I have 3 machines running WCG, all on Windows XP.
On 2 (1 XP Home, 1 XP Pro) I notice that sometimes WCG appears to cause the machine to hang. For example, I can't look at "My Recent Documents" - it takes minutes to open the list of documents. Other times the children's games don't want to start. Is anyone else experiencing this? Short of just using WCG as a screensaver anyone got a fix/workaround? thanks Ian |

Ian,
Are you sure it is WCG? Whats your machine config (ram, cpu, disk)? If you get a "hang" try ctrl-alt-del to bring up the windows security menu. Select the task manager button, pick the processes tag and then click twice on the word CPU (you should see a yellow bar under it). The double click sorts the processes in order so if it is WCG you should see it (WCGrid_Rosetta.exe) at the top using 100%ish CPU and either 72MB (ish) or 25MB or RAM (this may be one of Ricks tuned work units). I would expect rosetta to go drop down from 100% if you start something else. Give it a try and see what happens.. sorry if these instructions are a bit "noddy". Paul |

Hi Paul
thanks for the suggestions, all of which I have tried. Memory usage is about 10-11000k for Rosetta. This is on AMD-Athlon 2.16 ghz 512mb memory. 35gb free space on harddrive. The other machine is not such good spec. but is still fine according to the Grid "device information". I regularly run Ad-aware, Spybot S&D and Norton Anti Virus and have a hardware & software firewall!! Killing the "rosetta" process usually seems to resolve the problem, but I must say not always.

Ian,
So when you kick off another process does the CPU utilisation go down? I have a similar config - using norton, adaware and spybot so I dont think any of those interfere. Paul |

Hi Paul thanks for the suggestions, all of which I have tried. Memory usage is about 10-11000k for Rosetta. This is on AMD-Athlon 2.16 ghz 512mb memory. 35gb free space on harddrive. The other machine is not such good spec. but is still fine according to the Grid "device information". I regularly run Ad-aware, Spybot S&D and Norton Anti Virus and have a hardware & software firewall!! Killing the "rosetta" process usually seems to resolve the problem, but I must say not always. Also, the fact that you say it doesn't always resolve the problem indicates something else on your machine is causing the problem. Ian Rosetta runs at the lowest priority on the system, so it shouldn't be interfering with anything. It almost sounds like you are swapping quite a lot, which is what's causing things to take a while to start up. Rosetta should definitley be ustin 1.1GB of RAM. It will either be allocating ~300MB or ~200MB depending on if you have the latest version. For actual memory usage, it should be using either ~75MB or ~25MB. If it's running away on your machine, I'd be very interested, because I've never seen it and no one else has seen this either. Finally, killing Rosetta causes the workunit to abort on your machine and you receive no credit for any work you did, since you didn't send any results back. A couple of questions: * When you notice this problem occurring, how much memory is currently being used? Open up the Task Manager, click on the Performance tab, and tell me the total Commit Charge that it lists. * What size if your paging file set to? - Control Panel -> System - Click on the Advanced tab. - Click the "Settings" button in the Performance section - Click the Advanced tab - At the bottom, tell me what you have for "Total paging file size for all drives"

Thanks for the suggestions.
My PC's have now gone into "demo" mode ... ie if I need to demonstrate a "feature" I no longer can.  Everything seems to be fine now, I can no longer recreate the "problem" I thought I had. So ... I'll keep looking out for such hangs, but I guess it was probably user error ... ! thanks Ian |
