New Modfit Runs
(Message 62822)
Posted 11 Dec 2014 by Mumak Post: Any chance to look at the high error rate of current Modfit units ? I have no issues with the default MW application, only a few errors during several days. Today I gave Modfit another chance, but after ~1 hour I have disabled them again - 10 invalids during such a short period and that's probably not the end. |

Posted 21 Oct 2014 by Mumak Post: I'm too seeing a higher error rate of the Modfit since a few weeks (several dozen invalids per day). Had to opt-out... |

(Message 62313)
Posted 11 Sep 2014 by Mumak Post: All the ps_modfit_16TestStars... tasks are failing on my (otherwise) stable machine (2xHD7950). I never had big issues with MW@H tasks, but this seems to be a problem in those units. I have to disable the entire ModFit set because of this. I just realized this is already reported in the News section.. You can delete this then. |

Posted 8 Apr 2014 by Mumak Post: Maybe posting a few lines from the log (BOINC start with GPU IDs and work request/result) might help to understand the problem. |

Thermal issue with OpenCL
(Message 61477)
Posted 7 Apr 2014 by Mumak Post: Also, projects like this, which use double-precision load the GPU execution units higher, so that causes additional heat. In my case (HD7950, R9 280X) the GPUs run ~10 C hotter than on other projects with single-precision math. You might need to undervolt your GPUs if possible. I do this too, otherwise they would run too hot. |

Thermal issue with OpenCL
(Message 61377)
Posted 10 Mar 2014 by Mumak Post: I don't think it's possible to run the GPU at 120 C. What tool do you use to monitor it? You might try to undervolt it. I do this with my 7950's which had VDDC=1.25V default, but fortunately have digital PWMs, so it's fairly simple to change the voltages. |

Posted 25 Feb 2014 by Mumak Post: I don't think that it's possible to utilize the NVIDIA GPU well using OpenCL. NVIDIA drivers are just not well optimized for OpenCL and they don't care about it either... |

Posted 24 Feb 2014 by Mumak Post: I agree ;-) I'm still checking and tuning few things there, so it might change.. BTW, that cooling solution works pretty nice - 68 C max (with a side fan in the case). Without the side fan, ~71 C. |

Posted 24 Feb 2014 by Mumak Post: OK, so the new Gigabyte 280X is up and running: There are 2 GPUs in the machine: #0 - HD7770 @ 1020 - Left graph column #1 - R9 280X @ 1100 - Right graph column Tasks: http://milkyway.cs.rpi.edu/milkyway/results.php?hostid=534385&offset=0&show_names=0&state=4&appid= So the slowest times belong to the HD7770. For the 280X and slower units, I see times 70-75 secs so far... |

Posted 24 Feb 2014 by Mumak Post: and I checked out the HWinfo site but it's not updated as frequently as GPU-Z or SIV64X but thanks for the tips guys. What?! I released a new version a week ago and will release a new Beta tomorrow ;-) |

Posted 23 Feb 2014 by Mumak Post: I forgot to add, that some GPU monitoring tools tend to round-up the actual GPU clock (over a period of time) on some later AMD families. HWiNFO on the other hand reports the actual precise clock. |

Posted 23 Feb 2014 by Mumak Post: if you want something that'll substantially outperform a 7970/7970GE, you'll have to upgrade to a 290 or a 290X... But not for MW@H (double-precision), since the 290 (Hawaii) has crippled DP performance. But this is something we all know... WES - you can use HWiNFO and log all sensor values to see at which exact clock it is running. |

Posted 22 Feb 2014 by Mumak Post: I'll utilize the CPUs for WCG and T4T. 75-80 C? I hope not so high ! My 7950's with STOCK settings were reaching power limit and overheating on MW. Then I noticed the default max VDDC was set to 1.25V, which is way too high. So I reduced it. Now at full DP load the VDDC is ~1.07V and temps are ~65 C. |

Posted 21 Feb 2014 by Mumak Post: Will see the next week with a new Gigabyte GV-R928XOC-3GD REV 2.0 ;-) Boost 1100 MHz. Also what temperatures will the WINDFORCE 3X cooling maintain under sustained DP load... Will also get a new Dual Xeon workstation soon. I was hoping it will be fitted with a Tesla (full DP), but it wasn't possible :-( |
