Posted 10 Mar 2017 by Crunch3r Post: So, if the problem is lack of disk space, how much money does it take to double the disk capacity? This is not a sarcastic question. I'm serious. Is this just a hardware problem or are there software issues as well? Would you please consider creating a 'Campaign' over at http://www.bitcoinutopia.net/bitcoinutopia/index.php to get some Bitcoins to fund some new hardware ? |

Posted 9 Mar 2017 by Crunch3r Post: Hi, this ones for linux 64 bit. http://www.boincunited.org/opt_apps/period_search_10210_x86_64-pc-linux-gnu__avx128.tar.bz2 if that one works, i'll compile one for windows too. |

Posted 27 May 2016 by Crunch3r Post: wow, this looks very good.. incredible performance, perfect consumption and good pricing.. Those rating are single precision (FP32) and are useless here, since Asteroids uses double precision(FP64)... AFAIK, a gtx 1080s FP64 performance is 1/32 FP32 peak flops... A GTX 660TIs FP64 performance is 1/24 FP32... |

Posted 18 Jan 2015 by Crunch3r Post: well, the easiest way to deal with it, is downloading that app -> http://www.boincunited.org/period_search_10210_windows_x86_64_bd_fma4_gcc.zip using an app_info.xml. No doubt about it, it's the fastest app you can run on your cpu. since it's using fma4. |

Posted 16 May 2014 by Crunch3r Post: OK, to anyone who want's to try the BD fma4 app here is the link. http://www.boincunited.org/period_search_10210_windows_x86_64_bd_fma4_gcc.zip It's using anonymous platform and the only thing to do is to copy it to the project directory. I won't go into specifics on how to install the app, since only experienced boinc users should have a go at it. |

Posted 21 Mar 2014 by Crunch3r Post: Is there any speedup over avx? AVX was always slower than the sse2 or sse3 app. Not even using the intel compiler could fix that. So i've switched to gcc 4.8.2 and recoded the parts of the app that could make use of amds fma4. The real question is, if the app is faster than the sse2 one (fastest of them all), however , as i've mentioned earlier, my cooling sucks and my fx 6100 keeps trottling so there's no way of me telling what the differece is. |

Posted 18 Mar 2014 by Crunch3r Post: Is someone interested in experimenting with a app that uses the AMD fma4 instruction set ? I rewrote the code. |

Posted 17 Mar 2014 by Crunch3r Post:
I wish i could throw in some numbers but unfortuantely, my cooling is not efficient enought.. (meaning my fx6100 keeps throttling down to 1.4 GHz)... So it's a guessing game. So, the only available option is testing it on some bullozers that can handle the heat ;) |

Posted 17 Mar 2014 by Crunch3r Post: Is someone interested in experimenting with a app that uses the AMD fma4 instruction set ? FWIW, i've been running it for a couple of weeks now at it works (valid results). If someone is interested i could upload it. Let me know. |

Posted 15 Mar 2014 by Crunch3r Post: And we don't yet know if the person/persons involved have 24/7 connectivity. http://www.planetaryresources.com/ I'm pretty sure they are online 24/7...
You're kidding me ?!? Of course those machines are servers !
I'm guessing it's in their best interest to run asteroids@home given the link i posted above... Guess what that company is interested in ...
Bla bla bla... just limit the "in progress WUs" per core to let's say 15... that'll solve the "problem" for those that can't wait... Instant credit would't that be cool ?!?... Not going to happen here... So why don't you all chill till you get your credit... ?!? |

Posted 18 Feb 2014 by Crunch3r Post: My answer from PM, just corrected some typos: The problem is the OSX avx app (Intel 64-bit Mac OS 10.5 or later 102.10(avx_osx) ) ,which was compiled using llvm. I've send you a PM couple of weeks ago,that it needs to be removed! Somehow that didn't happen. I do have a new OSX avx app here that validated on my xeon 1240, however it's way slower than the sseX OSX app, so no need for a avx app on osx unless you wanna waste time! |

Posted 18 Nov 2013 by Crunch3r Post: Thanks for pointing on 780ti dp speed. I thought it's like titan and it is not. Ok. So let's be honest... If we're porting asteroids to gpu, the only way to go is opencl! That will of course take into account that all nvidia gpus except the titan suck at DP... So no need to waste energy in porting the app to cuda when we already know that asteroids will be dominated by ATI/AMD gpus because those are less crippled regarding DP performance. To face the fact, Asteroids will be a "second" Milkyway@home regarding GPU dominance. AMD/ATI GPUs will dominate and nvidia will be left biting the dust. |

Posted 7 Nov 2013 by Crunch3r Post: I have released the optimized versions for OS X, which were compiled by Crunch3r. I've compiled new apps 32 and 64 bit. There seems to have been an issue with the sse2 app getting invalid results. I'm got a hunch that it's due to using clang instead of g++. anyway, i've uploaded the new apps(see below). http://www.boincunited.org/opt_apps/asteroidsathome_osx_10211_32bit.tar.bz2 http://www.boincunited.org/opt_apps/asteroidsathome_osx_10211_64bit.tar.bz2 (no need for sse2) The avx app might follow later since i have to figure out why it's so slow compared to the sse3 app. |

Posted 26 Oct 2013 by Crunch3r Post: OK.. i've compiled sse2, sse3 and avx apps. For the moment OSX 10.5 &64 bit only. the 32bit app is uploaded as well. It's 'only' sse3 since avx is way slower. |

Posted 25 Oct 2013 by Crunch3r Post: Great, thanks. Yes, both. And what about SSE2? I have no view of current CPUs on Mac. No need for SSE2 since all macs have at least sse3 available. |

Posted 25 Oct 2013 by Crunch3r Post: I'll compile a new binary for OSX. It'll be available for download tomorrow. Do we need both sse3 and avx ? |
