Does anyone want GW_3_513? If not and it will fit in 16 gig of RAM & there is no real rush for it e.g. 14 days running at roughly 12 hours a day I might be interested in taking it on

Why don't you take GW_10_239 instead? It will be faster to post-process. GW_10_239 SNFS(241) vs GW_3_513 SNFS(248).

All tasks for which it is reasonable to use 14e fit in 16 GB of RAM - or in fact, pretty much always in 8 GB of RAM, unless the OS + other applications have a large footprint.

Sure I would be happy to take 10_239. The reason why I never thought of taking this is because the download size is almost double that of 3_513. Hence me thinking it would take twice as longs to process going by size.

Currently 10_239 is 12 gig Est. Pending Rels 177399 remaining & 3_513 is 7 gig. It was late when I was looking at 3_513 I thought all of the work units had been processed this is not the case hence the size difference.

The . DAT for 10_239 will be in the middle to late 20 gig range uncompressed.

Thanks Carlos for pointing that out to me & I had forgotten about the numbers in brackets

Thank you handy to know

What is the latest status of the sieving? The 15e statistics listed on the NFS@Home site seem a bit strange for this number.

I believe I can complete the LA if it's available but don't want to step on toes if someone has tacitly reserved it.

Do you still want GW_3_513? I can do it instead if you think it will take too long on your PC.

William (wblipp) proposed and did ECM on the number, I don't know if he also wants to do the post-processing.

I'll send him a PM.

Thanks. I'll wait and see if he plans on working it. There are other numbers I can post process on 14e if he's taking P58^5-1. I was just afraid this number was stalled.

Is it fully sieved? Maybe one of the NFS@Home mods can let us know?

I'll take the C169_HP2 number once it finishes up.

I'm running the LA and it should be done on Tuesday
