John,
I would also like to give you a big Thanks for the time you took to help get this "newbie" started on PRPnet, and all the posts you diligently update to keep the PG community up to speed, and on upcoming projects, and issues. Best of luck on your new chapter in life, and as mentioned earlier in the thread, I'd also like to see a "special badge" in your honor for the tireless work you have given the community! Don't be a stranger...

Hi all! I would like to take advantage of my CUDA on this Proth Prime Search (LLR) challenge, but I see it is still in beta testing. Will we be able to use it soon???
Thanks... Ron :)

Yes it does work! The w/u has processed, but I'm confused on the results message...
GFN testing completed

Has the w/u been tossed out?


The work unit had expired on the server before you returned the result.


O.K. that explains it!
On a positive note, another prime was found on the second terminal window, and the new version of pfgw 3.6.1 processed the prime without a hicup!! Good work Mark!

I've posted pfgw 3.6.1 here: https://sourceforge.net/projects/openpfgw/. This is a Mac only release to address the hanging issue. I suspect a faulty build of GMP. I had been using GMP 5.0.1 which I built with llvm-gcc. Apparently llvm-gcc (which comes with Xcode 3) does not build GMP correctly. I had to upgrade to build GMP (now at 5.0.2) and pfgw with clang (which comes with Xcode 4 IIUC).

Confirmed that it works. PRPClient package for MacIntel has been updated to pfgw v3.6.1.

Thanks Mark for taking the time to work this out! I guess I've stumbled onto a "bug" in the program for the Mac, but that's what we're here for ... right? Thanks again!

Ron

Now I found my second PPSElow-prime and I have the same problem again. I can not report the prime-number.

The terminal window is frozen and shows:
"2167*2^303758+1 is prime! Time : 137.950 sec."

test_results.log:
[2012-01-17 17:16:38 CET] Server: PPSElow, Candidate: 8613*2^303756+1 Program: llr Residue: AFB6B1D51B64D2D9 Time: 136 seconds
[2012-01-17 17:18:57 CET] Server: PPSElow, Candidate: 2167*2^303758+1 Program: llr Residue: PRIME Time: 138 seconds

The prpclient.log shows only the last non-prime:
[2012-01-17 17:14:16 CET] PPSElow: Getting work from server prpnet.mine.nu at port 12000
[2012-01-17 17:14:22 CET] PPSElow: PRPNet server is version 4.3.6
[2012-01-17 17:16:38 CET] PPSElow: 8613*2^303756+1 is not prime. Residue AFB6B1D51B64D2D9

Maybe it's a problem only with the macintel-version of the prpclient 5.0.4. I think that Ronald Littlefield has a Mac-computer too.

I hope, somebody can find out, what's causing the problem and fix it.


You are correct!

It is now doing something different! Looks like it's re-checking...?

2623*2^303036+1 is prime! Time : 140.398 sec.
GF_sprime_2: 2623*2^303036+1 127500/303035
GF_sprime_3: 2623*2^303036+1 25000/3030355
GF_sprime_5: 2623*2^303036+1 15000/3030355

I believe it is checking to see if the prime that you found divides a generalized fermat number.
Just let it run.


My terminal window is still open, but has not done anything since yesterday! It seems that it is frozen on the message: 2623*2^303036+1 is prime! Does it usually take this long to process the data? My test_results.log file shows that there was a prime found, but I don't know why my window is locked up...
Here is the copy of the message in my logfile: [2012-01-14 13:02:50 PST] Server: PPSElow, Candidate: 2623*2^303036+1 Program: llr Residue: PRIME Time: 92 seconds

Thoughts....

(edit) Oh, BTW, I initiated a ctrl-c to close the terminal window, but a proper shutdown has not happened yet. This is what is currently on my screen: "^C
Ctrl-C detected, shutting down the program."

OK! Yea, this is a new process to me!

Just let it be, don't close the window. It should continue on when it's done doing some other tests.
Edit: Oh yeah...congrats on your find.


;~) Thank you! This is my first prime found using the prpnet client that I'm aware of...
