1) Message boards : Number crunching : Erroneous validations or incorrect CPU time? Part 2 (Message 2076)

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.

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.
