(Message 67934)
Posted 21 Jan 2023 by wateroakley Post: I've had a couple of these errors on an ubuntu VM. The advice from Glenn was to allow 5GB per IFS task and run a maximum number of openIFS tasks equal to n-1 physical cpu cores. To avoid any unexpected compatibility issues I also dropped running any other projects. With a 4-core i7 cpu and 24GB memory that would be 3 concurrent openIFS tasks; with memory headroom and one physical cpu core for whatever else the computer system wants to run. This w/u https://www.cpdn.org/result.php?resultid=22269116 failed with a most informative error |

Posted 13 Jan 2023 by wateroakley Post: 23:15 GMT 13 Jan 2023. Here, the backlog of uploads has just cleared a few minutes ago. There is about six days of openIFS work cached with deadlines from Sat 21 Jan 2023 to Mon 23 Jan 2023. They are followed by the next openIFS task deadllines from 10 to 12 Feb 2023. Provided everything is left running 24/7, it all looks doable here, within the deadlines. Ok. do you have a rough idea of how many extra days you need? I've already raised this with CPDN following Richard's message about the grace period. I'm in a meeting with them on Monday so I can talk about it then if you give me a rough estimate? |

OpenIFS tasks : make sure boinc client option 'Leave non-GPU tasks in memory' is selected!
(Message 67640)
Posted 13 Jan 2023 by wateroakley Post: ktf I’d concur with Andrey. 8GB ram is less than the minimum recommended for Ubuntu (4GB) and a current openIFS task (about 5GB). Without enough ram, your three or four cpdn tasks will get continually sent to disc whenever a swap occurs - that’s a recipe for crashes. One openIFS task may be ok. From experience of Ubuntu and cpdn in a VM, it’s not going to be happy with anything less than 10 or 11 GB ram. Your celeron cpu should support 16GB ram, subject to the mobo and chipset limitations. That should let you run one or two of the current openIFS tasks. You can set the BOINC options to limit the cpu count to nn% and thereby limit it to one or two tasks. However, the upcoming ram requirements, that Glenn has indicated are much higher for future models, are going to exceed the maximum possible ram of your celeron cpu. H. |

Posted 12 Jan 2023 by wateroakley Post: I'm OK with the current mix of task run time, file size, file numbers and our upload broadband speed, even with the outage, it's manageable for me. If needed, I can increase the VM disc for ubuntu to over 900GB. If it really troubles people to see so many uploads building up in number we can modify it for these longer model runs (3 month forecasts). |

Why does this task fail ?
(Message 67508)
Posted 10 Jan 2023 by wateroakley Post: So ...The openIFS thread discusses the 'file absent' problem. If you take a look at your /var/log/syslog file for the entries around the time the task finished, there should be a mention of 'oifs_43r3_ ... file absent'. Have a look at what was happening immediately before the crash. Here, other software in the ubuntu VM was complaining and subsequently the openIFS task threw a 'file absent' wobbly. The key message from Glenn was to make sure to 'Leave non-GPU tasks in memory while suspended' (tick the box in 'Boinc - computing preferences, Disk and memory').. Since i've done this, the only two task crashes have been due to a power brown-out a couple of days ago. |

