Don't know what the situation is regarding a new app but if an OpenMM app was compiled using VS 2010, in theory it might still work on XP. The latest VS version doesn't support XP IIRC. Other factors (CUDA Drivers, a mainstream Volta release) might still prevent it working and if the WDDM overhead isn't an issue with OpenMM then supporting XP might be unnecessary. |

Assuming an OpenMM based Acemd3 app turns up, all & any user side tweaks, modifications & optimizations will need to be reassessed, primarily to see if they work. Coolbits, nice, SWAN_SYNC, process lasso, priority, HT ON/OFF, freeing up a CPU/thread... Which GPU models will work best/are the best value would need to be reassessed. Some may no longer work, some might be better... The importance of PCIE & CPU rates/strengths/weaknesses might change as might the operating systems we can use... |

Select no new work from the project. Allow existing work to complete, then update+restart before accepting work from the project again. |

Mixing GTX 10X0 GPUs with older GPUs in the same system
(Message 47033)
Posted 2555 days ago by skgiven
The new app allows for mixing of new and older generations of GPU's. For example a GTX970 can now be used alongside a GTX1060 is a Windows 10 system. The thread called DO NOT MIX GTX 10X0 GPU with older GPUs in the same system has been retired. Will move the last few posts to here... |

It sure would be nice if they purged all the outdated error tasks from 2014-2016.

Power outage destroyed results

Can I move the BOINC directory to another drive? It's currently in my C drive and I don't want decreased performance. Yes. I use smallish SSD's for most of my systems but on my W10 system the Boinc Projects (app/project data) folder is on a HDD. Basically, cut and paste the Boinc directory to the second drive (maybe backing it up along the way) and reinstall Boinc, pointing to the new directory -> the secondary drive. The executable will still be on the primary drive but all the reading and writing will be done to the secondary drive. Obviously disable the caching on the secondary drive! |

1 Work Unit Per GPU
(Message 46381)
Posted 2635 days ago by skgiven
At present there are not enough tasks to go around & most/all WU's have high GPU utilization so the project doesn't benefit (overall) from even high end GPU's running 2tasks at a time. Considering the recent upload/server availability issues it makes even less sense to run more than 1task/GPU. I would even go so far as to suggest its time we were running 1 task across multiple GPU's (for those who have them) - something that would also benefit those with 2 or more smaller GPU's; assuming an NV-link/SLi isn't required. By the way, GPU utilization isn't the end all be all of GPU usage; apps that perform more complex simulations, that require more GDDR, and more PCIE bandwidth are just using the GPU differently; not more or less (one probably comes at the expense of the other). When available tasks are exclusively low GPU-utilizing tasks, only then could the project benefit from high-end GPU's running 2tasks simultaneously. PS. The Pascal app (cuda80) is different from the previous app (cuda65) which can run mixed GPU setups; the latest app is exclusively for Pascal's (GTX 1000 series). |

It's not a useful e-currency ATM & until you convert it into one (bitcoins) it's of theoretical value only. Also, it's value against the bitcoin is steadily falling, & there are very few conversions; not many people want to buy Gridcoins. |

WU: BNBS
(Message 46379)
Posted 2635 days ago by skgiven
Well, even my PCIe2x16 conncected gtx1080 runs at pretty 95% per GPU-Z... which is a very pleasing figure. The BNBS accommodate the fast Pascal I presume and reduces the WDDM influence. Anyway, I am happy with the throughput. For comparison, I'm seeing 40% PCIe usage on my GTX1060-3GB running a PABLO_adaptive task (with the GDDR@8GHz & GPU at ~1950MHz on Linux; ~95% GPU Utilization. PCIe2 x16, while only running 1 CPU task on a tri-core AMD). Well it takes him 11 days to complete a BNBS2, now it should take slightly over 24 hours, so over 10 times as fast. I like to exaggerate as well :) If it takes over 5days there really isn't much point 'contributing'. I'm sure it must be especially frustrating to you when completed tasks are queued up on volunteers' computers because the server isn't in a position to accept the uploads and/or reports, and then again because the BOINC clients have gone into an extended backoff because of the connection failures. The continuation of this problem calls into question the credit/bonus system, unless of course you don't value it much/at all. When crunchers complete work quickly but can't upload & report they miss the bonus because the server isn't available, & BM backs off the retries. It's not the fault of the cruncher, doesn't help the project get through work, or retain crunchers! GPUGrid Stats regarding the fastest GPU's/systems/contributors become fickle, further frustrating some crunchers. But don't worry, there's only 2.5min to go! |
