Posted 14 Jan 2017 by Luigi R. Post: As far as I can tell your machine is 8 cores with 8GB of RAM. From the memory perspective 2 Theory tasks are equivalent to 1 CMS task. When starting to run multiple VM tasks on a machine, start small and experiment by slowly increasing what you are running. Always start with a Theory task. If that works then it suggests there are no fundamental issues. Then try 1 CMS before trying 1 Theory and 1 CMS together. It has been mentioned by others that VM starts should be staged. I think there are no issues on this machine. There are moments while 8 VMs are correctly running. My 24GB of ram are enough for 8 CMS tasks as well. Today I'm experiencing many errors: 206 (0x000000CE) EXIT_INIT_FAILURE. https://lhcathome.cern.ch/lhcathome/result.php?resultid=112071733 [ERROR] Condor exited after 686s without running a job. Sorry if I sound repetitive, but I see a bandwidth problem. My host downloaded >2GB in 1.5 hours. I will try to disable CMS tasks and run only 4 Theory tasks to see if things improve. Multicore VMs would be good. |

Posted 13 Jan 2017 by Luigi R. Post: I tried to suspend (without leaving in memory) and resume it, but the same error occurred after the VM completed startup. Then I aborted it. The other tasks are 'gracefully' running. Now I have 8/8 VMs running. https://lhcathome.cern.ch/lhcathome/result.php?resultid=111877625 |

Sixtrack Application :
Getting NO sixtrack WUs even tho my prefs ARE to accept them & test WUs AND serv status keeps saying there are THOUSANDS of Sixtrack WUs to send??
(Message 28478)
Posted 13 Jan 2017 by Luigi R. Post: Hello Life ... oPEA, according to me this is a common problem from Sixtrack project. Hundreds of available tasks are not much to feed all LHC hosts (yours too). Server status is not reliable as much as you think because what you see is an hourly update. That handful of tasks is sent in a couple of minutes. So one believes there are a lot of tasks, but the most of time there are 0 tasks ready to send. I've experienced a strange behaviour some time ago. If you set 10/10 days of additional work and your host gets a couple of hundreds of tasks, then it will go on getting new work because it will be requesting new task every time it will contact server to report finished ones. So the probability of getting new work is good. |

Posted 13 Jan 2017 by Luigi R. Post: Now I have 5 VMs running and 3 idling (2 CMS and 1 Theory). Edit: After 20 minutes 2-3 VMs running. Maybe should I try to limit VMs number to see if I can get 1-2-3-etc... VMs running all the time? Edit2: After another 5 minutes 4 VMs running. |

Posted 13 Jan 2017 by Luigi R. Post: 1MB per job doesn't seem too much. So I don't understand why I have 1 VM running e 7 VMs idling today, 0 running yesterday and 8 running two days ago. stderr.txt idling today

Posted 13 Jan 2017 by Luigi R. Post: Hello, I would like to know the size of 1 job. When I run many VMs (Theory and CMS), I often experience a long-lasting idle. I guess that many concurrent downloads get stuck or maybe job size is too large for my ADSL (~600kb/s). |

Merge Credits from vLHC
(Message 28332)
Posted 4 Jan 2017 by Luigi R. Post: Credit is assigned per application and the breakdown per application can be seen in the project statistics page. Oh, that's what I was looking for. Total credit will also be provided for the project and this will be used by the BOINC stats sites. As it is difficult to compare credit between different projects or applications, such compressions should be avoided or at least viewed with this understanding in mind. I agree. |

Merge Credits from vLHC
(Message 28319)
Posted 3 Jan 2017 by Luigi R. Post: I could argue the same about Sixtrack credits because it was very difficult get tasks in the past. Now someone can get a lot of credits while running VMs and easily overtake great Sixtrack contributors... but I will not do it. I think it is ok to merge all the LHC credits. Maybe you could keep separated credit counts for every application within LHCatHome, but I prefer merged ones on my BOINC statistics. |

Sixtrack (notag/sse2/pni/sse3)
(Message 27823)
Posted 16 Oct 2016 by Luigi R. Post: Hello, I think there is something wrong with server rating process. I'm an i7-4770k owner and I have more than one BOINC client on the same host. The server thinks one of those clients is faster to run (no tag) workunits, guessing cause of short tasks. Totally wrong. Usually I get sse2 tasks. I don't know why I don't get sse3 workunits, but I will try to crunch them through anonymous platform. |

Host messing up tons of results
(Message 27375)
Posted 12 Apr 2015 by Luigi R. Post: 32 tasks is the limit for my host. 32 tasks enduring ~80s (like this) would terminate in 320s. A great number reduces the probability of getting only flash-tasks. Is there a method to know how much time will a task (before running) get? Another reason is also because I've often seen there are not many available tasks. Although I do a little "bunker", I'm finishing work before deadline (except that time). P.S. the other machine (ID: 10356455) errors is cause of win8 failure after update, so no chance to cancel them. ;) [/OT] |

Posted 11 Apr 2015 by Luigi R. Post: About cancelled WUs... Because I have often got network issues with my repeater and "flash"-tasks (that terminate in few seconds) could leave my machine without work. I edited my ncpus from cc_config to get about ~150 WUs and to ensure workload for an entire week, but I got too many ~8h tasks that weren't finishing on time. |

Posted 28 Mar 2015 by Luigi R. Post: Same problem cause of that host. I've got inconclusive validation for 2 or 3 ~8h tasks, that means 1 core-day wasted. A bit frustrating. Thank you for your support. |
