[QUOTE=schickel;240143]Not good. Looks like the server may have dropped a table. We'll have to wait for Syd to fix this locally....[/QUOTE]
Well the server is currently offline for maintenance.

Elf files appear to be fixed!

The factor-DB seems to be down since a minute. I hope I didn't shoot it down by reporting a composite factor of 11^203+4^203.

Edit: the DB seems to have recovered.

I added 1403633425066500143601563.

The remaining C155 is probably a =<4-way split.

I guess that too. I have reserved it on the [URL="http://www.chiark.greenend.org.uk/ucgi/~twomack/homcun.pl"]Homogeneous Cunningham Reservation page[/URL]. It has survived 600 ECM-curves at B1=11e7, switching to SNFS.

I wonder who will be the first to write a BOINC wrapper for a DB worker?

Only one is needed...

Question about sequences
 
This is a question for Syd really, since it deals with the backend code: if an aliquot sequence is uploaded and a connected worker factors the remaining composite on the last line, does the DB comtinue the sequence or does it only "discover" the continuation when someone looks at the sequence? (Sort of a DB Uncertainty Principle, if you will....:smile:)

I think that anyone wanting to BOINC-ify some DB tasks should do so only with tasks that require sufficient wall/CPU time (read: dozens of minutes), like GNFS > 95-100 and ECM > some threshold. The BOINC infrastructure does have its own overhead, too :smile:

That said, would using a BOINC infrastructure enable taking on tasks that one, or several, ad-hoc scripts of several hundreds SLOC cannot do ?

Congrats on your 68-74-split, Andi.
