Andy, John, Fritz How about we meet on Tuesday afternoon, say at 2pm for a couple of hours to brainstorm about shared scans? I would like to put aside for some time "what we already have" sentiments, go over all our requirements/needs and try to come up with a solid design that addresses all our needs. We can then see how the existing code and APIs and thinking fit into that design (ScanScheduler / BlendScheduler / shrscan/Director etc) Something to think about ... maybe it'd make sense to look at shared scans from the perspective of worker scheduler (which tasks gets run when) and czar scheduler (orchestrating multiple concurrent shared scans etc). Perhaps one of you can work on worker side and the other or czar side? Further, perhaps we could draw a line between worker scheduler and resource manager on a worker (locking files in memory etc). Anyway, let's talk next week!
