JACT (Jet Another Cuda Thread): GPU undeperforms when all CPU cores are processing WUs
(Message 847387)
Posted 31 Dec 2008 by ![]() Post: Configuration: Just to add a note to this, when I had my Q6600 setup with 2 8800 GTS cards as a test, it looked like the Cuda tasks my have gotten mixed up about which GPU to use. I could not confirm this without more debug info from the tasks however. I like how Folding@Home does it, you lock a GPU to a task slot. |

if you think cuda is fast
(Message 846234)
Posted 29 Dec 2008 by ![]() Post: as far as to which is faster, they will switch back and forth as the new versions are released. ATI will release a card that is faster than the Nvidia latest. Then Nvidia will release another in a couple months that is faster than that. Same with Intel and AMD... The thing that may help ATI in the long run is the fact that their GPUs will do double precision FP (NVidia is single precision only). |

Someone please explain this
(Message 845653)
Posted 27 Dec 2008 by ![]() Post: A set and forget user might have a passively cooled CUDA card (the only one I have is) and not notice until it's too late that the CUDA app has over-heated it... The thing that is easy to overlook here is where the heat goes. I have 2 8800 GTS cards running Folding@Home and it keeps one card @ 81C and the other (with the partially blocked air intake) @ 89C. The problem is all the heat is not being blown out the back, everything inside the case heated up until I cooked 2 sticks of ram. (This unit is now running again with new ram and the case open and on it's side so the heat goes up into the air instead of up into the ram). Moral of the story- Keep an eye on the case temp along with the GPU temps. That being said, I agree that the GPU option should default to "OFF". The system needs to be checked and monitored after turning it on. |

Some testing tool for GPU needed
(Message 844821)
Posted 25 Dec 2008 by ![]() Post: Do you know any testing utility that checks validness of GPU computations? I haven't found anything. I have noticed that my system ram is right over a 70 drg C GPU however. It cooked the ram. More fans, and under-clocking the GPU right now. Makes me wonder if the errors we are seeing are ram failures caused by hot ram. If you find a way to load up a GPU and monitor it, I would keep an eye on the ram temp if you can. |

Problems switching to 64 bit client.
(Message 720619)
Posted 2 Mar 2008 by ![]() Post: Just to put in my 2 cents worth- I always install Boinc in it's own partition: 1)It writes data to it's program file area- very bad practice (Proper design is for separate program and data areas)! I avoid putting anything in the Program Files directory that uses that area for data. (If you upgrade to Vista it is not allowed- finally). 2) With Boinc in it's own partition, my backups on my C drive are much smaller (data is not changing constantly like Boinc apps do). |
