Reliability of computer brands
(Message 29664)
Posted 46 days ago by  robertmiles 
I'm thinking of buying another computer. One possibility is an HP with one GTX 680; another is a Cyberpower with two GTX 680s. Do any of you have enough experience with at least one of these brands to comment on their reliability, when subjected to heavy BOINC usage? |

Disabling CPU, using GPUGRID only for GPU, possible?
(Message 27559)
Posted 197 days ago by robertmiles
BOINC makes it difficult to download enough CPU workunits if you have a GPU but no GPU workunits - it insists on getting a GPU workunit before it will even try to get CPU workunits, even if you've told it not to run anything on the GPU. Rosetta@Home tried recompiling their application to run on a GPU, and found that it is so serial in nature that it often runs slower on a GPU than on a CPU. Therefore, they gave up on offering any GPU workunits any time soon. One way to get close to running on the GPU only is to subscribe only to BOINC projects that offer only GPU workunits. |

An idea for mid-range GPUs
(Message 27558)
Posted 197 days ago by robertmiles
An idea to consider for mid-range GPUs, without creating more types of workunits: Add a new selection for workunit type, meaning that the short workunits are preferred, but send long workunits if short workunits are not available. |

GPUGRID and WCG HCC
(Message 27069)
Posted 248 days ago by robertmiles
The new GPU workunits for the HCC project at WCG do not seem to cooperate well with GPUGRID workunits. For computers running both, the GPUGRID workunits have long delays at the last checkpoint (the one within 5 minutes of finishing), and therefore will not finish as quickly as they used to for the same computers. If the work after that checkpoint is CPU-only, could you investigate whether it is useful and possible to give up use of the GPU just before that checkpoint? Also, could you contact the HCC project at WCG to see if the two projects can cooperate better at allowing long workunits to finish? |

PAOLA_3EKO_8LIGANDS very low GPU load
(Message 26783)
Posted 288 days ago by robertmiles
3EKO_19_4-PAOLA_3EKO_8LIGANDS-3-100-RND3778 has run 123 hours so far, 57 to go, 67.623% progress already past deadline http://www.gpugrid.net/result.php?resultid=5800806 Is this a reasonable run time on a GTX 560? Or is it so much past what is expected that I should abort the workunit? |

Why not list the GTX 6nn data available currently, but clearly mark it preliminary? That should at least be better than no data at all. |

New CUDA4.2 applications are out for Kepler GPUs
(Message 26053)
Posted 354 days ago by robertmiles
i got a unit on a gtx260 (win7 x64 latest boinc and drivers), but i had to abort it as it was making my computer completely unusable with 99% usage. 99% usage of what? If it's a CPU core, try telling BOINC to leave one CPU core free for programs other than BOINC workunits. If it's the GPU, I haven't found a usable method yet. |

Substantially faster for what GPUs? Only those with the Kepler chips, or the older ones with Fermi chips also? |

Select project by GPU
(Message 25796)
Posted 364 days ago by robertmiles
I'd expect that to require changes to BOINC, not just to GPUGRID. Some other people with more that one GPU per computer might want that too, though. Another idea: If the motherboard has a separate GPU for use when there is no graphics board, how hard would it be to make BOINC use that GPU also (probably not for GPUGRID)? |
