After I've sent you my chunk, overnight, these two were found, among others:

Running on 5 cpus at the moment; I'll add more as other jobs finish. By when would you like people to submit their results?

I will fire this up on 8 cores, and some GPUs as well. Running in the 90M range for some and probably try 500M for some others just for variety.

Thanks for the extra firepower; give it a month at most.
I should hasten to add that I can be emailed results directly, but try to keep them under 2MB or so. Otherwise you can use sendspace or rapidshare if there's no other private upload space available.

One of my clients is giving a crap line after every poly for one value. The latest selection:

The client decrapified itself, now working on 500174136 without any crap warnings.

I guess there is a big difference in speed depending on the range you are searching and what is found?

It is amazing the hashtable size from different 50k runs, 6552 for one, 55104 for another, 41546 for another, and 16367 for another. All taking about the same amount of time to run.
I'm now running svn 564 and will let you know if I see any more crap. Jeff.

Well, the number of leading coefficients (A6's) searched goes down as the size of those A6's goes up (this optimization is to favor A6 values with lots of small factors, to boost the projective root scores of the resulting polynomials). So there is a time difference based on where in the range you start.
The size of the hashtable depends on the number of 'other' entries computed at the beginning of each A6, and on where in the specialq range the current specialq lies. Last fiddled with by jasonp on 20110428 at 12:16
