More than one B2 bound per kn-pair?

[Joe O]

I tried to set up my computer to do the tests. It finished overnight, but the results were really peculiar, I must have screwed things up somehow.

Should I try again, or just forget about it? I have the feeling that, while architectures could have different timings, Stage 1 and Stage 2 are proportionately the same when you're comparing the same B1/B2 values.

Stage1 might be proportional to the raw speed of the processor, but B2 is heavily dependent on memory. How much memory do you have on your machine? What is your processor speed?
Just run with B1=130,000 and B2=2,000,000.
Thanks.

Apologies, I didn't see this until just now. It's running now.

Edit: I'm running it with maxmem=1200MB

With maxmem=1200MB Stage 1 takes 3hrs25.5min and Stage 2 takes 2hrs51min

Because of a message from vjs

dual-core Pentium-D 2.8GHz. 2Gig of RAM with 1200MB allocated to Prime95.

Extrapolating from the timings you both have provided, it looks like:

B1=130,000 and B2=2,200,000

should be optimal.
Jasong, you should get 3 runs per day.
Glennpat, you should get 6 runs per day per core.

changed.

I started running the new bounds a couple of days ago. The stage 2 time went to 1 hour 48 minutes.
