Basically Louie P-1'ed a range of 400000 n and produced 151 factors.

0.3775 factors per 1000 n-range

11600000 11770000 engracio 30
12000000 12020000 engracio 8
11400000 11600000 engracio 51

E P-1'ed a total range of 390000 n and produced 89 factors.

0.228 factor per 1000 n-range.

Louie used a B1=95K with B2=B1x11.5
E used a B1=75K with B2=B1x11

Basially Louie spent close to 30% more processing power per k/n pair, yeilding a 65% increase in factor probability.

Very interesting, E you might want to try higher bounds say B1=110k and if you are not limited in memory and have dual channel try upping your B2:B1 ratio. I wouldn't go much beyond 14.

B2=1500000

Are you still running those MPX's?

The most important point to remember is a little P-1 is better than no P-1 so as long as we are not passing ranges...

Vjs,

Yes on the MPX but they are now sieving and dying slowly, had to use their memory and to increase and make it dual channel the memory on the Xeons and a Pentium D915 oc'd to 3500 mhz. Probably could get a few more mhz but did not want to spent money on memory and better cooling.

Did not know you guys were going to break it down and throw off my galactic wag. Portions of my range were skipped due to the random fluctuations of the prp. I know I skipped a few factors.

I really just wanted to know how Louie was able to complete those range so quick. One quick answer was he had more machines to crunch. doh!

I'll slowly increase the B2 and see if they really make that much difference. My P1 machines are all Intel cpu's and I try to have at least 1gb of memory while factoring. What is odd is I have P4 2.8 with only 512 memory with 452mb allotted, max memory Prime95 would let me allocate. It can crunch a factor every two hours but my Xeon 3.1 could only crunch every two and half with 560mb alloted per instance.

Most of the time it is not used. Ummm.
