@uplinger here is link to a more detailed log: https://www.worldcommunitygrid.org/ms/device/...og.do?resultId=1589061657 and https://www.worldcommunitygrid.org/ms/device/...og.do?resultId=1589061726 Thanks in advance for all your hard work! I'm not sure what happened here, it looks like your computer and another intel gpu hung on a process. I would be curious to know if you have the screen saver on your machine enabled? Nothing specific about your machine from my end stands out as a problem. Do you by chance have some anti virus or malware program on your device that could be catching the GPU processing? Thanks, -Uplinger |

@TPCBF I would not necessarily call an 8T i7 call a "low power" machine. And the screen saver is the BOINC one I admittedly don't know much about Macs but I do know that running a screen saver on a low power machine/GPU can cause issues when crunching. Maybe disabling your screen saver might help.  with me just adding that the screen itself is being turned off after 5min of not being in use. And this machine is in fact much less used these days like for example the NVidia based Win10 box that is currently crunching along just fine, all while actually being used as a CAD workstation...Ralf  |

I was just guessing but FWIW I would still not run a screen saver while GPU crunching. JMHO

@Uplinger
No screensaver is enabled Webroot antivirus is installed but it isn't giving me any warnings about it blocking the application. CPU workunits run great :) |

I am sorry to having to jump in here but all my Beta-WUs are ending with Valid but Claimed/granted 0.00/0.00.
----------------------------------------Is there a place I can look to see why this is? One of the Valid Results is logged as follows: Result Name: BETA_ OPNG_ 0000076_ 00260_ 0--It looks good to me, but no points are displayed. Not that I care too much about Points, but I'm just wondering. Cheers aend   [Edit 1 times, last edit by aendgraend at Mar 31, 2021 8:51:16 PM] |

When loading the next batch of units would it be possible to get more than 4 at a time. I'd like to try various combinations of 3/4/5/6 at a time on my other machine with the Titan graphics card to see which combination best utilises the GPU. I found 1 & 2 at a time both left the card idle for periods. I think the sweet spot will probably be around 3 or 4, but would like to try 5 & 6 as well, just to see the result.
BTW don't lose sleep over not being able to easily grant points to old completed WU's. I'm fairly certain that all the WCG points I've collected to date wouldn't even buy me a single slice of pizza in the canteen at WCG HQ. So I don't think I'll miss those few extra ones terribly. |

Why is this beta task still using idle thread priority in Windows? Slows down GPU tasks when at 100% CPU usage. For app makers / compilers (not users), they could change the priority to get GPU task working faster on AMD GPU and maybe intel GPU. Higher GPU priority can possibly ix time exceeded errors on intel GPU? https://boinc.berkeley.edu/trac/wiki/BasicApi#GPUandcoprocessorapps
Thank you for checking the log file. The integrated graphics can be slowed down by one or more of the following:If true, that is strange, the same 2 computers ran previous versions of this beta just fine. The computers have not had any changes to them. Win 10 64bit, Intel 6500t w/ 530 iGPU. GPUz says the OpenCL version is 2.1 - Limited package power. - CPU using too much memory bandwidth, iGPU use shared system memory. - Overheat throttling - Thread priority for GPU too low. Why is this Beta GPU still using idle thread priority? Process hacker tool can see and change thread priority while running, but thread priority manual changes by end user don't stick around on next tasks. Users can change the app to auto pause one of a CPU task by setting beta29 CPU usage to 1 to free up CPU usage whenever this GPU app runs. C:\ProgramData\boinc\projects\www.worldcommunitygrid.org\app_config.xml <app_config>Then in Boinc manager, Options, read config files, for changes to take affect immediately. GPU usage, if set to 0.5, will allow 2 GPU task to run at the same time. CPU usage of 0.1 or 0 will just make it not pause any CPU tasks. |

I've had the same issue. My old 7970s easily run 4 at a time but have not been able to keep 4 at a time running after the initial 4 start. Your titan will probably have no issue with 4 concurrently, maybe more, just make sure that each task has a full CPU to use.

I found this message in the log:
"Task BETA_OPNG_0000302_00293_0 exited with zero status but no 'finished' file" Result status: Valid |

Well, that was a bit of a roller-coaster. With 5 computers, 10 GPUs, I've got 54 pages of results to look through, and 720,000 BOINC credits added to my account tonight. The NVidia GPUs seem to have behaved flawlessly, both under Windows 7 and Linux Mint. But I do have a couple of things to look into tomorrow.
A couple of the Windows machines were allocated just one CPU, non-Beta, task each. I thought I'd turned that off, but I'll check the settings yet again in daylight. And I still have a lot of problems with Intel GPUs (Windows only - I'm not even trying under Linux). My tasks often stall and make no further progress: one from this batch has made it to 50% (real progress), but some are still only showing pseudo-progress, not having completed even a single Autodock task. I've suspended them so they won't time-out overnight. The Grumpy Swede and I are going to compare notes: mine are i5-4690 CPUs, and the HD 4600 Graphics have 1298 MB vRAM. His are i7-4790K CPUs, HD 4600 with 1400 MB vRAM. That memory difference may be significant. More tomorrow. |
