| Summary | 0003902: threadpool with mingw-w64 | ||||
| Description | This report is for us to get threadpool running on windows. engine-legacy in threadpool now builds for me on arch with the following mingw-w64 packages installed: https://aur.archlinux.org/packages/mingw-w64-binutils/ https://aur.archlinux.org/packages/mingw-w64-crt-svn/ https://aur.archlinux.org/packages/mingw-w64-gcc/ (with --enable-threads=posix) https://aur.archlinux.org/packages/mingw-w64-headers-svn/ https://aur.archlinux.org/packages/mingw-w64-winpthreads/ I am not sure the -svn packages are needed, perhaps the vanilla packages are fine. To get std::thread working use --enable-threads=posix instead of win32 when building gcc. I needed some spring source changes, see attached patch_cr1. I had to place the following dlls next to spring.exe to have spring.exe not complain about missing DLLs in my win7 qemu vm: libgcc_s_sjlj-1.dll libwinpthread-1.dll libstdc++-6.dll Spring didn't start fully, my win7 was missing proper opengl driver so extensions were missing. I built a small test app which used std::thread that at least worked when running on win7. | ||||

from the mingw64 homepage: "winpthreads, a implementation of POSIX threads for win32 is also available under the experimental directory. Its main goal is to support C++11 standard threading, which supports only using POSIX threads at the moment. " http://mingw-w64.sourceforge.net/ |

USE="openmp cxx -fortran" EXTRA_ECONF="--enable-threads=posix" emerge -va =cross-i686-w64-mingw32/gcc-4.7.3 doesn't compile: http://paste.springfiles.com/view/09da085e |

i'll try to setup mxe: http://mxe.cc/ |

FYI: jk tried with boosts threadpool implementation which seems to work. spring.restart worked as well! can't say anything about drawbacks, etc... |

jk seem to have solved the last problems. windows users can test now: http://springrts.com/dl/buildbot/default/threadpool/ |

Ok did some playing around with it. The good news is that it makes use of all 6 cores on my AMD FX-6100 (hooray!). Most usage appears to be occurring in cores 5 and 6, occasional bursts in core 2, minimal usage of all other cores. Loading times are MUCH faster. No gains in performance though, in fact average framerate is lower then 94.1.1-730-g1852c22 with identical settings. Still, all 94.1+ git builds run much jerkier and slower then 91.0 even with near same framerates, threadpool doesn't improve this. Some /give all tests on Folsom Dam Deluxe and BA 7.78: -Threadpool, with /luaui enabled, after /give all ~25fps -with /luaui disable increases to ~38fps -94.1.1-730, /luaui enabled, ~30fps -/luaui disable ~45fps EDIT: I swapped around the first numbers, sorry! |
