I wonder if it could be specific to notebooks?
09-Aug-2011 16:07:08 [---] Starting BOINC client version 6.12.33 for windows_x86_64
09-Aug-2011 16:07:08 [---] OS: Microsoft Windows 7: Home Premium x64 Edition, Service Pack 1, (06.01.7601.00)
09-Aug-2011 16:07:08 [---] NVIDIA GPU 0: GeForce GT 420M (driver version unknown, CUDA version 4000, compute capability 2.1, 994MB, 128 GFLOPS peak)

Hi Jason, nvAPItest shows the correct driver version as you can see. 267.21 is the same as gpuz0.5.4 show. Your program does it right.  |

My ION shows the driver correct
11.08.2011 10:16:27 Starting BOINC client version 6.10.60 for windows_intelx86
11.08.2011 10:16:28 NVIDIA GPU 0: ION (driver version 27032, CUDA version 4000, compute capability 1.1, 242MB, 35 GFLOPS peak)

I wonder if it could be specific to notebooks? If mine works, then it's specific to Boinc  (i.e. they aren't using the same mechanism, I I'll have a proper look what the use a bit later. strange they would link with nvApi and not use that. ) |

... I think it would be better the app choose the GPU, than jiggle with profiles.
my two cents.... yeah optimus has differences when you need Cuda + Graphics (DX or OpenGL), which we didn't ever need to worry about. I am curious how Boinc tells the driver version now, as it looks to sometimes give the same proper result & sometimes weird 'unknown'. I'll look into it, as really it's likely the server needs to know the proper driver version one day, to send the right applications. |

Looking at my host list, it's only the 420M notebook which is missing a driver. The only other difference which would be worth considering is that the notebook is the only 64-bit host in that list - but there are enough 64-bit users around to rule that difference out. Oh, and notebook GPUs are almost by definition OEM variants - GPU-Z has problems getting memory usage from this one, for example. |

Mine's 64 bit, so that's eliminated as a source. Now that I'm curious I'll have a bit of a dig in the Boinc sources & give you another source patch... LoL

I'll be around for a couple of hours to run any instrumented test apps, but I've promised to go out on a call at 13:00 UTC. |

I'm off to work anyway. Only a few hours tonight. Heinz has just got me curious now, so I have to find out  [Later:] Looks like some ancient nvapi.lib (both 32 & 64 bit) in the Boinc Trunk. I'll have a look if simply bringing them up to date is easy enough, and helps (or not). Boinc trunk 32 bit version nvapi: - name: nvapi.lib - size: 10.1KB Mine: nvapi.lib, 80.9KB Boinc trunk 64 bit version nvapi: - name: nvapi.lib - size: 10.7KB Mine: nvapi 64.lib, 116KB |

BOINC is still trying to support Win2k, likely the most recent versions of that DLL don't. Time marches on...

I'll add that the nvApi interface is 'supposed' to be forward & backward compatible. I guess it seems to work for most of us, but these freaky laptop guys just never do what they are told... |

Awaiting 10 Mio from pg in the next days...
Got it gt540m_10Mio_primegridcrunching since 20 Feb 2011 | 15:48:17 UTC, including 14 days vacation, and normal use of the laptop ~~~~~~~~~~~~~~~~~~ Total 193,944,311.28 Precalculation says: 200 Mio total <--- Ziel wird in 86.68 Tagen am 6.

GT540m and ION get some respectable numbers (10Mio btw 1.4Mio)...by running optimized cuda apps, no cpu-apps used. heinz modify: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Happy Birthday Als der Rechner auf den Schreibtisch kam 30 Jahre Personal Computer von Alfred Krüger Der Personal Computer feiert Geburtstag.
