I was reading the closed thread AP 26....

There was a lot of disappointment that this project was shut down after the initial AP 26 was discovered. I believe this was sometime in 2011....

It was a GPU project......

Is anyone familiar with the process on how this search started, what software is required ?? how do I go about searching for a larger AP 26 and/or AP 27??

Seems plausible that an AP 27 could be found with the advances in GPU's in the last 3 years..

Iain,

I've been doing more research on the software to do an independent ap 26/27 search...

Apparently, you are the man to talk to ....

Brian Little did a major update to the source code for AP 26 in 2013, with a 4-5 time speed increase over the original software,..... and he did it for Kepler hardware and Fermi based NVIDIA cards... see https://sites.google.com/site/mfl0pwww/files
Unfortunately, Brian only provided his source code on the website... I have no idea how to compile a piece of code... Can you compile the Kepler version for me so I can start a search??

Much thanks in advance.

Hi Neo,

I saw your post at the weekend, let me see what code I can dig up!

I also need to think about what the odds are for finding an AP27. I think from what we found there is about a 10% chance that an AP26 is in fact as sub-sequence of an AP27. Thus to find an AP27, we would need to do at least 10x as much work as the AP26 sub-project. The problem is that finding those additional AP26 costs more, since the larger the primes, the longer it takes... Of course, CPUs and GPUs have got faster since then too...

Iain,

Any luck so far?

If you are successful, perhaps AtP could use the program exclusively for 2-3 weeks to give us the first opportunity to find a larger AP 26 and or possible AP 27.... (u know, just for beta testing purposes ;)

The resources needed back in 2011 to find the ap26 would seem to be almost the same, as you pointed out, to what it would take now to find an ap27 due to software improvements and hardware power...

Perhaps AP29 already discovered?

see link below in the yellow "descriptive data" section

https://primes.utm.edu/bios/page.php?id=339

If this is the case, lets scrap plans for ap27 and start with ap33!!

Go AtP!

[Edited... it was AP9, not AP29]

Anyways, when I try to goto the primeform yahoo group, it's just a mess... I don't know how anyone navigates that page. my display settings must need fiddling...
