Post: When this happens, getting the wrong kind of work, see if you can get the server log for that contact. To do this go to your list of computers and then in the rightmost column click on the datestamp for the last contact to display the log, post it here and maybe that can shed some light on why you are allocated work for an application you have not selected. |

Post: I don't speak for the project but I can imagine that it has to do with this being a test project for both applications and server software. As stated on the front page "Don't expect anything to work here"... |

Announceing where we should focus our efforts?

Post: Hi! Previously there used to be some sort of announcement when a new app version was released so that testers would know what's new and needs testing, could we have that back please!? I would think that announcing what testers should focus on would speed up things up so that new apps and functions can be brought over to Einstein. Likewise it would be nice to know when you deem a test completed so we could focus our resources on other tests or the real work over at Einstein. Thanks |

Post: Before aborting tasks that seem to be stuck I'd try 1) a restart of Boinc 2) a restart of the computer, if that don't help then maybe I'd consider aborting... |

Post: That's great news! As there's been no announcement of the release on the Einstein boards I'll give some feedback here instead. I've run some tasks on my HD4000 over at Einstein and so far all looks good, 3 have validated. Link to the host The only small problem is that the task are sent with instructions to use 0.5CPU+1GPU, this has the effect on my system that the GPU load as per GPU-Z is less than 20%. If I free one core by setting my prefs to use 87.5% of the CPUs then the GPU load goes up to about 85-90%. For now I'm running with an app_config.xml and using 0.5CPU+0.5GPU to run x2 thus reserving one core when there is task available, GPU load is 90-95%. |

Post: Thanks, it looks a lot better now as all recent tasks have the status valid instead of validate error! Hope we can get this sufficiently tested and released on Einstein soon. |

Post: I've started getting "Validate errors" on my S6 CasA tasks with version 1.05. I can't see anything suspicious in Boinc's event log or in the task stderr, but as soon as a validation is tried both tasks get the status of Validate error and to new task are created. Has something in the tasks changed that the validator can't cope with or is there some problem with the result files? Link to my S6 Directed Search (CasA) task. |

Post: I did a little more investigation. Drivers installed via Windows Update almost never have the extra parts required for OpenCL, CUDA or what not. It's always recommended to get the drivers from Intel, Nvidia or AMD directly. No problem with the GPU nr. being 0. Both my 660Ti and the HD 4000 is nr. 0 and it still works. |

Post: Happy to hear that you got it working! =) I agree that we're probably going to have to answer a lot of questions on the message boards about how to get it running if released on Einstein but at the same time I think it would be the first project to release a Intel GPU app that don't require the use of anonymous platform. There is some potential outside the group of more knowledgeable users that may benefit from the app as at least here in Sweden there is a market for cheaper laptops without a discrete graphics card, they only have Intel HD Graphics. Can't say anything about how big or small this group might be or if they are willing to use the GPU though... Now on to some more test results. I've been running my machine fully loaded with 8 CPU task, 2 BRP5 tasks on the GTX660Ti and 1 GPU task on the HD 4000 for the whole weekend, all seems to be working fine though maybe not at peek performance. I noticed that the BRP5 tasks where a bit slow and the GPU load on the 660Ti was about 10% lower than before I started running on the HD 4000. So I decided to reserve another core by setting my local prefs to only use 87.5% of the processors. This seems to have helped as the GPU load on the 660Ti have gone up to almost the same as before, maybe 2-3% lower than normal and on the same time the load on the HD 4000 is now on average 93% over a full task. I'm going to run like this for a few days to see how it goes. By the way anyone else that's tried this? Want to try but not sure how? Just ask and I'll try to help! =) |

Post: Holmis, I have a question for you: your system also has an NVIDIA GFX card (which, I assume, is used for the primary display?). I have a TV connected to the Nvidia card and as you thought it's used as the primary display. To get the HD 4000 detected by Boinc I have to connect it to a monitor and choose to stretch/clone the image to that monitor plus the monitor has to be turned on when starting Boinc. I don't have a dummy-plug so can't test that. I think the reason is power saving and the HD 4000 gets turned off if nothing is using it. Once the HD 4000 is detected by Boinc I can turn the monitor off and all works as it should. |

Post: Next test will be to run 2 at a time to see what happens. Did a test run with the help of a app_config.xml and set both the CPU and GPU usage to 0.5 to run x2 and still only reserve one CPU for support. GPU load was ~93-95% and run time went from just over 17 min running x1 to ~28 min running x2 so there was some gain. Note that I only ran the 2 task like this and then reverted to x1 again. I'd say lets get this running properly first and then look at how to run it optimally. |

Post:
Nice! I've been running this for since yesterday and so far I have 52 valid and 45 pending task. Only one is inconclusive and that's because my wingman got a validate error. So all looks good! Just to test I suspended tasks in Boinc so that only 6 CPU task where running and check GPU-Z and the load on the GPU went up to ~95% compared to 7 CPU tasks and ~85% load. Seems to me that the CPU doesn't respond quick enough to keep the GPU fully loaded. Next test will be to run 2 at a time to see what happens. |

Post: No, the app is for Windows, I'm running it on Win7 x64. Download the app from the post about standalone test but then follow the instructions about using a app_info.xml and cc_config.xml to get it running. Don't forget to rename the .exe or make the appropriate changes to the app_info. |

Post: Nice to see you got it running under Boinc, will definitely make it easier to test and validate! I've just completed the first BRP4U task and it took 18m30s on the HD 4000, the average GPU load according to GPU-Z was 76% and it varies between 75-85%. Link to BRP4U tasks on host #2267 As a note to other testers the <coproc_debug> log flag in cc_config.xml is not needed for this to work, what it does is tell you which coproc Boinc assigns a task to and then at regular intervals it confirms the assignment. As I was composing this the second task completed (18m21s) and validated against the Neon-app! =) Oh and by the way did my first standalone test "validate"? |

Post: Tomorrow I'll try with the system fully loaded on all 8 threads and the GTX660Ti. So I just did a short test with the computer otherwise fully loaded with 8 Einstein tasks on the CPU and 2 BRP5 tasks on the GPU, the result was as I suspected from experience with other OpenCL apps. The GPU load reported by GPU-Z dropped to ~20-25% and as soon as I suspended tasks in Boinc to free up one thread the GPU load returned to about 80%, so the conclusion is that this app needs one thread free to run at optimal speed. From comments on other projects' message boards this seems to be a driver issue when one runs OpenCL apps both on Intel and Nvidia GPUs. |

Post: The task has now been completed and no errors occurred, so looks good and well done! =) Total runtime was 2h21m59s and CPU time ~2m23s. I've zipped the result files and stderr.txt and can e-mail it if your interested. Tomorrow I'll try with the system fully loaded on all 8 threads and the GTX660Ti. |

Post: I would be grateful to hear about results of running the standalone test on an Intel HD 4000. The first preliminary result on my standalone test on my HD 4000 says that it's running and quite fast. I'm running this first test with Boinc restricted to 7 of the 8 threads on the CPU and 2 BRP5 on my GTX660Ti. GPU-Z is showing GPU load mostly between 80-85% with the occasional drop to 0% and some spikes up to ~90%, memory usage is around 350 MB of dynamic memory with a max of 417 MB. The first 1/8 finished in about 20 min if I'm reading the log in stderr.txt right! More to come when it's finished! Activated exception handling... |
