And this lines. GPU not found: type=NVIDIA, opencl_device_index=1, device_num=-1 WARNING: boinc_get_opencl_ids failed with code -1 OpenCL platform detected: NVIDIA Corporation WARNING: BOINC supplied wrong platform! With each crime and every kindness we birth our future. |

Shut down BOINC and delete the Compute Cache. It is located at /home/{username}/.nv/ComputeCache Delete the files and folders in the Compute Cache folder. You could reboot the host for good measure too to get a clean copy of the Nvidia drivers installed. The Compute Cache contains the compute kernel primitives for the applications. If they are corrupted or missing, it could cause your errors. Once you restart BOINC the compute kernels will be regenerated.

It is located at /home/{username}/.nv/ComputeCache Sorry couldn't find that. Looking at all the lines that Mike pointed out it looks like the problem with the riser again where it suddenly doesn't detect the card. Hence the 142 "waiting to run ". I will see if there are any better risers around. |

Do you have the opencl drivers installed? I can’t see your systems since they are hidden. What is the output of clinfo? Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

It is located at /home/{username}/.nv/ComputeCache {username} is just the stand in for your user name. The .nv directory is hidden and needs to be shown by toggling the Show Hidden Files in the File Manager. So for example my ComputeCache is located at /home/keith/.nv/ComputeCache Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Do you have the opencl drivers installed? See the bottom of my first post, the answer is yes and I have already successfully completed AP's |

Ah I see. You definitely had a card crash. Check the std_err output of your v8 tasks also. https://setiathome.berkeley.edu/result.php?resultid=7884480804 You can see it trying to use a card and failing over and over until the other card becomes available and it fails over. What kind of system is this that you need risers for only 2 GPUs? Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

My question is whether limiting the 1060 to 60 watts and using PowerMizer = 1 are at odds with each other. The GPU seems to run just fine like this. If you don't pass any value to the PowerMizer parameter, the host boots up the gpus in Adaptive Power mode:Mode 0. You can set the values to 0,1 or 2. 1 sets to Prefer Maximum Performance which is not the one to use if you are having troubles cooling the card. A value of 2 sets the PowerMizer to Auto. I've never found a good explanation of the difference between Adaptive and Auto. Has something to do with how aggressively it downclocks the card for power savings especially for battery powered laptops.

Can I mix a AMD R260x with the NVIDIA Quadro P2000 ? Will this cause issues, do I need to change anything in the config files? |

Can I mix a AMD R260x with the NVIDIA Quadro P2000 ? Will this cause issues, do I need to change anything in the config files? Should be doable. You will just have to have both types of drivers loaded. The numbers of task per card would depend on the OS and the application. So setting up different parameters for each card would be more involved than a simple blanket configuration. Don't know if those two cards are similar enough in compute power.

What kind of system is this that you need risers for only 2 GPUs? Er a cheap and cheerful one, you know you might have seen them, ordinary PC boards, one full length PCIE 16 slot only. This particular board was the only new one I brought for my Linux conversions. Oh yes and my GPU's are all second hand as well. |
Ian&Steve C. Send message Joined: 28 Sep 99 Posts: 4267 Credit: 1,282,604,591 RAC: 6,640 |
Ah so you’re using a splitter on the only PCIe slot. I get it. No issue with second hand cards. Almost all of mine are second hand also. Else I wouldn’t have so many haha. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

I remembered reading in the fora about issues with the two different vendors OpenCL drivers stepping on each other. So you might have difficulty keeping the Nvidia OpenCL drivers installed along with the AMD OpenCL drivers. And vice versa. Seen most of the issues over at Einstein. Never dealt with AMD before so I am of no help. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I certainly had that issue when I tried to run a gtx 750ti or two on a AMD 2400g motherboard trying to crunch with the iGPU and the NVIDIA's. Through up my hands.

Quick question Apparently there has been a problem with some older messages links to Tbar's All-in-One: http://www.arkayn.us/lunatics/BOINC.7z Should get you what you want. Tom A proud member of the OFA (Old Farts Association). |

Quick question . . I noticed Tom's recent response to this message but was thinking that with the age of the original message you have probably sorted it out by now, am I right? Stephen ? ? |

Quick question I quoted for a context in case someone like the person I was PMing with entered the end of the message thread. I hope the original question as fully answered but couldn't find a direct reference to Tbar's All-In-One aka: AIO so I thought I would refresh that link.

Quick question . . Sorry Tom, I wasn't having a dig at you, I was just hoping it had been sorted out. I just didn't want to seem too interrogative or accusative. But it certainly doesn't hurt to have a current link available. Stephen < shrug> |
