Post: Until we get more experience with volunteers running these high memory apps I think it makes sense to restrict it to a single task for now. We can change it later in light of experience.LHC's ATLAS tasks at 10GB are the biggest I know of. But that's 8 threads, so you don't get people trying to run huge numbers of them. Are yours going to be single threads? YOYO@home ECM/P2 tasks take at least 11 GB per task, single thread. Which is why I stopped running them on my 32 GB machine and limit them to just 3 at a time on my 64GB machine, they are real memory hogs. Conan |

Post: Although not related to new work but following on from the last couple of posts, CMDock uses a wrapper and it shows under Linux, I believe that YAFU also uses a wrapper and possibly YOYO, SRBase, TNGrid? and a few others. In some cases it is needed due to the type of programme being used or the code it has been written in. A few other projects also use a "Trickle up" method to keep the Server updated with progress (Primegrid is one) and some of these projects need a wrapper for this purpose. Conan |

Server Status page questions
(Message 68604)
Posted 19 Mar 2023 by Conan
Post: I have also wondered about the server page. UK Met Office Coupled Model Full Resolution Ocean has had 927 tasks "in progress" for many months but I have seen no indication that any have been returned and the number never changes. Weather At Home 2 (wah2) (region independent) has 4,731 tasks in progress again for many months and again I have not seen any activity with this either (maybe 1 came back 4 months ago but can't be sure). What is happening with these work units? Conan |

The uploads are stuck
(Message 67538)

Post: Yes I am still seeing "connect(): failed" messages on all upload tries. It has changed to "transient HTTP error" now so still not working here yet (Australia). Server Status has not changed yet, still showing nothing. Conan PS: Some files are now moving, so possibly due to the load, some fail then must retry later, others are going through, some as low as 17 kB/s to as high as 1,700 kB/s. |

Post: Yes I am still seeing "connect(): failed" messages on all upload tries. But I still have 4 work units running and I am no where near filling up any disks, so no problem here. Conan |

Tasks failing on Ubuntu 22

Post: If you changed the option to "leave tasks in memory" but did not read the file to update BOINC with the change it may not work until it is read. Restarting BOINC would also read the file. Conan |

Hardware for new models.
(Message 67296)
Posted 4 Jan 2023 by Conan
Post: I saw some test results with the AMD RYZEN 5950X, RYZEN 7950X, INTEL 12900 and INTEL 13900 (I think they were the model names). When all under full load for what ever test they were doing RYZEN 9 5950X used 130 Watts RYZEN 9 7950X used 270 Watts (or there abouts) INTEL 12900 used 285-290 Watts (or there abouts) INTEL 13900 used 315 Watts (or there abouts) Can't point you to the tests but they were on Youtube along with other showing similar results. So the RYZEN 5950X may not be as powerful as the new models but for energy efficiency hard to beat. That's of course if you can find them, they are getting harder to find. I run a RYZEN 9 5900X which has 12 cores + 12 threads which should use even less power as it has less cores than the 5950X. It has 64 GB of RAM and along with a full compliment of other BOINC projects easily runs 9 CPDN work units at a time. Only gets to about 42 GB max depending what I am running at the time (everything not just CPDN) (it may get higher than 42 GB but I have the head room to cover that.) BOINC has not downloaded more than 9 work units at any one time, probably because I am running a lot of other projects at the same time. Conan |

Post: All 9 work units that I had running overnight have completed successfully. Running on an AMD Ryzen 9 5900x, 64GB RAM, all 24 threads used to run BOINC programmes at the same time as the ClimatePrediction models. All took around 17 hours 10 minutes run time. Conan |
