Hi all
It seems that when the computer is turned off, when it is next turned on, the task progress is reset to 0 as is the cpu time. Is this right? It seems bizarre to me. Since the screensaver has 1GB of disk space to work with I thought it would save its current progress? Does this mean that there is no value in having this screensaver unless your computer is on 24/7? Or am i overlooking something? Any ideas? |

There is a checkpoint file that is updated each time the Per Cent Completed is incremented by 1%. The Rosetta program should restart from that checkpoint. On the other hand, the question arises if your shut down process ran the Exit routine for the grid Agent. There is a thread in which one member says that using Task Manager to kill the process causes the Agent to send back the partial results when it restarts and request a new Work Unit. I have personally checked the first point by right-clicking on the minimized Grid Icon, running Exit, and then rebooting. My Agent starts with the same Per Cent Completed.

hmmm,
I am concerned that the shutdown routine might not be running as this means that if I ever forget to manually shut it down then the work seems to be lost, well according to the cpu time and task progress. Has anybody else experienced this, or do people generally find that upon restarting, the progress is remembered? Id like to know if this is widespread or not |

I have personally checked the first point by right-clicking on the minimized Grid Icon, running Exit, and then rebooting. My Agent starts with the same Per Cent Completed. There's some wrong information here. Let's clear this up. Rosetta checkpoints at the end of each computed structure. This is indicated by an increment in the the total progress. It's best seen on the graphics screen since we increment in fractions of a percent while the main screen simply shows whole percent. Shutting the computer down shouldn't make the task reset. It'll restart at its last checkpoint. However, if you just hit the power button, there is the possibility of a corrupt checkpoint file. If the Agent detects a corrupt checkpoint (or other files), it will restart from the beginning. Finally, killing Rosetta via the Task Manager will cause the Agent to report an error. It'll immediately send an error back to the server and you'll download a new workunit. However, you'll get no credit for the computation time if the Agent reports an error.

However, if you just hit the power button, there is the possibility of a corrupt checkpoint file So I think you are saying... If I shut down normally by going to the start menu and clicking turn off computer....then I shouldnt lose the task progress. If I have understood correctly then something is wrong as the progress always goes back to 0 on my restarts. I found one other post on this in the feedback section so I know its not just me, but I would like to know is, is this a common bug affecting many people? or is there something wrong with the way my computer is shutting down. Dont get me wrong, I heard what you said about checkpoints, its just that, it doesnt seem to be working for me. |

Hello grahamutton I couldn't find any Post just like yours!
----------------------------------------I found one other post on this in the feedback section so I know its not just me -grahamutton Can you post a {QUOTE} so we can read it too? ???  Robert |

I never shut down the program because it is running as a service. Since the computer is just running a few hours during the day and it creates points the calculation does not reset.
Is something wrong with your installation? |

If I have understood correctly then something is wrong as the progress always goes back to 0 on my restarts. What was the progress before you shut down? Also remember that depending on your computer speed and the load on the CPU, Rosetta may take a minute or more to initialize itself and restore its state from the checkpoint file. Until it does this, it will report 0% on the graphics screen.

How much free space to you have on the hard drive you installed it on? Did you modify your profile? If so, how much did you set the storage amount to? It should be at least 50MB.

I am expereincing something similiar to this problem of resetting. The computer I am running is on 24/7 and Rosetta will get anywhere from 1 to 8 or 9 percent through then reset itself back to zero and start all over again. It will not update the points or cpu time on the agent.
I started running WCG around Nov. 17 and have just 117 points with 4 hours cpu time showing on the agent. I have also witnessed the resetting of the workunit for no apparent reason on a number of occasions. I have downloaded the new agent and unloaded the old agent. I have killed processes so I can get new or bug proff workunits. I have read the majority of the threads in both member to member and feedbact etc. The computer is a : Athlon 2500+ Barton core running at a constant 107 degrees 512 meg of ram 150 gig hard drive with 5 gb allocated to WCG Windows XP Home edition with daily updates turned on It connects to the internet via a cable modem so it is always connected. The computer is only used for DC projects so was set to run Rosetta all the time in the preferences. |

Running and running and not getting points. This condition is discussed on the page for Points System
---------------------------------------- at http://www.worldcommunitygrid.org/join_now/points_system.htmlYes, it really should be moved to the Troubleshooting section. [Edit 1 times, last edit by Former Member at Dec 10, 2004 9:47:02 AM] |