Posted 2 Jan 2023 by wateroakley Post: We've been runing Virtualbox 6.1 with ubuntu 20.04.1 VM for 18 months and Mac Mojave VM for 9 months. 1. i7-3770 WIN10 host with 32GB of physical RAM. When sizing the VM memory, the Windoze host will need a minimum of 8GB RAM reserved for Windoze to play in. You'll need at least 24GB of physical RAM, peferably 32GB. In practice, 16GB physical RAM was insufficient. The on-line tutorials all create a very small VM disc, far too small. If you need to make a much bigger linux VM disc, try GParted. About 40-100GB has been good so far. The run-time cpdn crash issues were (in part) from Windoze updates unexpectedly rebooting the host. The answer is to pause Windoze updates for as long as you can and manage the WIN10 updates manually. 2. i7-8700 WIN10 host with 40GB of physical RAM The ubuntu and Mojave VMs were migrated to this host . VirtualBox 6.1 is happily running the migrated ubuntu 20.04.1 VM with BOINC/cpdn. Increasing the 40GB vdi disc size in VirtualBox to 100GB created a 990GB VM disc partition. Oops, fat fingers had added an extra zero. There is no way to reduce the VM disc partition size in VirtualBox without creating a new vdi and moving the VM files around. Set the number of VM cpus to N-1 physical cores. Tick 'Leave non-GPU tasks in memory while suspended'. Edit: With the VM running 5 cpdn openIFS tasks, Resource Monitor reports 39GB Physical Memory in use and 1.6GB of cache. The indicated requirements for upcoming openIFS tasks, says that more physical RAM will likely be needed. Unfortunately, the new host does not like the Mac Mojave VM. Neither the migrated copy nor a fresh install get beyond starting the shell. I suspect it's unhappy with the EFI boot? Any suggestions on fixing this are welcome. 3. Quad-core Q9650 with 8GB physical RAM. We got the ubuntu VM and BOINC/cpdn running. However, it ran one cpdn task, very slowly. QED: don't bother. |

Posted 22 Dec 2022 by wateroakley Post: If you could kindly check your /var/log/syslog file for an entry around the time the task finished. There should be mention of 'oifs_43r3_' something being killed. Let me know what there is.Glenn, as requested, I've pasted the syslog file below, from the time that the WU 12168039 task_o (https://www.cpdn.org/result.php?resultid=22252269) appears to behave (at 05:51am with zip 42 upload) to when it failed (immediately after zip 43) and decided that it had finished at 06:02am. Nothing being killed, but other things do start to go wrong around 05:55am. The i7-8700 host has six physical cores, 12 virtual cores, The VirtualBox ubuntu VM is configured with 6 cpu and running 6 cpdn tasks. Boinc preferences are configured to use 100% of the cpus and 'Suspend' when non-BOINC cpu is above 75%. The VM is only used for boinc/cpdn work. Should I drop the VM back to 5 CPU? Interestingly, today we had a power brownout at 1pm and the PC unceremoniously crashed. After restarting, all six IFS tasks restarted successfully :)) That's a first - I've rarely had 100% restart success for non-IFS tasks after a crash. syslog Dec 21 05:51:27 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:51:27 [climateprediction.net] Started upload of oifs_43r3_ps_0395_1982050100_123_951_12168039_0_r1962384054_42.zip Dec 21 05:51:27 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:51:27 [climateprediction.net] Started upload of oifs_43r3_ps_0401_1982050100_123_951_12168045_0_r692153421_41.zip Dec 21 05:51:47 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:51:47 [climateprediction.net] Finished upload of oifs_43r3_ps_0395_1982050100_123_951_12168039_0_r1962384054_42.zip Dec 21 05:51:49 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:51:49 [climateprediction.net] Finished upload of oifs_43r3_ps_0401_1982050100_123_951_12168045_0_r692153421_41.zip Dec 21 05:52:52 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:52:52 [climateprediction.net] Started upload of oifs_43r3_ps_0425_1982050100_123_951_12168069_0_r777869862_42.zip Dec 21 05:53:04 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:53:04 [climateprediction.net] Finished upload of oifs_43r3_ps_0425_1982050100_123_951_12168069_0_r777869862_42.zip Dec 21 05:54:52 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:54:52 [climateprediction.net] Started upload of oifs_43r3_ps_0422_1982050100_123_951_12168066_0_r1003053545_42.zip Dec 21 05:55:03 ih2-VirtualBox boinc[834]: 21-Dec-2022 05:55:03 [climateprediction.net] Finished upload of oifs_43r3_ps_0422_1982050100_123_951_12168066_0_r1003053545_42.zip Dec 21 05:55:08 ih2-VirtualBox dbus-daemon[992]: [session uid=1000 pid=992] Activating via systemd: service name='org.freedesktop.Tracker1' unit='tracker-store.service' requested by ':1.3' (uid=1000 pid=970 comm="/usr/libexec/tracker-miner-fs " label="unconfined") Dec 21 05:55:08 ih2-VirtualBox systemd[917]: Starting Tracker metadata database store and lookup manager...

