I'm not running L1286; go ahead Victor.

swellman · 2014-10-11, 15:40

I'll reserve C175_123_73 if it's still available.

Thanks.

GC_8_266 factors as:

Took 128 hours with 4 threads and density of 128. Factor found on the 9th dependency.

I'll take GC_3_506.

wombatman · 2014-10-21, 15:21

At 16.3% complete, approximately 102 hours left on 4 threads at density of 128.

Eta: what happened to the code function? It used to automatically truncate width as needed, now it seems to be broken. Something change behind the scenes?

reserving GC_7_282

L1286 should be ready tomorrow.

[edit]
Forgot to ask the last time, I've had several:
"error: corrupt state, please restart from checkpoint" with L1282 and 1286. I restarted them with -ncr and all was fine again. Could this be memory or memorycontroller instability (it did pas a round of memtest, but that doesn't guarantee 24/7 stability under heavy memory load) ? Or could it be running out of memory when making a checkpoint (it's using 13.2 GB on a 16GB machine)?

Msieve is very good at stress testing memory. It can find faults that other programs can't. It does sound like you have a hardware problem. Has this pc always done this or is it new? Does it need dedusting?
