Marathon at Rosetta@home — about task duration:
[...] when the watchdog was implemented in Rosetta, the developers and admins decided to expose the target CPU time to contributors as a configuration option, allowing them to deviate from the default if they use their computers in a different manner than the project developers anticipated.
The setting is located at the user page at the Rosetta@home web site, in "
Rosetta@home preferences". You can choose non-default target CPU times anywhere between 2 hours or 36 hours.
[...] While the tasks themselves are affected as described above, the runtime estimation of boinc-client is not influenced by a change of this setting. Boinc-client merely recalls how long Rosetta tasks used to take in the past, and assumes that new tasks will take just as long. The client will require a very long period of observing further tasks in order to gradually adapt its runtime estimation.
Consequently, not only does boincmgr show estimations which may be way off, but boinc-client is also highly confused when it is meant to fetch work for a buffer of
n days duration. It will fetch far too few tasks, or far too many tasks, depending on whether you decreased or increased the target CPU time, and by how much you changed it.
