| New D3RBanditTest workunits |
|
Dears,
as you may have noticed, we sent a new batch of WUs for a new experiment. This time the WUs are rather large and require relatively new cards. For reference, should be ~18h on a 1080 Ti.
Thanks!

| https config ongoing (done) |
|
There was a short timeout of the server because Iam still testing the config but it will take some time. Have some help here. Got certbot and letsencrypt running with a successful message but the apache config is still messy. I hope I can find a way to setup this after years.

| New Separation Runs 2/3/2021 |
Hey Everyone,
The following Separation runs had to come down due to the server outage:
de_modfit_80_bundle4_4s_south4s_bgset_4
de_modfit_81_bundle4_4s_south4s_bgset_4
de_modfit_82_bundle4_4s_south4s_bgset_4
de_modfit_83_bundle4_4s_south4s_bgset_4
de_modfit_86_bundle4_4s_south4s_bgset_4
I have put up the following new runs on the server:
de_modfit_80_bundle4_4s_south4s_bgset_7
de_modfit_81_bundle4_4s_south4s_bgset_7
de_modfit_82_bundle4_4s_south4s_bgset_7
de_modfit_83_bundle4_4s_south4s_bgset_7
de_modfit_84_bundle4_4s_south4s_bgset_7
de_modfit_85_bundle4_4s_south4s_bgset_7
de_modfit_86_bundle4_4s_south4s_bgset_7
The skip from 4 to 7 involves me putting test runs on the server while we were debugging some of the recent problems. Please let me know when stripes 84 and 85 begin throwing validation errors and I can take those down when the errors/runs ratio reaches ~10%.
Best,
Tom

| The Last Couple Days |
Hi Everyone,
As I'm sure you're all aware by now, the server went through a bit of maintenance the last couple days and now seems to be working normally. We had to clear out a lot of backlog workunits due to technical problems on our side. The bad news is that if you crunched workunits in the last two or three days, those workunits may have been deleted before they were validated, meaning that you might not be getting credit for them. The good news is that the server is working again and that we have taken precautions so that this won't happen again in the future.
Apologies for any inconvenience this may have caused. This caught us by surprise just as it caught all of you by surprise, and know that we will always try our best to communicate with you all when these sorts of things happen.
Best,
Tom

| MilkyWay Maintainance Continuing 2/2/2021 |
Hi Everyone,
The MilkyWay@home server will continue to experience maintenance outages today as we work on resolving the problem with the transitioner. Again, thanks for all your patience. You can check the status of the server at any time at https://milkyway.cs.rpi.edu/milkyway/server_status.php.

| Milky Way Maintainance 2/1/2021 |
Hey Everyone,
The MilkyWay server will be going down from 4PM today until midnight. After this outage, we should have the server up and running as normal, and the workunit generation issue will hopefully be solved.
Best,
Tom

| MilkyWay Workunit Generation Outage |
Hello Everyone,
MilkyWay@home is experiencing a temporary outage of the stream_fit_generator and the nbody_work_generator. You can see the status of the server here: https://milkyway.cs.rpi.edu/milkyway/server_status.php. This outage means that you will not receive new workunits from the server. You may receive jobs for validation, but those tasks will begin to slow down as workunits finish validating.
I have spent some time tracking down the problem, and I think that I know how to fix things. However, I need to make sure that my proposed fix won't accidentally break anything else, which will take some time, especially since it is the weekend. I would expect the workunit generation to remain down at least until tomorrow afternoon. I will post an update as soon as we know more.
Apologies for any inconvenience that this issue caused. Thank you to the people who let me know that there was a problem. As always, we appreciate all the time and effort our volunteers have spent on this project.
Best,
Tom

| Finally recovering from hard drive crash. |
The crash was so bad that the database could not be repaired. The first non-corrupted backup was 2 days old. Restoring from there seems to have worked but there are probably issues since it will be out of sync from results that get returned.
I pushed the deadline back another 4 days for any outstanding WUs to give people time to return them, but anything issued 2 days prior to the crash will not be in the database so I am not sure how that will play out.
Sorry for the inconvenience!
