I am sure there are many people who think it is not worth running WCG because their computer is only active a small amount of time each day.
What is the minimum number of active hours per day that we should regard as viable to run WCG? (Assuming a reasonably modern consumer PC running Windows/XP) Thanks Martin |

What is the minimum run time per day that is viable for WCG? It depends on the checkpointing in each project. Some with only a few checkpoints can have problems if the computer is only on 1 hour each day. The workunit doesn't reach the first checkpoint. When the computer is restarted, the workunit starts over. Progress=0. Watch your percentage completion closely when you restart your computer the next day, if you must. If you turn it off at 20% and it is 0% the next day, you get the idea. You start over. If it's around 18-19% using that example, you should be in good shape. If one application has a problem, try one of the others before giving up completely. There are several kinds to try here. The overall mygrid project list is used for BOINC. The project list in the device manager is used for UD.EXE. (My projects has a link to it.) Some running BOINC all day and switching projects to other applications (non WCG) can run up against the same problem. Extending the time to 3-4 hours per project solves most problems. There's another wrinkle. The due date is 7 days away. You must crunch enough each day to complete it in that time. No more than 5-6 days is recommended, in case there is a power failure, lightning, or something. Build in a bit of padding. There may or may not be some grace time, but I would not guarantee any, since it is another techie variable. 20% per day as a minimum goal is a rule of thumb to finish in 5 days if you are crunching one workunit. Many of just leave our computers on, and run all day and all night for the cause. Some of us even have special crunching computers in a crunching farm, that do nothing else.

Doing our bit to ruin the planet for future generations, of course. But what I am after is something to offer people like my neighbours. They are a 65 year old retired couple, both very active in the church (he is a lay preacher) and with relatives working in Africa. They use their laptop for email, for word processing, for his hobby of astronomy etc. They wouldn't dream of leaving it turned on all the time. Isn't grid computing for the millions of people like them, or only for geeks? Thanks for replying. Martin |

Hi Martin,
----------------------------------------In that frame, it's recommended they should run the UD(WCG) agent and only select Genome Comparison and Help Cure Muscle Dystrophy. Both very light and short with regular check-pointing. GC has wide application. Human Proteome Folding 2 will be running for a longer period, but is slightly more hardware demanding with wider check-pointing, but if it runs uninterrupted for a few hours a day, they'd be able to finish the work units also because the UD agent has a 3 week deadline (because is does not have the quorum 3 requirement, which is handled behind the scenes). 6 more projects are planned for 2007, so keep an eye out for them on anything new. cheers and thanks for spreading the word.

Many of just leave our computers on, and run all day and all night for the cause. Some of us even have special crunching computers in a crunching farm, that do nothing else. Doing our bit to ruin the planet for future generations, of course. Texas has passed California as the #1 source of windpower in the U.S. Austin Texas is already very high on the list of windpower utility customers. Many of those have computers. Where would be be if we turned off the grid and just let these diseases run their course....black death? purple death? white death? green death? red death? My computers are doing something directly to find cures as soon as possible. If I send money to a letter from a charity instead of buying a crunching computer, I just get more letters. The letters go to the landfill. We will need more landfills. They use their laptop for email, for word processing, for his hobby of astronomy etc. Sorry, you are only allowed to look at the stars one hour per night. Go back to bed.They wouldn't dream of leaving it turned on all the time. This grid will take any small bit of computing it is given, as long as a workunit can be finished in a week.

Watch your percentage completion closely when you restart your computer the next day, it's recommended they should run the UD(WCG) agent and only select Genome Comparison and Help Cure Muscle Dystrophy. I understood that there isn't any way of measuring percentage completion with the UD agent. If I'm wrong, could you remind me how to do it? If not, could you suggest other ways of measuring progress with the UD agent? Thanks again to both of you |

On the UD overall summary screen, there is a percentage of completion for the workunit. (I am running BOINC at the moment and do not have the exact display for the UD version. Somebody else might paste a screen here.) If you bring up the graphics, there is usually a more detailed percentage to 0.1 precision and a bar. The particular display depends on the project.

On the UD overall summary screen, there is a percentage of completion for the workunit. Many thanks. I have set up a new user on my wife's laptop with GC and Muscular Dystrophy projects. I'll start at 5 hours per day (which is the absolute maximum I could envisage) and work downwards until I find the viable minimum. I'll report back in a few weeks. |

Please see this 'Start Here' post on how to identify 'check pointing' - the saving of the computation models in-progress -.

With the UD agent, is there any record of WUs that failed because they missed the three week deadline? My Statistics History shows me progress of completed WUs but I'm unsure if it will tell me of failures.
Thanks...looking good to use GC for very limited run time per day...can't tell with HCMD as I haven't had any WUs yet! Martin |
