is a mathematical research project that uses Internet-connected computers trying to solve Sierpinski / Riesel Bases up to 1030. You can participate by downloading and running a free program on your computer.
The project is in collaboration with the Mersenne CRUS project.
The server is running on a private computer in a VM.

User of the day
I am cruncher from Czech National Team
I manage http://stats.czechnationalteam.cz/.
planned downtime tomorrow and today for router update
Tomorrow I will move the server VM again to the new server. This could take up to 1h.
Today the router must be updated to the latest firmware, this should take around 10min. (done)

Server/DB crash / Hardwarefailure
Looks like a broken RAM / hardware crashed the hole server, the downtime was 15h. I have moved the VM to my old server, this was stable but have now some errors in Linux, if you fix something another error appears. The win log still telling me broken hardware but need to take time to maybe reinstall OS, testing RAM etc.
You will now getting a lot of download errors because the input files were deleted while the WU was already finished. Around 1h after my last backup yesterday the server seems to be crashed.
Iam thinking about to let the BOINC VM on the old server, no updates (except firewall), less OS crash impacts but slower.
Apologies for the outage.

SRBase - 7 years review
The project has passed the seventh year.
Compared with last years the following process was made:
2014-2015 - 1 base solved, 314 bases unstarted
2015-2016 - 5 bases solved, 297 bases unstarted
2016-2017 - 5 bases solved, 282 bases unstarted
2017-2018 - 1 base solved, 264 bases unstarted
2018-2019 - 6 bases solved, 218 bases unstarted
2019-2020 - 4 bases solved, 120 bases unstarted
2020-2021 - 3 bases solved, 101 bases unstarted
in total - 25 bases solved, 101 bases unstarted
A last minute server crash before end of the year due a bug in the AMD Andrenaline 21.10.2 driver updated last month caused some troubles. An update to 21.12.1 was made.
There are no CRUS goals for 2022 available at the moment but will be published soon.
I will upload more work today. There are still some download errors left but fixed it with a change in max_errors_results

Server /database crash
Back to home and the server restarted. Anyhow the AMD driver chrashed the hole system. Never had this before. Also the file system needed a repair. The backup from 10am was restored. Let me know if you have lost some work. Still having trouble and checking.
The error rate will increase, ignore these.

I need to install some updates. This should take no longer than 30min.
