I'll take W_2_785 if it's still available.

ETA for W_2_785 is Monday.

I'll take GC_8_262 next.

I'll take GC_10_237 next.

[QUOTE=RichD;368558]I'll take GC_10_237 next.[/QUOTE]

After numerous filtering attenots, I had to take target_density down to 80 before it would build a matrix. TD=84 failed.
It's running now. ETA 161 hrs.

I'll take GW_8_262 next.

186 hours for a 12.8M matrix on a moderately busy i7/2600K: log at [url]http://pastebin.com/i8c82anE[/url]

I do wonder whether 31-bit large primes might be sensible for these SNFS-240 numbers; we're having to sieve a long way at rather low yields and rather high duplication rates to get rather large matrices.

Taking GC_9_248
