermind. These problems occur only when certain "older" tasks are shown in the selected table. E.g. tasks which were downloaded at 29 Nov 2023, 18:23:26 UTC are bad, tasks which were downloaded at 29 Nov 2023, 21:13:27 UTC are good.


This might have happened when I removed the 1.83 binaries from the database and put them back in so they would be linked with milkyway and not milkyway-new.
