I have NFS and ECM running against the 2858:c120. It should be finished by tonight, if no one else goes ahead and factors it.

The machine should automatically update the db, so I might not post anything here in a timely manner, if I haven't noticed the completion.

It traded for a c129. Working it...

Actually, I underestimated - it's already filtering...

Sorry, I wasn't more clear earlier when I wrote, "Working it..."

edit: Hmm, had some overlap between a couple machines and it looks like a huge percentage of duplicates.

Might be back to overnight. Maybe you can get yours done before mine...

Starting P-1/P+1/ECM on the c143...

Edit: P-1 @ 1e9 done. P+1 @ 1e9 done. 1000 @ 1M done. Now ECM @ 3M

Edit 2: Factor found:

Code:

GMP-ECM 6.4 [configured with GMP 5.0.90, --enable-asm-redc] [ECM]
Using B1=3000000, B2=5706890290, polynomial Dickson(6), 4 threads
Finished 729/3000; avg s/curve: stg1 5.309s, stg2 2.105s; runtime: 1698s

Run 729 out of 3000:
Using B1=3000000, B2=5706890290, polynomial Dickson(6), sigma=3028862197
Step 1 took 3764ms
Step 2 took 1564ms

I put 7600 ECM curves @ 43M into yoyo@home queue and send then with high priority.
