Post: Hello, Would it be possible to prevent "Ghost Crunchers / computers" to upload a full cache of WU's (sometimes > 1000) without calculating them. The server already cancelled some of these uncalculated WU's, will cancel the remaining WU's automaticaly, but these crunchers will again and again receive a brand new batch of WU's that they won't return in time. As I was wondering why I have so many "waiting validation" (> 500), I found at least 3 or 4 computers having > 1000 WU's + 0 returned WU since April 11th and already several series of "cancelled by the server" WU's. Thank You Best Regards |

Post: Hello, could someone explain to me why there are so many changes in the WU's lenght ? Below instances = AVX, (all on the same machine - ID 54940 !) but same happens with SSE2 and SSE3 : ALL WU's need > 2x more time to complete than 4 or 5 days ago ... ? Thank You

Post: Hi Mikey, Thank you for your message. Sorry, but ... a) even if a dedicate a cpu core / GPU WU, (app_config) it slows down and sometimes freezes the CPU WU's ??? b) CPU time shown in the stats don't confirm what you are writting. Less than 10 seconds CPU time per GPU WU (CUDA55) c) ie on GPUGRID, I know how to "oblige" BM to use the core CPU it is supposed to use, and there is a real gain. (CPU time = GPU time) d) don't understand why, but when running Asteroids on CPU + GPU, my machines are crashing e) What's the point wasting GPU time when the gain is only 50 % ag AVX WU's ? If optimzed, these CUDA app should/could run in about 10 minutes ... Nevertherless, I like the project, and I try to understand how to improve crunching on it :) Best Phil1966 |

Post: ASTEROIDS GPU is not only slowing the CPU very seriously, but today I tried to run it on CPU + GPU. All CPU WU's are in "waiting mode". Waiting for what, I don't know. As far as I know, it's the only GPU project having such a negative impact on the CPU while it is not supposed to. Even if you dedicate a CPU core to ASTEROIDS GPU. It looks like no improvement was made on these GPU apps since launch, regardless the numerous crunchers remarks. It's "sad". Best, Ph. |

Post: Not sure why you want an app_info but then I'm app_info challenged. You're 100 % right, except that I don't think Asteroids uses DP. (see this post : http://asteroidsathome.net/boinc/forum_thread.php?id=268) Like your point of vue about Windows :D Ran some tests yesterday, and AVX "better" than GPU. http://asteroidsathome.net/boinc/forum_thread.php?id=268 |

Post: Hello ! As discussed here : http://asteroidsathome.net/boinc/forum_thread.php?id=200&postid=2758#2758 I made some tests today, and here are the results + questions. CPU tests Crunchbox = ASUS Z87 Pro / i7 4770K @ 3.9 Ghz / AIO WC Nepton 140XL / etc i7 4770K @ 3.9 Ghz - HT OFF - 3 AVX WU's at the same time = Aver. 3677 secs / WU = 11040 PPD / CORE i7 4770K @ 3.9 Ghz - HT ON*** - 7 AVX WU's at the same time : Aver. 5460 secs / WU = 7680 PPD / CORE i7 4470K @ 3.9 Ghz - HT ON - 7 SSE3 WU's at the same time = Aver. 8100 secs / WU = 5120 PPD / CORE *** A powerfull Aircooling or Watercooling is MANDATORY to run AVX WU's with HT ON ! => One can see the benefits of each type of WU's Thank you for the various applications you offer. It would be nice to have an option in the account preferences rather to be obliged to use an app_info.xml file. (Not user friendly for beginners) GPU tests GTX660Ti CUDA 55 : 3767 secs / WU = 11040 PPD = same as 1 CORE CPU AVX HT OFF GTX770 : 3450 secs / WU = 12000 PPD = little better than 1 CORE CPU AVX HT OFF => How comes the GPU tasks are so slow, given the fact that : All WU's = 1200020 GFLOPS A much more significant improvement was observed on other projects that propose to crunch on GPU or CPU the same type of WU's ie : PPS Sieve & GFN Short : GPU WU's > 15 times faster than CPU. As I am not a specialist, and with all due respect, I just want to understand why the same kind of speed cannot be reached with Asteroids. Finally, once running a GPU task, the crunchbox slows down + ALL (CPU+GPU) WU's disappear when closing BM. Thank You Kind Regards, Phil1966 |

Post: Meanwhile we have increased wu's lenght. Now it's about 3500s. Understood ! Thank You for your quick answer ;) Kind regards Philippe NB I am still planning to run a test on my crunchbox as soon as the project becomes available :D |

Post: My new AMD A10-7850K with Steamroller cores seems to be so far a little faster with the AVX version. Unfortunately, he gets currently only SSE2 WUs. Hello ! If you run XP/W7/W8 you need an app_info.xml in order to receive AVX WU's. ie (this is the one I found on the forums and use with W7 / i7 4770K / HT OFF) Philippe <app_info> <app> <name>period_search</name> <user_friendly_name>Asteroids</user_friendly_name> </app> <!-- AVX --> <file_info> <name>period_search_10210_windows_x86_64__avx.exe</name> <executable/> </file_info> <app_version> <app_name>period_search</app_name> <version_num>1021</version_num> <avg_ncpus>1.00</avg_ncpus> <max_ncpus>1.00</max_ncpus> <plan_class>avx</plan_class> <file_ref> <file_name>period_search_10210_windows_x86_64__avx.exe</file_name> <main_program/> </file_ref> </app_version> </app_info> |

Post: Haswell can crunch one task in abou 720s with avx version. Hello ! Do you mean : Faster than the GPU APP ???? Intended to do some tests on AVX this week-end, but as the project is down for maintenance, I took some time to read the forums, and I found the above post ... Will post the results here, but I cannot believe that 1 task can be crunched in 720s, faster than a CUDA task crunched by a GTX TITAN. Hereafter the details of the crunchbox : MB = Asus Z87 Pro CPU = i7 4770K @ max 4.4 - HT OFF ! WC = Nepton 140XL GPU = GTX770 Gigabyte 4 Go RAM = 2 x 8g Corsair Vengeance 1600 etc W7U (Unfortunately, have not installed Ubuntu on this crunchbox, yet) Kind Regards, Philippe |

Post:
Then I don't understand why you launched this GPU app ? Is it a test for a futur "different / new type of" WU's ? Have tryed AVX WU's on an i7-4770K ... but I don't know why, very very slow + only increasing the CPU temp. I guess one should run AVX on 4 cores only => no real gain <-> SSE3 on 8 cores ... Wish you a Happy New Year ! |

Post: My friends, please beware AVX code on Hotwell = increased VID = more heat. Hello Thank you for the link. In order to receive only AVX, what should I do ? Put the SSE2 and SSE3 at 0 ? Thank You Kind Regards Philippe |
