CUDAPm1 runtime scaling, and comparison to CUDALucas
 

Timings for an assortment of exponents are tabulated and charted for reference. Note, only one trial per combination was tabulated, so no measure made or indication given of reproducibility run to run for same inputs. See the attachment. This is a somewhat different way of looking at test speed than the GPU Lucas-Lehmer or trial factoring performance benchmarks at [URL]http://www.mersenne.ca/cudalucas.php[/URL] etc. There is no P-1 factoring performance benchmarking data posted at [URL]http://www.mersenne.ca[/URL] to my knowledge.

Software for managing Mersenne hunting software
 

The attachment contains a summary grid I put together for software that helps run one instance or multiple instances of factoring or LL testing software implementations. Please comment:

1- Which did I miss entirely

2- additions, corrections, suggestions

Ancestry of available software
 

Some software was derived from other earlier software (or multiple others). The attached crude diagram shows my understanding of ancestor/descendant relationships, gleaned from sources such as source code comments/credits, and web pages. It's intended to show ancestry of code, not concepts. Code shown without connecting lines is believed to have been developed independently. The thin line between lucdwt and prime95 is intended to represent prime95's adverb "loosely".

As usual, please respond with any additions, corrections, comments.

If you put submitting spiders in the graph, then a mention of Misfit won't hurt...

Ancestry graph
 

Meant to include Misfit earlier. Oh well.

Ancestry updated
 

Changes since last time:
Switched to a better draw program, reformatted somewhat in doing so;
Added glucas

Available client management software table updated
 

Added "Mersenne manager". (which is actually separate programs, for tf, and for LL/DC.)

Available mersenne prime hunting software table updated
 

Added row for PRP testing in part 1,
updated and extended various data in part 2 to reflect recent software updates, etc.

Utilities for GPU computing etc.
 

Here are some things I've run across that I found useful or interesting, or have seen recommended by others.

Versions stated for each, and links, are current as of Jan 23 2017.
Subject to change without notice, no warranty express or implied, availability versus OS etc will vary, don't look a gift horse in the mouth.
