Hey Xyzzy, did you manage to start L1378?

[QUOTE]Hey Xyzzy, did you manage to start L1378?[/QUOTE]We have Msieve compiled and the files downloaded. We hope to start on it in the next hour or so.

:max:

I'll start L2225B a little later today.

11_348_plus1
 

Some nice chunky factors:

[/CODE]

Please reserve 5_492_plus1 for me. Thank you.

I'll postprocess 11_327_minus1

L1378, 8 threads on an i7 3770, ETA ~90 hours - sounds right?

We'd like to try more work if there is any available. We have four boxes open ATM.

Something is not right. I'm running F1887 for RSALS and it is a GNFS(162) compared to yours that it is GNFS(163), only one digit higher on difficulty, and my ETA was 68 hours. My machine is a core i5 750 and your machine is twice as fast than mine.

Available you have 1886503_37_minus1 and F1761.

Mike's number may have been (relatively) undersieved. With a bit of deliberate effort, it is possible to construct an enormously hideous matrix for even the easiest of the projects. In other words, on the same number, you can build matrices with runtimes differing as much as 3x. Or more.

Also don't assume that the shear amount of relations will automatically translate into something being easier or harder. There's a correlation; and there are outliers.

What are your guys matrix sizes and densities? "GNFS(162) compared to ... GNFS(163)" is not the answer.

Looking at the logs of SL1482 SNFS(206.5) and SL1497 SNFS(208.6) the latter has less 13.3 % of unique relations and LA took more 4.12 hours.