Posted 21 Dec 2022 by wateroakley Post: It's possible AMD chips are triggering memory bugs in the code depending on what else happens to be in memory at the same time (hence the seemingly random nature of the fail). Hard to say exactly at the moment but it could also been something system/hardware related specific to Ryzens. I have never seen the model fail like this before on the processors I've worked with in the past (none of which were AMD unfortunately). I am tempted to turn down the optimization and see what happens....

Posted 3 Dec 2022 by wateroakley Post: 'There *is* an issue with restarts. The model process itself restarts just fine if the client/machine is shutdown and restarted. However, the controlling wrapper code then appears to be miscalculating where the model is in the forecast and this leads to the 'missing file' problem that's been reported.Thanks Glenn. After a lot of hit and miss tasks, the last six 'uninterrupted' OpenIFS tasks here have completed! |

Posted 1 Dec 2022 by wateroakley Post: [ADSL people: knowing your bottleneck is network, are you happy just reducing the no. of tasks running concurrently? What's your sustainable data-flow rate you would be happy with (give me a number to work with).The broadband uplink here is 12Mbps and downlink at 40Mbps. It's pretty consistent at that speed. The event log showed that uploads from six concurrent tasks over the past few days are taking 12-15 seconds each, which is not giving a network headache. A single new task download (3 jf_c... files) is less than two minutes. |

Posted 1 Dec 2022 by wateroakley Post: To get the openIFS tasks to run on this VirtualBox ubuntu host: https://www.cpdn.org/results.php?hostid=1512045, I increased the ubuntu VM disc partition from 40GB to 100GB (gparted). After five early openIFS successes, the subsequent tasks have crashed with one error or another. The event log has reported a lot of 'file absent' records, with no obvious local reason that I can see, This afternoon I've increased the memory allocated to the ubuntu VM from 28GB to 32GB and reduced cpus (tasks running) from six to four. On a positive note, after the reboot all the suspended tasks started up successfully! |

Hardware for new models.

Posted 10 Nov 2022 by wateroakley Post: Even so, about 100W is nothing. A fridge gives that off. Open the window.Are you sure? An E-rated American style fridge-freezer is about 350 kWh a year, that's 40W. A B-rated fridge is about 137 kWh a year, or 15W. Our i7-cpu based PCs pull over 100W without the monitors, about 900kWh a year. The waste heat from two PCs is warming our home office today, very slightly. |

Posted 30 Oct 2022 by wateroakley Post: My UBUNTU 20.04 Laptop R7-5800H with 16 GB ran a single HadSM4 at N144 unit which errored out after six minutes with the following report. Was this due to missing libraries which I meanwhile installed?The work unit will have crashed with NEGATIVE THETA due to an unfortunate choice of initial conditions. The crash is not due to missing libraries. |

Windows-based tasks?
(Message 66195)
Posted 16 Oct 2022 by wateroakley Post: I took a break from Climateprediction some time ago, as there appeared to be no Windows-based tasks available. Now retried, for a week, again no joy. Should I let it be?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 ubuntu VM has migrated quite happily to a newer PC with Windows 10 and VirtualBox. I've also got a Mac Mojave VM running and posted details on how to install it here: https://www.cpdn.org/forum_thread.php?id=9124&postid=65231#65231 |

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. |

Posted 30 Sep 2022 by wateroakley Post: Is CPDN planned to be able to run on Windows 10 / 11 in the future?
