Sorry, no contest, I'm disabling Short WUs. At least these GIANNIs are seriously wrong-rated as Short and their gain is seriously low. They need to be re-evaluated. Personally I find the whole short queue long queue issue with the huge credit differential irritating. I understand the rational, I buy part of it. Reeks of elitism though IMO. People want to help out here because they like the goals of the project. Sometimes the project makes it hard to do. |

I was interesting about gianni and from my results short giani (as example 23k secs) runs longer! then a long old nathan (as example 21k on the same card). But giani pays 31k credits while nathan paid 70k. So the argument it cant be run in long queue is not right. Or the old nathans are not right in the long queue ;) from the creditside it is right in the long queue. I wanted to mix one of the machines with short and long to get a better place on the next publication but i deactivaded short too at the moment ^^ DSKAG Austria Research Team: http://www.research.dskag.at

The previous Nathan's were put in the Long queue as there was no other work available, and most people are attached to the long queue. So it was just to accommodate crunchers that don't check the forums frequently. They were also made to a length to accommodate everyone. Also, some testing was being done around that time, and I think they might have been using the short queue for that on occasions, as well as the beta queue. Nate has already explained his reasons, and in this thread, http://www.gpugrid.net/forum_thread.php?id=3370&nowrap=true#30017 FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help |

I am interested in the goals of GPUG and the science behind it. If I wouldn't - and were only interested in the credits - I would be running DistrRTgen, which "pays" good and like clockwork. I'm also a long-time WCG cruncher. I guess credit and the associated rankings is the vanity-satisfying "fix" we get that keeps us going! :) |

Sorry but I think it would have weighed an average / high among the series GTX5xx GTX6xx and not everyone has the GTX680 or TITAN, GTX780 or soon. Well.. giving the expected run time for the fastest cards is very different from expecting everyone to have the fastest card. As cards get faster GPU-Grid has to adjust the WU durations in order not to overwhelm the server. You can argue that you want shorter WUs or a different time estimate (your average.. which would require more work to calculate), but don't blame them for sticking to their word. [I think the current Giannis are too long, too.. but that's not a fundamental issue and could easily be fixed, at least when the next WUs are submitted] MrS Scanning for our furry friends since Jan 2002 |

That's weird, the numbers and operators are missing between the greek letters in your formulas.. ;) MrS Scanning for our furry friends since Jan 2002 |

My concern is not the credit, but the deadline. PLEASE think for a while that all computers running GPUGRID don't have the fastest GPU. My home computer has a GT 540 M GPU, and GIANNI WUs last from 48 to 72 hours. If I have 2 projects sharing GPU resources at 100-100, it takes 4 to 6 days to complete. And the deadline remains desesperately set to ... 5 days, the same than shortest WUs. I16R3-GIANNI_VIL1-0-3-RND7631_3 has used 242,046.30 seconds (67 hours) of my GPU time and was out of time when completed (without error). BINGO ! You've got the result and I've got 0 credit. I1R8-GIANNI_VIL1-1-3-RND1955_1 has been loaded during the execution of the previous one. When starting, there were only 2 days remaining to complete, so I had to abort it. I've got 0 credit, but at least I have spared my GPU time. I've a very small chance to see the current WU (I16R89-GIANNI_VIL1-2-3-RND3587_1) complete in time because it will only last about 52 hours. Please increase the deadline for Gianni tasks. |

WAOUH. I16R89-GIANNI_VIL1-2-3-RND3587_1 passed OK whilst completed half an hour after the official deadline. I tailored my resource sharing between projects with "normal" WUs in order to get them in time. If you suddenly increase the workload by 2 or 3, you should increase the deadline by the same factor. But nobody here seems to take my remarks into account. It's a shame. So I repeat my demand : Please increase the deadline for Gianni tasks. |

Hello: A card that does not allow complete a task (short or long) in GPUGRID on a GPU 24H is not suitable for this project, as designed, it's that simple. Greetings. |

WAOUH. You seem to be using two laptops. While their GPUs may be powerful enough for general laptop use and gaming, even for some BOINC GPU projects, unfortunately they are not suitable for GPUGRID. I had a GT 440, close in specs with one of your laptop cards, and it only managed to complete work within the deadlines, forget bonuses! I upgraded to a GTX 650TI, which manages to crunch the longest WUs in just under 24h. A sad fact perhaps, but GPUGRID seems to be a demanding, high-maintenance project: not only does it need powerful GPUs, you also have to keep an eye on what WUs you get, how they progress, abort them quickly (so somebody else gets them quickly) if you spot something going wrong, etc. To be honest, I am enjoying this! At least for the time being. And of course, I didn't have a problem to upgrade my GPU to accommodate the project's crunching appetite! That may not be the case with everybody of course and that's perfectly fine! As long as you wish to contribute with number crunching, there are many projects out there that would appreciate your contribution! |

Usual GPUGRID "short tasks" last around 24 hours on my 2 fastest hometoys. I'm not competing for bonuses, so I tried to share their limited GPU resources between 3 BOINC projects at 100-100-100, and it worked. Maybe it's a sucker's idea to do so with my laptoys, but they're good enough for my needs: no games, no video, just little home office, mail access, surf on internet and a CUDA GPU board for BOINC. One of them has a very comfortable backlighted keyboard, and this is quite more important than to have the fastest GPU board. You know what? I'm happy. I'm an old timer. I still have a 12-years old Core 2 Duo crunching Enigma 24/7. My concern is that Gianni WUs are not short tasks: they last 2 times more than usual ones but they have the same deadline. To solve this issue, I'll try to dedicate one of my ridiculous laptoys at 100% to GPUGRID. |

While I agree that those Giannis are too long for the short queue, you should be aware of how GPU-Grid works: WUs are generated based on the results of returning WUs. They can launch parameter sweeps etc. in parallel, but at some point they need entire strings of WUs finished to evaluate the results and decide what's next run. Simply extending the deadline would make the results take longer to be returned and hence slow the project down. Even if overall throughput was increased because more slower GPUs would participate.
