LLR Version 3.8.19 released
Hi All,
I uploaded today the version 3.8.19 of the LLR program. You can find it now on my personal site : http://jpenne.free.fr/ The 32bit Windows and Linux compressed binaries are available as usual. The Linux 64bit binaries are also released here. I uploaded also the complete source in a compressed file ; it may be used to build the MacIntel executable and also the 64bit Windows binary. The main new feature in this version is that MULTITHREADING is now available by setting oThreadsPerTest=<number> or t<number> in the command line. Thanks to Serge Batalov who showed me how simple it was to implement this! This LLR version is linked with the Version 28.12 of George Woltman's gwnum library. George has fixed in this gwnum version, the bug which sometimes affected prime or PRP tests done using multithreading and FMA3. When doing PRP tests, the Fermat test is now not strong by default, because it is time consuming... Now, if the input file name (PgenInputFile parameter) has changed while working with the same .ini file, the PgenLine parameter is forced to one. I made this update to fix the "CLLR bug" found by LaurV. As usual, I need help to build the 32bit Mac Intel binary, and also the 64bit Mac Intel and Windows ones. Please, inform me if you encountered any problem while using this new version. Best Regards, Jean Last fiddled with by Jean Penné on 20170220 at 11:34

With LLR 3.8.19 2 of the 3 numbers that failed in 3.8.18 now give the correct residue with 1,2,3,4,5,6,7 and 8 threads. These were the 2 that used 512K FMA FFT:
64598*5^23186941 33333*7^19170001 But the last one I found at 384K FMA FFT still fails for 5 and 7 threads (on an 8core 5960X), but works for 1,2,3,4,6,8. Code:

Hi,
Many thanks to George! He fixed in gwnum 28.13, the FMA3 problem remaining while running a PRP test with 5 or 7 threads. So, I updated on LLR 3.8.19 the source, and the Win32 and Linux binaries. I need help to update the Win64 and Mac Intel binaries with the same version of gwnum. Regards, Jean

So, I shall build a 3.8.20 LLR Version... When the upload will be complete for the source and all the binaries, I will then make the two previous "multithreaded " versions unavailable, because they are buggy. Regards, Jean
