[QUOTE=chris2be8;295281]Thanks.

NB. [url]http://www.oddperfect.org/[/url] still points to the old address.

Are you sure? I changed these a couple of weeks back. You might be getting an old copy from your local cache, or I might have missed some.

jrk has finished post-processing 751^79-1 to:

Before I delete it from the server, is anyone else interested by the massively oversieved dataset ? :smile:
This one features ~50% oversieving, the largest oversieving percentage ever on RSALS, because for a while, after entering the task as 30-bit LPs, I aimed for a target number of 110M-120M raw relations... but it was actually a 29-bit LPs task...
I immediately made RSALS stop generating new WUs, but at that point, enough WUs for ~89M raw relations had been generated...

I had to post the factors to the DB because it still said C185 (they weren't added yet).

I'll do 557_73_minus1 while C147 is not finished. Maybe some other phi(73)s later.

I've got 593 reserved in the "BOINC NFS sieving - RSALS" thread but it looks like 599 is still available.

It was an old copy in my cache. It must have been there for several months though. Should Firefox have checked the date the page was last updated?
