Without using an opti app Cpu performance and credits are poor. Is there any plans to put out better cpu apps? I know that the stock app is pretty much unusable on a CPU. FWIW, it seems that i can reduce crunching times to less than ~5h on a XEON(5365@3 Ghz, core 2 based)... Anyway, i do know that that's far away from what the previous opt app did... I'd be interested to know some crunch times on different CPUs with the stock app (cpu:time:credits), before using a LUT for the INT EXP part... (wich i know for a fact that the previous optimized CPU app used and i allready suggested to Matt for the GPU BUT it'll greatly speed up the stock CPU app as well) ____________ Join BOINC United now! | |

On a Quad XEON I had a RAC of about 4800 to 5000 credit/day with the old 0.21SSE3 optimized app. Now with the standard 0.50SSE2 it went down to about 800 credit/day. | |

If people are looking for credit then there is no point hanging around here any more, that is quite clear. Those of us interested in the science will be the only ones to stay. A shame because it was a good payer for quite a while, but I guess that nothing good lasts forever. | |

From looking at it for either credit, science or both it doesn't seem as worth it now. When the same task is much longer for the same science & credit it doesn't make sense to me. | |

I still think that the science is worth it, even if it now does take longer than it did, for less credit. I will be sticking around, but I can't pretend that I'm not disappointed. | |

The next CPU release will be faster for most people | |

So you're really not interested in the science? JK, hopefully the credit levels will return. I know the whole credit issue mystifies the MW team, but they have to realize that DC BOINC has become a game/hobby/competition for many. No different than any other completion of which us humans are so fond. The added bonus is that we get to help science. | |

So you're really not interested in the science? Yes I am, which is why I said I would be sticking around :-) JK, hopefully the credit levels will return. It would be nice to think so. I know the whole credit issue mystifies the MW team, but they have to realize that DC BOINC has become a game/hobby/competition for many. No different than any other competition of which us humans are so fond. The added bonus is that we get to help science. Happy to agree, but don't hold your breath ... ____________ Don't drink water, that's the stuff that rusts pipes | |

I don't do it for credit, I run Seti for 11 years now and since boinc exists I run seti/einstein/lhc/milkyway only. It's just dissapointing that milkyway credits went down like this, but I still run it. | |

The next CPU release will be faster for most people Yes, quite a bit faster than the 0.50sse2 app. My Xeon needs ~ 8800 sec. for a 213 credit WU (13_3s_fix20)(Intel compiler). Depending on the compiler used for the stock app, it should be ~ 10k sec(or less). Not bad for the first try. ____________ Join BOINC United now! | |

yup, thanks Crunch3r! and if you need a beta tester for your optimized CPU app... ;-) | |

Without using an opti app Cpu performance and credits are poor. Is there any plans to put out better cpu apps? Is this from using compilation flags, or changing the code? If any of the changes are things we can do on our end, we'd be more than happy to implement them. ____________ | |

That will be great to get a decent CPU app, not run a single MW WU since my PC upgrades to GTX460's coincided with the project upgrade and the Nvidia opti apps disappeared. | |

does this thread strictly pertain to an optimized app for de_separation tasks, or does it include n-body tasks as well? I don't do it for credit, I run Seti for 11 years now and since boinc exists I run seti/einstein/lhc/milkyway only. cool, i strictly participate in those 4 projects as well...though i'll probably join Muon1 DPAD (a non-BIONC project) when i get around to reallocating my resources. ____________ | |

i'll probably join Muon1 DPAD (a non-BIONC project) when i get around to reallocating my resources. You can also do Muon1 through Yoyo if you like. | |

Would it be possible to also issue a stock app_info.xml for MW@Home? It might eliminate some problems, especially for those of us who are not programmers, as well as helping with any troubleshooting by getting everyone on the same sheet of music.Not sure what you mean by stock app_info. The point is it kind of isn't. Do you mean a template or something? | |

You can also do Muon1 through Yoyo if you like. thanks for the suggestion. unfortunately i can't run Muon1 through Yoyo@Home without competing against my team (TeAm AnandTech). so i'll have to run the standalone version when i eventually get into it. ____________ | |

The point is it kind of isn't. Do you mean a template or something? Hi Matt, what all GPU-Crunchers want to have is a app_info.xml. Nobody wants to crunch de_separations on CPU if a GPU is available, but disable the CPU disables also the nbodys. So you need some way to make that decision. Using different settings for home/scool/work will not help in every possible situation; other guys want to crunch two wu's at the same time (during calculation of the likelyhood the GPU is in IDLE), so the best solution is using an app_info. But it's not easy to compile a good working app_info. You need al lot of numbers, there are a lot of possible arguments also. This is why peaple want a app_info, which gives them the ability to decide, which type they want to crunch. There is another easy way to solve most people's problem. Add a checkbox to the personal settings 'Run CPU-Apps if GPU-Apps are available?' This enables the crunchers to set 'Use CPU' to on, getting nbody CPU and de_separations GPU wu's only. And there is no need to update the app_info if the version changes. Alexander | |

At any given point in time, MW has a number of computational campaigns underway,each with its own app. Some benefit from the GPUs, some don't. | |
