Does it fit to the file you posted before?

Someone could try aliqueit copying in the factors from the db. Could be a little painful but only necessary for >~25 digits.

How can you insert factors when the webinterface is detached from the backend, dude?

...so you think it is a good thought to insert into a database that is being repaired? You will be inserting into "write-only memory" :-)
If Syd made his DB conventionally, then there are (at least) two instances, production and test (which will be flipped when one is repaired and then sync'd).

Inserted a few more lines, but don't be surprised when they will be gone after the database repair.

P.S. And there, Syd figured that he left a door open for you. It is now shut.

Anyway, it is line +101, a c95.
In line +109, a c109. Running NFS.

)

+216 went under size 90... Now I can sit back and simply watch. (Before I was firing parallel ecm helpers)
went under size 70... quite a view
went to size 33, bounced a few times
acquired 2^4 * 31 (with some 3's)
back to size 102 and climbing

Why are you doing gnfs on a c90?

Batalov · 2012-05-12, 23:37

Because it takes equal amount of time, maybe slightly faster by gnfs.

bsquared · 2012-05-12, 23:41

Do whatever is faster for you - it just surprises me that c90 is faster by gnfs. For me on intel chips, the crossover is more like c95, even with asm ggnfs.

Passed the low point of c33 and now climbing.
