You can use my real name Youcef Lemsafer for the credit.

Will do. Thanks for taking on the task.

Please email me (paul@leyland.vispa.com) when you have results as that is much the most reliable way of getting my attention.

You're welcome.

OK I'll do both I'll post the factors here and I'll send you an e-mail.

Amusingly, I think I independently edited the reservation to use your real name, right in the time frame of your message, without noticing it

Pascal is the most interested in OPN factors, followed by me. We both read here.

Just a quick advice. 7-8 days before the NFS@Home challenge (starts at 2015-03-15 00:00 UTC ) can I advice not downloading any files from the server for post-processing. It is expected a lot of bandwidth usage by the clients to bunker work. When the time comes I will warn you guys again.

Thank you.

Taking C_2_785

YuL · 2015-02-20, 10:34

Regarding GW_5_346.
It appears that the sieving is over but the number of relations 200M seems a bit
insufficient. For a 31 bits job aren't we supposed to aim for 210M-220M relations?

debrouxl · 2015-02-20, 10:45

Correct, I have expanded the ranges for five numbers currently under sieving

Victor, have you started post-processing C_2_785 ? If you haven't, the range might be expanded a bit, in order to obtain ~10M more raw relations and be more confident that filtering succeeds - though 210M ought to be enough for SNFS 239, assuming redundancy rate is normal.
However, the post-processing time reduction from a smaller matrix achievable through those extra relations wouldn't make up for the delay in post-processing that number.

I've filtered C_2_785 successfully with Target_Density 105, matrix was 11M-ish (not sure exactly, I'm away from the computer). So I don't think 10M additional relations are going to make much of a difference. I haven't started LA on it yet, but I'll start that Sunday evening when the current task finishes.
