[QUOTE=unconnected;431012]I've cracked several easy composites and now stopped at i2132 C167 which resist 7200@43e6.[/QUOTE]

Bump. ECM seems sufficient to start GNFS on a C167. Anyone willing to search for a poly?

Certainly. I'll post it here; 3 GPU-days at minimum. A GPU-week is probly about right, so someone else ought to consider a run too. I'll run starting at 200k.

I searched 200k to 4M with stage 1 norms varying from 2e24 to 3e24 (with no appreciable difference in rate of stage 2 hits produced).
Two polys close in score:

Score of the first one is 5.02e-13, while the second is 5.00e-13.

I've posted a request to NFS@Home to sieve this term, possibly by 15e(?)

14e is plenty potent enough to do anything up to low 170s, but NFS@home will decide what is best for their queues.

Edit: sorry, you knew that, just saw your post commenting the 15e is running dry.

C151 from i2134 is ready for GNFS. Any volunteers?

Here is a poly to consider. Is this too small of a job for NFS@Home?

[QUOTE=unconnected;433506]C151 from i2134 is ready for GNFS. Any volunteers?[/QUOTE]

I'll take this job. I can put 3 cores on the sieving. Shouldn't take more than a month or two to complete.

C180 @ i2135
 

2^3 * 3^2 * ... * C180

t40+ (320 @ 11e6) - no factors found.

I'll run some curves on this.

t50 (7200@43e6) completed.
