Posted 17 Mar 2017 by koschi Post: Btw, not exactly AVX related, but since we have everyone on board already. The news on http://www.numberworld.org/y-cruncher/ says Ryzen can run FMA4, even though the FMA4 feature flag is not set. I tried to run www.boincunited.org/opt_apps/period_search_10210_x86_64-pc-linux-gnu__fma4.tar.bz2, but it failed within few seconds, SIGILL: illegal instruction. Any other way to confirm this? I've seen you using GCC earlier somewhere, can you give 6.3 a try, maybe with -march=znver1 and -O3? Have you tried to build with Clang? As per the Phoronix results, it can make a substantial difference in some apps. http://www.phoronix.com/scan.php?page=article&item=gcc-clang-ryzen |

Posted 14 Mar 2017 by koschi Post: Thanks! That one is working, WUs are running 2 minutes already, results in 2-3 hours... Where is the difference, which flags did you use / skip in this one? |

Posted 13 Mar 2017 by koschi Post: Thanks for the compile, unfortunately it seems not to work yet :-( http://asteroidsathome.net/boinc/result.php?resultid=148531759 btw, the link works fine with wget or Chromium, no need for MS to be involved ;-) |
