Prime95 version 29.4

[ET_]

Not quite a bug, just a request for comments.

I am using mprime for Linux 64, version 29.4b5

While setting up computers to get enough work for the next days, I used Option/Preferences and set "Days of work to queue up" from 3 to 15, expecting to receive some work. I didn't.
Then I selected the work to get and set it to 1 (TF-LMH). Nothing happened.
Then I chose Advanced/Manual Communication, answered Y to all requests. The program contacted the server, sent out the completion dates of what I had on the worktodo.txt (about 2 days of work) and stopped the communication. No new work was sent from the Server.
Then I tried Option 4 twice (Stop execution - Start execution). Nothing.
Finally I tried Option 4 (Stop execution) followed by Option 5 (Exit mprime), restarted the program and again Option 4 to (re)start the computation. I didn't receive the new work from the server.
At this point I even tried to select again Manual Communicaiton. Nothing.

Now I have "Days of work queued" set to 15, and the last exponent expiring on January 8. 15 exponents on the worktodo.txt file, 1 worker, 1 thread selected.

Is this the expected behaviour?

Nice! I'm seeing about a 6% speed up!

One thing I noticed while upgrading some of my machines: while the download page is SSL, the download links are just HTTP. Software links should definitely be SSL, to avoid any "Man in the Middle" injections.

When I started with PRP-CF, most assignments were really small and I remember that it maxed out at some point such that it was only able to run a few minutes without web access. This seems to be a hardcoded upper bound; maybe there is an option to increase it?

EDIT:
As Luigi pointed out, there is MaxExponents=n for prime.txt.

When you don't trust those (securely transmitted) checksums on the download page, there is no need to trust in SSL.

Yes there is. undoc.txt.

The program will restrict how many exponents can be added to worktodo.txt.
To override this, change prime.txt:
MaxExponents=n

True... But how many Winblows users know how to run a SHA256 checksum?

Just use standard PowerShell:

get-filehash your_filename

You can specify a different algorithm with the -algorithm option, but -algorithm SHA256 is the default

Look in undoc.txt for a limit on the number of exponents that can be queued up. Maybe I called it "MaxExponents" or some such???

That is, if they use "Exblower", to stay in tone with you. If there is a single program that we have to pick from a list of programs we hate, then that program is Windows Explorer. There is no other stupider file manager. Fortunately, most of us (i.e. people who use computers for other things than office, word, email, etc., but also do some programming, playing some games, hunting for some primes, etc) use different file browsers. "Total Commander" from Chris Ghisler is quite a good choice, and for that, playing with CRCxx, MDA5, SHAxx, etc, is piece of cake, in fact if you have the file with the right extension in the folder, you can get automatically kicks and punches in the nose if the files are corrupted.

You should update the GIMPS home page to say that a new version is available. Not everyone reads the forums. By the same token, the fact that the P-1 stage 1 format isn't backward compatible should be noted on the download page.
