Erroneous validations or incorrect CPU time? Part 2

Posted 28 Mar 2017 by kashi Post: Thank you for your prompt reply. I was more concerned with very short reported runtimes rather than long runtimes. Having thought about it a bit more the tasks showing very low runtimes all have multiple instances of "Can't set up shared mem: -1. Will run in standalone mode." in Stderr output. Which must mean they have been stopped and restarted a number of times. Thanks again for reassuring me that all results are valid. |

Posted 27 Mar 2017 by kashi Post: I have completed 44 tasks so far. 41 have validated. Computer I'm using hasn't processed any Universe@Home tasks before so I checked the wingmen on all those validated tasks to see if it was performing OK. I discovered something about those wingmen computers that seems strange to me: All are Anonymous Computers. All have highly variable Runtime, sometimes very low. All have no CPU time listed. All are running the same version of Linux: Linux 3.2.0-56-virtual. All use BOINC version 7.5.0. All have the following in Stderr output "Can't set up shared mem: -1. Will run in standalone mode.", sometimes repeated multiple times. Something doesn't seem right here. Similar thing was mentioned in a forum post last October but there was no answer given then. If anyone could explain this I would appreciate it. Seems suspicious to me and I prefer using computer resources and electricity on projects I have confidence in. Thank you. |
