Please fix this issue. How could you release software like this!

What issue?......That is what it's designed for.
It doesn't prohibit one from everyday computer use. |

Well... it's designed to do that, and it's using all of your idle cpu cycles. Nothing to worry about. I think there was also a cpu throttle feature somewhere... could someone dig it up?

Please fix this issue. How could you release software like this! This is normal. It is all explained here along with how to reduce this percentage if you have an unusual situation that requires this. |

Ahhh. Thank you. Much better. Sorry for my earlier slur, but perhaps you should present this option up front.
Now, will the screen saver run at 100%? That would be perfect! |

Assuming that there is nothing else running in the background which has a higher priority, the screensaver will use all available cycles. However, the screensaver uses some of those cycles to draw the graphics on the screen, so you don't actually get all of the available processing power allocated to real crunching.
You can always configure your screen saver to be blank and run the agent minimised. This way, you can still have the "security" of a screensaver but give as much spare cycles to the crunching. |

Not so fast!
I've noticed that upon return from hibernation or suspend (in WinXP SP2), that sometimes Rosetta and it's parents (UDXXX.exe and UD.exe) will sometimes take on 100% at NORMAL priority (or so it seems). My machine is pretty much unusable until I terminate the Rosetta (and then the subsequent UDxxx.exe and UD.exe processes that get 'restarted'). If I then startup Rosetta, it's fine (goes back to using 100% at low priority). Also, has anyone noticed that it's near impossible to delete Rosetta from your startup list? (if you put your mouse over the icon and select it, you get a trap-d (unrecoverable program error)). Same goes for trying to delete the icon. |

I have never seen a problem with hibernation or suspend on my laptop.
We have to be clear about what processes are run at what priority. Ud.exe runs at normal priority. It spawns a sub process called ud_xxxxx.exe (where xxxxx is a set of digits). This has an idle priority. This in turn then spawns WCGrid_Rosetta.exe or WCGrid_AutoDock.exe which also has an idle priority. There has been some cases of some issues with certain display cards. Can you let us know what display card you have ? Do you have the latest drivers for it ? |

I have this problem where after return from suspend the world community grid executables have hijacked the processor, and the system becomes unusable until you kill them manually.
I'm running an IBM Thinkpad x31 with an ATI Mobility Radeon display built in. I now know to kill the processes manually, but its not an acceptable behavior for the long term. Anything at all that I can do to help out feel free to ping me at: bishel at us dot ibm dot com geoff |

Hello bishel,
There is something strange about 'suspend' on your machine. But since I cannot think of a solution, I will concentrate on what I do know. First, you should be able to do a controlled shutdown by right-clicking on the WCG icon in the SysTray and selecting Exit. If things are going wrong there, please explain. It turns out that there is a bug in the OS code for SysTray with a fix that Lewis Carroll (our mad logician Community Admin) loves to explain. If for some reason that does not work, then start by killing UD.exe and work down. Never start by killing WCGrid_Rosetta.exe, because UD considers that proof that something corrupted the application program and downloads a new copy, plus work unit. So kill Rosetta last. How does Rosetta get suspended, on your machine? mycrofth |
