2019-02-05 09:14:47 condorella/rx-480 Bye[/CODE]Timing for 1280K fft at 2.95ms/iter was anomalously higher than for 1536k (1.33 ms/iter)
Similarly for 2304K at 5.15 ms/iter vs. 3072K at 2.75 ms/iter
I only tried the fft lengths the program chose for known Mp exponents. So there may be more cases of low speed by default selection.
There were cases where the same fft length was a few percent faster or slower in V6.1 than the best previously observed in V3.5 to v5.0.
The executable in the attached zip file is considerably smaller than the one for V6.0, because I omitted doing "strip openowl" at V6.0.

Something is wrong with gpuowl !!!
 
[QUOTE=kriesel;507780]V6.2 openowl build for Win64 and first takes

No executable posted yet. Skip to the end for why.

Same 3 warnings again during the build process as listed for v6.1.

-h worked with or without a valid worktodo file, good.

openowl -h output:[CODE]2019-02-05 17:39:12 gpuowl 6.2-4a213af

Command line options:

-user <name> : specify the user name.
-cpu <name> : specify the hardware name.
-time : display kernel profiling information.
-fft <size> : specify FFT size, such as: 5000K, 4M, +2, -1.
-block <value> : PRP GEC block size. Default 400. Smaller block is slower but detects errors sooner.
-carry long|short : force carry type. Short carry may be faster, but requires high bits/word.
-D <value> : P-1 second-stage D block size; multiple of 210; default auto based on GPU available memory.
-device <N> : select a specific device:

Same with prime 86243...

Thanks -- I've been careless, the same bug strikes again!
Anybody can check if he found a misreported prime by searching for fffffffffffffffc in gpuowl.log, e.g. with grep under linux.
The fix is underway.

Fixed now, please re-checkout.

It's fine to upgrade in the middle of an ongoing PRP test, the result will be good.

The problem is that some exponents have already been computed to completion. I would double or triple check them...

No need. If the final residue was not 0xfffffffffffffffc (i.e. -3), there is no risk of being prime. Just do this:

grep fffffffffffffffc gpuowl.log

and only re-check the exponents that produced that as final residue (most probably there are none).

I strongly recommend running some known-mersenne-prime low exponents before committing to github for the author, or before using for production for the end users.

[url]https://www.mersenneforum.org/showpost.php?p=506082&postcount=3[/url]
(And look closely at the results, more closely than I did for v6.1 the first time yesterday!)

And only from the last saved interim iteration count before the previous completion, not the whole computation duration, and which the program will do automatically. (Unless you deleted the interim files yourself: p.owl and p-prev.owl) The interim residues checked out ok, as did the final, in the cases I checked. It's only the very last bit that went wrong.
