Cool Benchmarks

Hi everybody!

I am reworking productivity and testing pages on FermatSearch (http://www.fermatsearch.org/productivity.html ).

I'd need data (specifically, k/sec) for mmff working on Fermat numbers, specifically for the following ranges:

N = 28, 32, 36, 40, 44, 48, 54, 60, 80, 100, 150.

It would be fine if we could fill up the following table:

Range: k=1e15 - 1.1e15

Code:
        ----------------------------------------------------------------------------------------------------
	|   28   |   32   |   36   |   40   |   44   |   48   |   54   |   60   |   80   |  100   |  150   |

Remember to find the optimal GPUSievePrimes for each n. Do you need data for GTX 460?

        ----------------------------------------------------------------------------------------------------
	|   28   |   32   |   36   |   40   |   44   |   48   |   54   |   60   |   80   |  100   |  150   |

Note that currently mmff only works for k>=224 and k*2n+1 <= 2188, so for n=150 you can only do:
FermatFactor=150,174,188
which only takes 16min on a GTX 460.

The highest working n=159 only works for:
FermatFactor=159,183,188
which takes 40sec.

The highest working n for which there is still work to do < 2188 according to: http://www.fermatsearch.org/stat/done.php
is n=146:
FermatFactor=146,3e12,188

Thanks for reporting the GPUSievePrimes too. I'm fairly certain that the optimum setting won't change much for each Nvidia model.

Note that timings will change as k increases. As the bit size of the factor increases, wider multiplications are required.

Let's specify a specific k range to benchmark - something representative of current reservations (like 1e15 to 1.1e15).

Ok, I'll need to rerun test tomorrow then at new k if we agree on 1e15-1.1e15.

Btw GPUSievePrimes have a range that gives the same speed and the range is longer for higher n. For n=150 basically 600k to 1075k give about the same speed.

I agree.

The first post has been updated.

Thanks ATH.

Here's my GTX 480. I didn't optimize GPUSievePrimes, but instead let it just use the mmff-0.25 defaults.
