So long and thanks for the fish!

Feature requerst for the factor 3_2 program
 
Would it be possible to include a benchmark option ? One that ran for about 10-15 secounds, so one could easily see how fast the different cpus manage to run the factoring code.

M3321928777 no factor from 2^66 to 2^68.
I will not take that exponent further.

Up to 66 or more? :whistle:

M3321928921 no factor from 2^66 to 2^67.

Time: 19645 secs.

This on one Athlon MP1900 (1.6 Ghz). Since this is nearly twice as fast as my p4 2.4 GHz, i think I will crunch on the Athlon.

So I would like to continue to reserve M3321928921, and I will see how far I take it.

As I wrote in another post, I'm going to compile an optimized version for Pentium IV. So far the version is more suitable for Athlons.

Try working the same exponent on different CPUs at smaller bit depths: i.e. from 1 to 50 bits: it should work as a benchmark.

Anyway, I'm working on a benchmark page.

Oki, I will try that. Thanks !

M3321928319 no factor from 2^69 to 2^70.
M3321928319 no factor from 2^70 to 2^71.

Im continuing to 72bits.

Carlo strikes again.

He reserved 3321928777 and is going to take it from 67 to 72. :showoff:

As for me, I take the following:

3321929929,65,66
3321929971,65,66
3321929987,65,66

My hard drive crashed! :cry:

The crashed one was a 2.4 GHZ P4. I am currently on a PII. It sustained a smaller problem abd had to restart. I tried to ask Luigi how to recover the 43.5% I had lost and he said to go to status.txt and type 'Factor3_2 -r' in. I tried it and it didn't work so instead of PMing him again I'll let everyone know how.

Thanks!

Copy status.txt to the 'new' computer and put factor3_2 in the same place (along with the .dll's). [B]Then[/B] type factor3_2 -r
