Time for another team job. After a lot of heavy lifting from bchaffin, 4788 has stalled on a c162.

A lot of sieving will be done by RSALS, but if you have some spare cycles, every little bit helps...

Sieve specialq on algebraic side from 20M to 90M with siever 14e. Aim for about 84M raw relations.
Post-processing will be done by Batalov.
28 Dec 2010 Post-processing started, ETA 29 Dec 2010
30 Dec 2010 Post-processing complete! c162 = p63 * p100

Reservations:
Code:
20M - 50M   RSALS
50M - 80M   RSALS
80M - 90M   RSALS
90M - 95M   RSALS
95M -100M   RSALS
Relations so far: 78M

The poly posted by jrk yields ~1.4 relation per q value over a range of 1000 q values starting at (r&a)lim/2.
For a 30-bit large primes task, on average, RSALS clients can sieve the bulk of a range of 30-40M q values, split in WUs of 10K q values, in 3-4 days.

Will you also be able to handle the post-processing?

schickel: RSALS relies on external contributors to do the post-processing. Is there somebody interested in Aliquot sequences willing to do the job ?

AFAICS, the best poly posted here so far was by jrk, indeed.

Reserving 50M-80M for the RSALS grid
At the current rate of crunching, I'll start "C162_4788_2602" by Wednesday.

Pls send me a PM when needed, because I may not notice/follow specific threads. (But I'll receive a PM for sure.)

I've just added "C162_4788_2602" to the RSALS work generation infrastructure. For now, WUs will be generated from q=50M to 80M.

At the time of this writing, nearly 5/6 of the 50M-80M range have been distributed to clients, with more than 1/5 of the corresponding results returned, yielding ~6M raw relations.
I'm therefore expanding the RSALS reservation to 80M-90M

So, do we need a thread for this job to co-ordinate other contributors, or will RSALS be able to do it all?

20M-90M will probably be enough, so if RSALS are willing to do it all, that's fine.
