I go to bed at noon and get up at midnight :-)Look what motherboard and CPU you have and decide what the max size and speed sticks they will take are. Let me know the CPU and MB models if you want me to find out. They are all Vbox, it's just not shown on the Boinctasks history. I've never seen anything multicore that doesn't have (vbox64) at the end of the application name.This is the only types I've ever received:The 6C implies 6 cores per task and says nothing about whether Virtualbox is used. |

(vbox64) in the "Version" col indicates an app that requires VirtualBox 64-bit. (vbox64_mt) in the "Version" col indicates an app that requires VirtualBox 64-bit and is able to run multicore VMs. 64-bit vbox apps don't run on a computer that has 32-bit vbox installed. |

I saw multithreaded yafu, primegrid LLR and amicable numbers. |

Sid, again aagb Greg: not sure if this is the right msg to refer back to, but returning home after 3 days away, I found 3 tasks that had stalled One task was aagb as discussed before, but the other two were aaam. After 3 days of 24hr running, and having 10 tasks run at a time, this is comparatively good and 7 out of 10 of my current tasks are aagb all running fine, indicating problem tasks aren't quite the way we assumed before. Those three and only one other task (after a reboot) errored out in the last 75 hours For what that's worth (possibly nothing) |

For me no more (vbox64) Task from this project. It causes issues with the BOINC Client Software and it is not well programed to run under the BOINC.Client Software. |

Fortunately we can run folding@home if we want multithreaded protein simulation. |

Fortunately we can run folding@home if we want multithreaded protein simulation.Yes, folding at home is doing everything not possible elsewhere, funny that. Not all programmers are created equal. In it's simplest form, of course it's possible, if you want to download a 24 core protein task , the server can send you a batch of 24 things to do, and run them all at the same time. This is in fact how LHC ATLAS works. It you look inside the virtual machine, there are 200 tasks to do. It sets off doing 1 at a time on each core until they've all run out. |

Trying to complete a task remaining from the Formula BOINC sprint. It is a aagb-SAR-AIB-GPN task at 3d 3hr 35min at 99.991% completed with 26 seconds to go. However, it doesn't make fast progress. I am reluctant to abort it as it has tied up my laptop for such a long time. CPU is set to 100 percent. CPU is Intel I7-9750H @ 2.6Ghz, 32GB dual channel RAM. Rosetta reports vbox64 application in use. VB is 6.1.32 r149290 |

Yeah unfortunately there are lots of bad VirtualBox tasks that waste lots of CPU time. I don't know of any way to deal with them other than to abort them unfortunately. |

I have two computers that do 99% of them ok. I have 5 computers that never do them. Perhaps there's an instruction in CPUs required for a small number, but all my machines are either new enough to have it or old enough to break every one of them. |

I feel so good with your topic, Thank you. Please let's spread stories like this again. เว็บผลบอล ผลบอลสด365What are you wearing? |

Only your 3800XT and your i5 have AVX so the other machines will all suffer from the Intel MKL crash. |

Agreed. But why do my i5 and 3900XT virtually never have a faulty task?I don't experience this. I have two computers that do 99% of them ok. I have 5 computers that never do them.

Agreed. But why do my i5 and 3900XT virtually never have a faulty task? Yeah, that I don't know! My 3700X seems to have more issues than my other machines. Maybe because I use it more. Or maybe these tasks are more sensitive to something like memory errors. |

I find AMD doesn't like Virtualbox, it makes it slow down like crazy. But it doesn't affect the program, just the interface.Agreed. But why do my i5 and 3900XT virtually never have a faulty task? Have you checked your memory is perfect? Bad memory is a very nasty thing to have. Use memtest. I always use this on any new or used memory I buy before I put it into use. |

Yeah I've run memtest on all of my machines - so easy from the start menu in Windows these days. No issues detected though. |
