[QUOTE=drh;260940]Thanks, will do this evening.

Well, it partially worked. The 4 exponents in question only had 1 of four mfaktc TF's accepted. Maybe it was because I had manually changed the bit assignments from 69-70 to 69-73 and ran them individually?

The exponents have been released, and without an assignment code, they will not be accepted, unless there is a way around that ... down to 42 lost GHZ-days.

How about trying to reserve the same ones again by limiting the trial factoring range to what you are looking for?

[QUOTE=TheJudger;260709]Hello,

here is mfaktc 0.17! :smile:[LIST][*]Users with "fast CPU + slow GPU" can try to enable AllowSleep in mfaktc.ini. This allows the CPU to sleep instead of running a busyloop if the CPU has to wait for the GPU[*]replaced compiletime option "THREADS_PER_GRID_MAX" with the runtime option "GridSize" (mfaktc.ini)[LIST][*]maximum "threads per grid" is now 2[SUP]20[/SUP] (was 2[SUP]21[/SUP]), default value is the same as before[*]maximum SievePrimes increased from 100.000 to 200.000[*]lower GridSize might increase the usability of your GUI while running mfaktc at the cost of slightly lower performance[/LIST] [*]no change in performance compared to 0.16p1[/LIST][/QUOTE]

Thanks Oliver,

works like a charm! The increased SievePrimes adds about 5% performance for me as ~5% less FCs are to be evaluated. And CPU load is now just 30-50% of one core. I like it!

PS: I now have some rudimentary OpenCL version using some of your code running on my ATI-GPU. It already found a few factors (proof of concept OK) but I just can't get it to utilize the GPU above ~10% ... work in progress.

Tried that as well, but PrimeNet responded saying that those exponents were not available ... probably since I had taken them up to 73 bits, 2 more than PrimeNet was expecting.

Oh well, lesson learned.

In discussion wih Prime95, GW told me that although mfaktc splits results to single bit levels, the server will take a result with multiple bit levels. I haven't encountered the need to do that, but I've also been reporting mfaktc results on relatively fresh logins.

Tonight while I was uploading some more results, I got a timeout. Eventually, almost everything got uploaded correctly, except this one exponent ...

no factor for M76120789 from 2^69 to 2^70 [mfaktc 0.16p1-Win barrett79_mul32]

found 1 factor(s) for M76120789 from 2^72 to 2^73 [mfaktc 0.16p1-Win barrett79_mul32]

I got credit for everything except the factor ...
Guess I can reserve it again and run the bit level again?

Update: can't reserve that exponent ... no assignment available.

Thanks,
Doug

False positive maybe?

You didn't get credit as it's a false result?

You can try to submit those 2 lines again manually. I have a 'free spot' on my GPU in 20mins, I'll run the test and see what result I get. I'll post result here. I won't attempt to get credit.

[/FONT]5666251615825315865351 = 2×5^2×7×11×13×83×17918861×76120789+1.
That was easy.

You will get credit for the manual submission of any [I]new [/I]factors even if the exponent in question is not assigned to you.

You will also receive no-factor credit if the exponent is assigned to you for something [I]other than TF[/I].

Okay I got same answer

Have you tried to just resubmit the result -- just the factor line? It is a legitimate result. No need to redo the range.

Just try again to submit the factor. If you ran into a timeout during upload of results than the primenet server typically missed some of your results.

Luigis (ET_) defactor (using libgmp) with slightly modifications agrees the factor. :smile:
[CODE]o@Lysithea:~> ./defactor.exe 76120789 5666251615825315865351

The factor 5666251615825315865351 divides 2^76120789 -1! K = 37218818211575
The factor 5666251615825315865351 is probably prime
