Timings for an assortment of exponents are tabulated and charted for reference, and other considerations like memory requirements also, for the NVIDIA GTX480. Note, only one trial per combination was tabulated, so no measure made or indication given of reproducibility run to run for same inputs. Where issues were encountered they are briefly identified. See the pdf attachment.
CUDALucas run times are also shown here, for consideration of how the CUDAPm1 run time scales with exponent, since the point of running CUDAPm1 is to maximize savings in total Mersenne prime hunt search time by efficiently finding factors that eliminate the need for a primality test or two or more.
This is a somewhat different way of looking at test speed than the GPU Lucas-Lehmer or trial factoring performance benchmarks at
http://www.mersenne.ca/cudalucas.php etc. There is no P-1 factoring performance benchmarking data posted at
http://www.mersenne.ca to my knowledge.
Data now span 10M to 700M
