Firstly, thanks to everyone involved with making applications for ATi GPUs available. Running a Cuda card and a ATI card should cause no issues. I run a 465 and a 5670 in the same box and haven't had any real issues with running both builds You did choose the APP drivers from the ATI Download site didn't you? Have you tried running the CLInfo from the SDK sample kit to see what that returns? |

Ah, well, good to know it is possible. I always download the Catalyst drivers separately: display drivers, OpenCL drivers, and Catalyst Control Centre. The Windows XP 32-bit build of the APP SDK 2.3 don't seem to be available yet, and Raistmer's post on Lunatics suggests that the separate SDK installation isn't necessary, so I thought I would give the OpenCL applications another try, given that the OpenCL drivers are already included with the Catalyst package. There is definitely something installed in the '<Program Files>\ATI Stream\' directory. Edit: This is the host in question, with two failed Multi-Beam OpenCL WUs: 1795708180 1795723279 I never finished an Astropulse OpenCL WU (well, it never really started), I just revert to the Hybrid Brook version on those attempts.

In your System Properties>>Environment Properties>>System Variables page is there a ATISTREAMSDKROOT path set? On my Win7 x64 it's set to "C:\Program Filesx(86)\ATI Stream\" |

Yes, that's what I said in my first post. It's currently set to 'C:\Program Files\ATI Stream\', and the path is valid as best as I can tell manually. I certainly didn't put the variable there, so I'm pretty sure the OpenCL driver installation added it automatically. It seems like most people who are using the OpenCL stuff are on Win7. I plan on moving to Win7x64 at some point, but only when I really, really have to, like 3 GiB of RAM no longer being sufficient and/or some super-duper game is released that requires or works best in Win7. I don't keep up with the most recent games, though, so I doubt an upgrade will happen any time soon. Soli Deo Gloria |

Is their any chance of an SSE1 build for anyone like me daft enough to be still running an XP 3000 rig (or similar box) like me. It's not so much getting Raistmer to build a OpenCL SSE app, the bigger problem is getting OpenCL support on our Hardware, it could be that a SSE2 CPU is required, the system requirements there is a bit vague, SSE2 is required to run an OpenCL app on the CPU, but it doesn't really mention if SSE2 support is still required to run an app on the GPU, or it could be that the AGP hotfix drivers just don't support OpenCL, we need someone to come along with an SSE2 or better CPU, and have an AGP Radeon, Don't worry about the clocks going up and down if you're now got the Hybrid app installed, as the Hybrid app is mostly a CPU app, with a small GPU part, the GPU part not being used all the time, better to join a ATI GPU project like Collatz, do an app_info there, and adjust the count setting so both run at once, (like i have) Claggy |

I'm probably going to get a 6970 in the next week or so. I can start testing the apps then In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Thank`s for the info and help Claggy, i will have to take on another project to get best boinc use out of this card, i only got the 4650 in november as a last chance upgrade to keep the pc out of landfill for a little bit longer, so when i get it going fully i may as well overclock (stable & valid wu) to the limit :) it has turned out to be not such a good idea afterall, i dont intend to kill it but `live fast die young` ;) edit - off topic, Just had a look at your `computers` page, i still have my K6-2-550 oc600 ran it on freehal till last year, NCPUI project so still had a RAC over 1000 running 12 wu together. i will leave this tread now and just lurk :) |

Hi, did a quick test with my 4670 and thats what happened: <core_client_version>6.10.58</core_client_version> used the default appinfo data that came with the release notes. are there any other tweaks i could try ? latest drivers are installed. couldn't get the ati AP app running either. Regards |

new ati 11.1 drivers out. From the looks of it the APP version is now the "preferred" version. In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Hi, What OS do you use? I've seen such report before, but the reason is unknown. It's completely "CPU" based part (namely, app should wait for OS mutant object and report failure if this waiting failed). And specific config on you host? EIDT: what rights have user under that account science app running? Too low privilegies level will result in unability to work with OS objects like mutexes. Check whar user account BOINC uses to run app. |

Is the limited boinc_project account insufficient for running the OpenCL applications? As posted earlier, I didn't get the same error as sling, but I wonder if reverting to an admin-level account for BOINC is something I need to try. At present, neither the Astropulse nor the Multi-Beam OpenCL applications work for me on my WinXP32, Core 2, HD4850/GTX260 system. Soli Deo Gloria |

In the app_info.xml file are entries: <cmdline>-period_iterations_num X -instances_per_device X</cmdline> This is for both (MB + AP) ATI apps? Which values I should insert if I have a HD6850? I know what means instances_per_device, but what means period_iterations_num? Thanks! |

In the app_info.xml file are entries: No, that cmd line is just for MB. From Raistmer's Lunatics post (which he linked in the first post): -period_iterations_num <N> splits single longest PulseFind kernes call on N calls -period_iterations_num 1 (default value) If you see lags in GUI or even driver restarts - add this parameter with value >1 (integer numbers). i.e. if you experience problems increase that number. I assume you loose some speed though. Carola ------- I'm multilingual - I can misunderstand people in several languages! |

What OS do you use? Hi Raistmer, I am using Win7x64. Boinc tells me that it is running under the admin account. I have lots of time tonight and will try to figure it out. Thank you EDIT: this is going on now: mb_6.10...exe running eating up one full core, no activity on gpu though |

What OS do you use? I can't see what your computer stats are Sling. What GPU/CPU are you using? How are you measuring GPU activity? I keep an eye on GPU activity using an application called Afterburner (GPU overclocking app, but it has a lot of useful information on it too). Sometimes my GPU bounces around a lot, especially when only running 1 GPU application at a time. The ATI apps do seem to use a bit more CPU time than the NVidia apps, but nowhere near a full core. I'm not the guru that Raistmer is, but perhaps if it's something I've experienced in the past, I can help you. :) -baron_iv Proud member of: GPU Users Group |

theres something wrong, no question. i use a gadget which i found pretty accurate, the temp is low, core clock low (powerplay), one core nearly fully loaded with mb.exe. its a sapphire radeon 4670 btw. i have made my hosts public. reinstalled boinc client, driver update. no fancy xml config, only tried to disable the onboard graphics with <ati_ignore.... which worked. i'll give it another try tomorrow. thank you for your help so far. |

So how do the ATI cards line up vs Nvidia cards? Like Which cards are comparable to each other. just wondering you know |

It's not a SETI@home-specific comparison, but I find the comparison charts at Tom's Hardware to be a useful, rough, guide. Soli Deo Gloria |

My 5850 running at 850MHZ is comparable with a Geforce 250. The CPU usage is very low on my rig ~ 120 seconds. My wingmen mostly have double but it depends on the CPU. My X6 scales very good. With each crime and every kindness we birth our future. |
