The server crashed due a memory leak. The database was corrupt so resorted from todays backup, it was expected but need to investigate which was causing this. wanted to fix this in 3d but came earlier.

There was a lightning bolt on 1/4/2024 in the night that damage (e.g. they broke) many electrical devices in the area (1Km^2).
Internet connection were restored only in the morning (as provider is at 200m distance of the server and it was damaged too).

Even if the server is behind a power supply, it get in non operational state (e.g the data disk was disconnected), maybe due to the heavy electrical current it passes onto the battery power supply.

Every disk of the server were un-mount from it and tested in another machine and all data were ok, even if the server did not boot properly.

Now it is running in emergency mode (e.g. it need a manual start up, so if it restart from eventual current blackout, it will no boot) and I will monitoring if all is going right.

During the weekend, I will work on fix it, so the server will be disconnected for some times during the day.

Remember that if the internet connection is on and the server is off, you can see some message here: http://boinc-status.multi-pool.info/ about his state.

Please, remember to set up a backup BOINC project in case of emergency. Thanks.

Part 2 of the 10²¹ search will be finished, for the most part, today. There are still ~2000 unfinished WUs which can take up to a couple of weeks to complete, depending on individual participants processing them.

Part 3 of the search will look for amicable pairs where the smaller member of the pair has its largest prime factor between 10¹¹ and 10¹⁴:

m=m1*p, 10¹¹ < p < 10¹⁴

There are too many primes larger than 10¹⁴ (all primes up to 5*10¹⁹ need to be checked), so they will require a different approach and a new application when the time comes.

Most of the participants have already started getting part 3 WUs. The new work units will require ~2.5-2.7 GB RAM on CPU, and the same amount of RAM on GPU (for GPU applications), so the minimum requirement for GPUs will be 3 GB RAM.

Right now I don't have an estimate on how long part 3 will take because I haven't accumulated enough statistics yet, and I haven't even finished generating all WUs for part 3.

BOINC is a finalist for an notable award, and needs your vote (*by Sunday)

The World Summit on the Information Society (WSIS) (https://www.itu.int/net4/wsis/forum/2024) is a United Nations-sponsored initiative aimed at harnessing the potential of information and communication technologies to build inclusive and equitable information societies worldwide. BOINC has been nominated for a prize at the 2024 forum (https://www.itu.int/net4/wsis/stocktaking/Prizes/2024), and has passed initial hurdles; the next and last step ("Phase 3") requires public votes. The award would be a very nice boost and validation for BOINC and all our projects; if we can get our communities to vote, we should have a decent shot at this point...

Voting is pretty simple, takes just a few minutes; instructions are here: https://docs.google.com/document/d/1x9Xi3tq7Y9dlDD0Xb0Ul0yYCXct5pDqIqssqARxvrXg/edit.

(*The deadline for votes is Sunday: 31 March 2024, 23:00 UTC+02:00)
