I've completed 1.25*t50 so far. I recommend moving to t55-optimal curves.

No factors after 10000@3e7; another 10000@3e7 is running, but I think it's nearing time to start sieving.

That's close to a t50. In addition to these, I've done nearly 2/3 of t55 (4857 curves at 26e7). I agree that it's time to sieve.

On the RSALS grid, the current sieving (SNFS difficulty 243) is coming to an end. I'll queue "C160_4788_2715" afterwards.

In the team sieving, it would be great if the 80-86M range was reserved starting from 86M and downwards, so that in case nobody reserves all of it until all WUs for 20M-80M are distributed by the RSALS server, I can easily expand the range

I can do finishing for a change (need to test the new 16Gb computer; granted, not all memory will be used, but a test is a test is a test).
