is there an advantage to have one WU work for longer time?
or better yet.. whats better... longer WU or shorter WU?

smaller work units are always better.

when they crash, you lose less crunching time.

But then more computers is needed to get same amount of "decoys".

with shorter task run-times a computer will produce fewer decoys per task but will run more tasks so you'll end up with the same work produced either way.

As Angus says, shorter tasks reduce the impact of failures, but longer tasks reduce the upload/download overhead to the user and the project.

More tasks,but there will be very interesting overhead and remeber that we sometimes receive task with huge time to finish per edcoy and then client is not only confused.

And so far the only problem I had was huge memory requirment with BOINC cycling through WUs killing any free memory...
And I participate at RALPH with no error...(24h setting!)

Just my POV. :-)

i just put it on 2 hours. :)

Small warning:Some decoys wil take more than two hours so do not be suprised,that it will not honour exactly setting in such case.(So far however this long tasks are rare...for now :-) )

what are decoys??

Hopefully I say it simply:Each decoy is one successfull attempt at folding given protein.
But not so sure about this description,but somewhere here should be full explanation.Search function is your friend.I recommend trying science subforum.(Unfortuantely I have not enough time to do search myself. :-( )

...and the word decoys and the word models are basically used interchangebly. You don't know until other scientific methods are used to confirm the resulting structure if your model was a decoy, or "the solution".

I just had a WU, 1gidA_BOINC_SEQSEP_TITRATION_500KCYCLES_RNA_ABINITIO_RNA_CONTACT_RNA_LONG_RANGE_CONTACT_RNA_SASA-1gidA-_3003_9153, take over 8 hours to do a single decoy on an Athlon 1800+. As I'm currently using a 16 hour setting, the program decided not to try for a second decoy.
