This appears to be an excellent compilation. I hope it will always be easy to find. Many things here get buried in the mix rapidly.

Thanks. I've scattered bread crumbs (pointers) here and there in the forum. I find it useful to link back to these posts which saves me typing when responding, and may lead people to more. A web browser bookmark to the sub-site map page works too. It grew so big a post or two at a time that I created that for my own use in quickly finding what I knew I had already written.

Sub site map to the reference info, and also discussion threads like this one: https://www.mersenneforum.org/showthread.php?t=24607

While I understand the forum is a good place to discuss such things, much more comfortable than the discussion pages of a wiki, a forum is not a good place to store reference material (except perhaps in closed threads) : it gets buried in the discussion about its elaboration and adjustments.

As usual, useful work. Thanks!

A suggestion/addition: rather than "squat", nomenclature which has been used previously to describe this is "working `off-the-books`".

Edit: Oh, and also perhaps, add "Wave-back", AKA "Stragglers".

I would suggest that you look at the wiki for other ideas.

Also, miletsones acknowledge DC milestones, proving a prime is the Xth MP, and all exponents tested once up to a given MP

This is precisely why I have collected the materials into a blog space that xyzzy offered me. The dilution by discussion posts here has so far been minimal and manageable. Discussion threads here are only ~2% of the total thread count. Posters are warned elsewhere that discussion posts in reference threads may be moved or removed (deleted) without warning or recourse. In the event that I become unwilling or unable to maintain it at some point, Xyzzy can close all the reference threads. I suppose as moderator of this tree I could close and open them when I edit, but so far it has worked rather well to leave them open.
Anyone with the knowledge and desire to create a GIMPS reference wiki is free to create links to these reference posts. I plan to not do so.

The location of the GIMPS reference posts site map is unlikely to change; bookmark it. https://www.mersenneforum.org/showthread.php?t=24607 It is now book size, with over 200 reference posts.

If you want to overhaul any post in that thread (except the links to M40), a super-mod can take your revised version and sub it in for PrimeMonster's.

Thanks for the invitation. My first reaction is, not at this time. Maybe someday. Meanwhile, I suggest if PrimeMonster is no longer active, appending a pointer link there, over to my reference info here which is being actively maintained and extended, specifically, to https://www.mersenneforum.org/showth...922#post521922

So why not using my Prime Wiki, the reanimated MersenneWiki with those old data and pages around GIMPS.

Daily backups (holding for two weeks) for the database are set.

Other advantages:
- history of any page edit
- create your own pages naming like you want
- linking to other pages or externals are easy done
- many programs are described in the Wiki but need some updates in information
- many pages for Riesel, Proth, Williams, Carol/Kynea, Leyland primes are currently available and should become more and more holding the history of search spreaded all over the internet (e.g. see Carol/Kynea base 2)
- Math rendering available
- upload/display of PDFs is available

A clear categorizing should be done first for your pages although most of your topics are in the Wiki.

I created worktodo.txt.....
However I do NOT know what goes into config.txt ... Thanks

THEN when I ran this:

from google.colab import drive
drive.mount('/content/drive')
!chmod 777 '/content/drive/My Drive/gpuowl'
!cd '/content/drive/My Drive/gpuowl' && LD_LIBRARY_PATH="lib:${LD_LIBRARY_PATH}" && chmod 777 gpuowl && chmod 777 worktodo.txt && ./gpuowl -use ORIG_X2 -block 200 -log 120000 -maxAlloc 10240 -user petrw1 -cpu colab/K80

Drive already mounted at /content/drive; to attempt to forcibly remount, call drive.mount("/content/drive", force_remount=True).
/bin/bash: ./gpuowl: Is a directory

Please and thanks
