Excuse me? Zero Credit?
(Message 66170)
Posted 2 Oct 2022 by wateroakley Post: With one resent task the credit updated today, so the script appears to be running. With the latest price of 'leccy' and no tasks, i'd set the host to 'sleep' after an hour. Interestingly, the Linux VM and CPDN task has not complained or aborted with 'sleep'. I've now reset the 'sleep' setting.It used to be that the credit script was run only once a week early UTC Sunday. But I thought that had changed recently. Respond back to this thread if no credit shows up by Monday and we'll alert Andy to the problem. |

Future CPDN on Windows?
(Message 66156)
Posted 30 Sep 2022 by wateroakley Post: Is CPDN planned to be able to run on Windows 10 / 11 in the future? If not, could CPDN run in a Linux VirtualBox system?CPDN will run on different flavours of Linux VMs, including WSL and VirtualBox. This message link and thread https://www.cpdn.org/forum_thread.php?id=9025&postid=64962#64962 gives a rundown on using Oracle VirtualBox 6 and ubuntu 20.04 LTS: Make sure you find the correct 32 bit libraries for your Linux version: https://www.cpdn.org/forum_thread.php?id=8916 Please note the importance of pausing and managing M$ Windoze updates, otherwise the updates will routinely crash models. The VM has migrated quite happily to a newer Windows PC. I've also got a Mac Mojave VM running too, although the VM was unhappy after the migration. |

Posted 5 Sep 2022 by wateroakley Post: It worked for 21.10Hmm. Yesterday, I tried to make a new Jammy Jellyfish ubuntu 22.04 VM on our latest i7-8500 Optiplex PC, WIN10 with VirtualBox. The install wouldn't behave when I tried to install the 32 bit libraries. I've faffed around with SUDO commands and library versions without success. Any good ideas are welcome.? Today, I reverted to exporting the ubuntu 20.04 VM appliance, copying the export file to the new PC, and importing it onto the new VB setup. That worked easily. I've done the same export/copy/import for Apple Mojave . |

Posted 1 Aug 2022 by wateroakley Post: Layered software, such as VMs, does make for a more complicated life. With an ubuntu VM on VBox/Win10, the finger of blame points towards the automatic monthly Windows updates for the majority of our model crashes. From 88 cpdn models, 71 have completed, 14 have crashed during an unannounced Windoze update, 3 crashed during a hard reboot to recover an unresponsive Windoze. We now pause Windoze updates for as long as possible and once a month ungraciously close the ubuntu VM to do all software updates in one go. This seems to have improved the success rate.Another possibility, is that you're running Linux in a VM on a Windows machine. |

Posted 12 Jul 2022 by wateroakley Post: This WinDoze PC is running Oracle VirtualBox, both Linux (ubuntu) and MacOS (Mojave). From running with VMs: a minimum of 16 GB physical memory (preferably 32GB) to keep WinDoze and other applications happy. Replace the Hard Drive with a SSD.I'm using an older PC which is running Win10. I've not had any work packets for some time now and I'm wondering if there is a minimum spec required to participate.A number of people are using WSL to run the tasks from Windows machines. While tasks will run on most Intel/Amd processors less than ten years old, towards the older end of that range they will be quite slow and I wouldn't bother on a machine with less than 8GB of RAM. |

Posted 9 Jun 2022 by wateroakley Post: I am getting quite a few fails of late, with the error "CPDN process is not running", being a bit of a Linux n00b can someone let me know how to check if it is running / how to restart.The high resolution hadam4h '216' models here use 1.5GB per model versus 684MB for the hadam4 '144' models. Here, three 216's and one 144 are currently filling up the 8GB ubuntu VM memory to leave just 140MB 'Free'. Looking at your Windows host, 32 Processor with 32GB of RAM; and the Mint VM with 24 processors in 16GB of virtual RAM ... I'd suggest that you limit the CPU count for the Mint VM in VirtualBox (system settings) to 6 CPUs for 16GB of VM memory; or perhaps 8 CPUs for 24GB of VM memory. You'll need to power down the VM to make the VBox setting changes. You can further control the CPU granularity in BOINC manager: Options, Computing preferences. It's also important to turn off (pause) Windoze updates for as long as Doze lets you, as updates will crash models when you least expect it. |

Posted 5 Apr 2022 by wateroakley Post: Tasks have started appearing on the server. Linux only for this lot unless you use WSL or a VM of some description. In three minutes time when my box updates after the backoff from last attempt to get work I will be able to confirm that they are downloading OK..Fired up the ubuntu VM and four HadAM4 tasks have downloaded. Two tasks are running happliy and the other two are ready to start. The mojave mac VM is crunching it's four tasks in parallel, with the last two tasks ready to start. Both VMs seem happy to co-exist. |

Posted 16 Mar 2022 by wateroakley Post: I'm experiencing an odd behavior in BOINC running CM3s in VBox VM Mojave on Windows 10. The progress bar has stalled (values are stuck on a number and not going up) on all tasks but the Elapsed and Remaining times are still counting. No trickle ups in a couple of days even though before it was at least once a day. Suspend/Resume seems to get things going again. Has anyone experienced anything like this before?Sounds similar to two here. When they got to 100% and —- they cycled back to 99.98% then 100% and —. Wierd. The only option, for here, was to abort them. |

Posted 14 Mar 2022 by wateroakley Post: The newer machines are an awful lot cheaper to run than older ones in terms of compute per wattRetiring two quadcore PCs with hard drives for second-user i7 PCs with solid state drives has cut our annual 'leccy use by 1,200 kWh. The lower power cpus are 85% of the savings and hard drives are circa 15%. That's enough 'leccy for 4,000 miles in the EV. |

Running 32-bit MacOS Tasks on Linux with KVM
(Message 65273)
Posted 13 Mar 2022 by wateroakley Post: I've actually had better luck with just killing the VM entirely than trying to suspend tasks if I need to power cycle something - suspend/resume cycles are likely to kill 40-60% of the running tasks, and a power cut kills fewer. I'm trying not to do that, though - like all the CPDN tasks, they're best left running, non-stop, until completion.Today, this Windows host (running the mac mojave VM) froze after excel threw a wobbly. Power cycling the host and restarting the mac VM brought back all four running tasks. That's 100% better result than carefully closing down BOINC and the VM. |

Posted 10 Mar 2022 by wateroakley Post: @wateroakley@geophi I've adjusted the screen resoultion to 1920x1080: VBoxManage setextradata "macname" VBoxInternal2/EfiGraphicsResolution 1920x1080. After making the change, the mac screen window inside VBox fills more than the display and the mouse is laggy. Changing the mouse 'tracking speed' to 'fast' in 'System Preferences' doesn't make a big difference. Stopping the 'oregon trail' video, that apple had decided to play continuously, brought back the responsiveness! Two of the tasks are cycling at 99.98% for the remaining 1 minute 45 secs to zero and ---. ? When I suspend one of the two, the second task pauses at remaining time ---. It sits there until I resume the suspended task and then both will cycle again. Wierd?. Then when I restarted the BOINC manager, four crashed with 'computation error' and 'output file missing' in the event log. Note to self: "LEAVE IT ALONE". Four new tasks are running now. |

Posted 8 Mar 2022 by wateroakley Post: We now have passed one month since the last post, and apparently there is still no work for Windows PC's.If you are familiar with setting up VMs, installing macOS Mojave from the link that Les posted is straightforward. The only issue I've found is that the instructions do not mention screen resolution, which defaults to 1024x768. The VB management command for e.g 1920x1080 is: VBoxManage setextradata “macname” VBoxInternal2/EfiGraphicsResolution 1920x1080 |
