i am running the client on a computer with susu 9.1. the computer swap memory is: SwapTotal: 136544 kB SwapFree: 136528 kB however, when i check my account/computers it says that i have swap space: 0 i re-ran the benchmarks, but it didn't fix it. the client is running very slowly (showed only 15 minutes of cpu time after running for 3 hours and 15 minutes on the computer with nothing else running). what do i need to do to fix this? thanks, -eric |

I don't think swap space is currently being checked. All of my hosts show swap size of 0 also - though they all have it. However, something is most definately taking your cpu time. Run the command top in a terminal and it will show you what is getting what percentage of your cpu. The output will be something like this: [darren@platinum darren]$ top top - 19:23:03 up 4 days, 10:48, 3 users, load average: 1.17, 1.06, 1.03 Tasks: 110 total, 2 running, 108 sleeping, 0 stopped, 0 zombie Cpu(s): 2.0% us, 0.7% sy, 97.0% ni, 0.0% id, 0.0% wa, 0.3% hi, 0.0% si Mem: 904988k total, 873832k used, 31156k free, 58952k buffers Swap: 811240k total, 9028k used, 802212k free, 506192k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 28556 darren 39 19 17820 14m 2696 R 97.5 1.7 115:32.39 setiathome_3.08 2752 root 15 0 185m 53m 140m S 1.7 6.1 55:43.14 X 28787 darren 15 0 20680 12m 16m S 0.3 1.4 0:00.71 gnome-terminal 28822 darren 16 0 2172 1060 1964 R 0.3 0.1 0:00.04 top 1 root 16 0 1580 516 1424 S 0.0 0.1 0:03.12 init 2 root 34 19 0 0 0 S 0.0 0.0 0:00.01 ksoftirqd/0 3 root 5 -10 0 0 0 S 0.0 0.0 0:00.77 events/0 --------------------- As you see here, seti at the moment is getting 97.5% of my cpu. To stop it after you see what's running, just press ctrl-c. Depending upon what else is running and taking the cpu, you may or may not be able to do much about it. |

I have 446504 KB of swap space on my Linux box, but BOINC does non see it.I have 224.88 MB of RAM but BOINC sees 218.84. All other parameters are OK. |

apparently linux reporting from boinc is a bit borked, I also noticed the lack of swap reporting from the linux client, as well, the time here is currently -6 UTC, and is set correctly on my linux machine....under my computers you'll see UTI -6 on both the windows XP machines, while the linux box is reporting -5...an obvious problem translating daylight savings transitions from the linux client... |
