Mersenne prime hunting software (with emphasis on utility for current & future wavefronts)
Part 1 Software possibilities vs. approach and device type Approach Device Type Intel, similar CPUs other CPUs NVIDIA GPU AMD GPU Intel iGP Trial Factor Prime95, mprime, etc ? MfaktC Mfakto ? P-1 factor Prime95, mprime, etc ? CUDAPm1 ? ? PRP test Prime95, mprime, Mlucas Mlucas? GPUOwl ? LL test Prime95, mprime, Mlucas, etc MlucasCUDALucas clLucas (gpuOwL) ?* * GpuOwL ran on an iGP equipped i7-7500U test system; throughput was ~25% of the coinciding drop in Prime95 throughput; possible pilot error (me)?

(May add in future, a list of software of which I concluded a sufficient number of criteria are not sufficiently met to include in the table. Such listing should not be considered disparaging, libelous, etc. only a judgment that it is less suitable by a sufficient margin to exclude. Consider it encouragement to adopt additional or different features, or recognition the listed software serves a different purpose. Purpose of list would be to reduce repeat suggestions. May suggest areas of change or addition that would raise chance of user acceptance.
