CREATED ISSUE: Change Experiment Plug-in Architecture

tansey — Mon, 09 Jul 2007 18:36:58 GMT

The way that experiments are loaded currently is to use the app.config file to specify a bunch of parameters. This isn't very elegant and should be improved to work similar to the WorkerGUI's architecture.

CREATED ISSUE: Variable Evaluations Per Worker Per Generation

Many distributed environments are composed of heterogeneous systems with varying performance capabilities. It would be nice if we could accommodate this property by allowing workers to specify how many workers they can handle, either directly or by some metric which can be scaled.

CREATED FEATURE: Add Workers During Experiments

The current release takes a list of worker nodes in the configuration file at startup and uses only those nodes for the entire experiment. Since this is a distributed environment, it would be nice if we had the ability to add a new worker mid-way through an experiment.

CREATED ISSUE: Fault Tolerance

Currently, if a worker disconnects before the experiment is finished, it will crash the master. This needs to be handled in a more elegant way by first alerting the Master's GUI that it has lost a worker and then having the master gracefully shift any incomplete work onto the remaining worker nodes.
