Re: UD Monitor 4.35 beta 3, now with WCG support

Unless you happen to get relatively short work units, using this to save up and work on several work units can cause wasted work, if your final results arrive back at the server much later than normally expected.

There is a dead-line for each workunit, which consists of CPU time and wall clock time. You just need to ensure that no WU sits in the cache for longer than the current wall clock dead-line time (3 weeks).

I know that UDMon is not a supported or even recommended solution but I agree with Roman (BTW thanks for a great bit of software).

I have used UDMon for the UD Cancer project, Folding@Home and also here at WCG and have never seen a problem as long as you only download a sensible number of WUs.

If your machine takes a week to crunch a relatively small WU, then you should not download more than 2. If you have a machine that can crunch 5 a day, then you could probably download about 8.

You have three weeks wall time between downloading the WU and finishing it. Within this time, you have a maximum of two weeks crunching time so you have to remember this.

I would like to see an answer regarding what happens with aborted WUs. I know that if you abort it (by killing the process) or if it is aborted automatically due to a timeout (wall or crunching), you still get given some points.

What I don't know is if these WUs are then reallocated to someone else to crunch due to the fact that they are not finished.
