recovered from server crash

Veröffentlicht: Dezember 19, 2016, 4:26pm CET

Last night the power supply of the YAFU server died. I could attach temorary a different one and restart the server. But the database didn't start and the DB recovery also didn't worked.
So I made a backup of the project and the project DB and started a 2 month old snapshot.
There I restored the backup and DB backup and now the server is running.
I hope without problems.

In the boinc server a bootstrap style is currently under development. For test purposes I deployed it here in yafu, just to see how it looks like.

No unreserved Aliquot Sequence below size 131 anymore

Veröffentlicht: August 24, 2016, 2:54pm CEST

I reserved all unreserved Aliquot Sequences with size=130 for the project. There is now no unreserved sequence below 131 anymore. We increased many sequences in it's size and were also terminated some.

We got a little bit stuck on the very big numbers. Only 2 have 16 or more cores in their system and run the YAFU-16t application.

But currently there is also enough work to do for the standard YAFU app.

Much thanks for your contribution!
