I was never able to replicate that on my systems. *shrug*I can pop one off in a heartbeat. All I have to do is restart the 9 GPU GDDR5 machine and usually at least one GPU will Miss All Pulses on the first task. I need clarification. Does the machine have to be power restarted or simply restarting BOINC? Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I noticed that, but thanks for checking. I was going to let it run for a day as is to make sure it was not random. Seemed 440 drivers worked last round I sent you several PM's apprising you of the problem also with your current drivers.

Seemed 440 drivers worked last round He has 2 different Linux hosts one with [2] NVIDIA GeForce RTX 2070 SUPER (4095MB) driver: 435.21 who last contact was today and the other with [2] NVIDIA GeForce RTX 2070 SUPER (4095MB) driver: 440.48 OpenCL: 1.2 who last contact was 8 fev. That is the problem. |

no, i reformatted and reinstalled Linux those are the same machine but with different loads of linux. The drivers that came with Mint were not the same as Ubuntu. |

I reverted back to cuda90 for now, do not want to mess with video drivers tonight |

About the removal of the checkpoint. FYI I made some changes in the code and thanks to Ian help with the compile process, we have an experimental version of the 10.2 mutex builds running with the checkpoint removed. Will wait Richard wake up to guide us to how to test to see if all is working. Fingers crossed while we wait the beer if flowing. |

Restart/Reboot the Machine. It also needs to be a machine with mostly GDDR5 GPUs., BTW, Petri isn't using any GPUs with GDDR5 vram. I bought My 1080Ti because another user wasn't having the Problem with His 1080Ti and I had tried everything else. He also had the Same Problem with His 750Ti Missing Pulses where his 1080Ti doesn't, https://setiathome.berkeley.edu/show_host_detail.php?hostid=8424399I need clarification. Does the machine have to be power restarted or simply restarting BOINC?I was never able to replicate that on my systems. *shrug*I can pop one off in a heartbeat. All I have to do is restart the 9 GPU GDDR5 machine and usually at least one GPU will Miss All Pulses on the first task. I'd suggest a machine using 1070s and lower for the test, with at least one GPU not connected to a monitor, it's usually the GPU(s) not connected to a monitor that have the problem immediately. Sometimes on a Mac the GPU connected to the monitor can run hours, or days, before it starts missing All pulses. |

OK, thanks for the instructions. I wanted to test on a machine with your necessary criteria. I have a host with a 1070 Ti and a 1070 which meet the criteria of no monitor attached. The 2080 is attached to the monitor. I did not find any missing pulses on the 1070 upon restarting BOINC. But that was after updating the drivers to the latest 440.59 and restarting the computer. This task was started right after the host was restarted. https://setiathome.berkeley.edu/result.php?result_name=blc75_2bit_guppi_58693_08905_HIP98801_0143.7855.818.22.45.224.vlar_0 In cudaAcc_initializeDevice(): Boinc passed DevPref 3 setiathome_CUDA: CUDA Device 3 specified, checking...

My host has 2x 2070 + 2x1070 with no monitor attached to both 1070`s . Never see that too. Will keep an eye on that. Could be something related to the MAC hosts only? Who knows? |

How many times? Usually less than half of My cards show the problem after a reboot. I'd suggest trying it with just the lower end GPUs. The Mining machine Is Not a Mac. Juan was the First to post about the problem long ago when he was just running 1070s in Linux. Remember that Juan? |

Lowest end card I own is a 1070. Never noticed the problem ever after what . . . . . couple of years now. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

How many times? Usually less than half of My cards show the problem after a reboot. I'd suggest trying it with just the lower end GPUs. I remember something about a long time ago. But IIRC was related to the way the reschedule kills the process leaving a closed slot sometimes or was another program not remember. Was solved by adding a deleting round of the slots. Did you remember the post? Just to refresh my memory. You know i an old man who easy forget everything. |

Not just a restart of BOINC. He did not mention a complete cold boot from power switch off.

I've never seen that problem on either of my 2 dual GPU rigs, but sudden power downs 1-2 secs after starting a task will produce a corrupt header error and that is all I get on restarting (though that can happen on either 1 of the cards).He said a power restart of the host. Not just a restart of BOINC. He did not mention a complete cold boot from power switch off.How many times? Usually less than half of My cards show the problem after a reboot.

I trying to refresh my memory and remember, the problem i report only happening on my host when the 4 GPU (4x1070 at that time) where enabled and i use an slow HDD. The process was ended before the crunching programs was able to finish the slot housekeeping cleaning process at the end of it. IIRC only one other seti user has the same problem at that time and his host was very similar to mine. |

This was when the problem was first being identified, at that point I thought it was just My machine. I later found my other machines had the same problem once I turned the monitors on and started actually using the machines. juan BFP Message 1953194 - Posted: 1 Sep 2018, 11:37:03 UTC I've never seen that problem on either of my 2 dual GPU rigs, but sudden power downs 1-2 secs after starting a task will produce a corrupt header error and that is all I get on restarting (though that can happen on either 1 of the cards).He said a power restart of the host.

you also once blamed this issue on a web browser. https://setiathome.berkeley.edu/forum_thread.php?id=81271&postid=1954273#1954273 Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |
