Hi all, I have just installed the latest BOINC version for 64-bit linux, boinc_6.10.17_x86_64-pc-linux-gnu.sh My system is: OS: Ubuntu 9.10 64-bit CPU: Xeon W3520 3.80 ghz GPU: NVIDIA GTX 275 Problems: I can't seem to get BOINC to actually do anything! In the Simple view, I have tried to attach to World Community Grid and I just see: "Waiting to contact project servers" In the manager, it's an endless loop of cpu_sched_debug: [cpu_sched_debug] enforce_schedule: end [cpu_sched_debug] enforce_schedule(): start [cpu_sched_debug] finished preempt loop, ncpus_used 0.000000 [cpu_sched_debug] using 0.000000 out of 8 CPUs etc etc etc. Also: I can successfully run CPU benchmarks and I get 3476 Whetstone and 8040 Dhrystone per CPU. In Windows 7 64-bit, I get 3560 Whetstone and 12050 Dhrystone per CPU. Just another thing that's confusing me, the lower Dhrystone in Ubuntu. But more importantly than that! How do I get BOINC to start using my CPU cores? Are there (probably multiple) things I need to do in Ubuntu to get everything going? Or do I need to install 8.04 or something instead of 9.10 to use BOINC? I will certainly post more info if needed. Thank you so much, Hoping to help science soon! |

Since BOINC doesn't come with the core client configuration (cc_config.xml) file, you must have made one by yourself. The cpu_sched_debug flag that you see running is one of the flag options to set, it normally doesn't run by itself. So can you check in the same file whether you've set <ncpus>0</ncpus>? If so, either remove this line, or change it to <ncpus>-1</ncpus> to disable it. That's minus one. Save the file and restart BOINC. |

I attach to WCG using the same login that works in Windows, so I know it's not a login issue. It must be BOINC settings or some networking related thing in Ubuntu...

Hi all, Yes, I "fixed" my problem by attaching to different projects. I already have a few servers running WCG 24/7 so it's fine if my Linux Xeon crunches Rosetta, Aqua etc. (I know this isn't really a fix) I guess my last question is the difference in integer MIPS per cpu between Windows 7 64-bit and Ubuntu 9.10 64-bit. BOINC gives me 12000 MIPS per cpu in Windows 7 and a little over 8000 per cpu in Ubuntu (floating point MIPS are not changed much). I know it's not a big deal, but could this be a Ubuntu configuration thing? htop tells me that 100% of my CPUs are being used... so I don't know why the difference? (or should I not worry whatsoever) |
