Nobody is working on this project. I'm still moderating the listserv but
that's about it.
The original project was a Masters or PhD thesis project, then opensourced
under the "management" of the University of Melbourne's Gridbus group. They
seemed to have lost interest. There were a couple of us making some active
work around 2008 or so, but Matt got hired by Microsoft and as for me, life
got in the way. Not exactly sure what happened to the others. Anything
else in the codebase (e.g., WCF support) has been contributions from users,
but there hasn't been any active mainline development for a very long time.
All the real documentation that I know of hasn't really been touched since
about 2004. As for basic usage, some (most?) of the example projects should
still work.
IIRC, the functionality that you're looking for would be something built
into the "scheduler", but I never took a look at that implementation. All
that's there now -- again, as far as I know -- is a basic FIFO scheduler
with no intelligence of jobs or executor resources. We did some
brainstorming awhile back, but never ended up with any code.

<http://tools.assembla.com/alchemireloaded>Let me take a quick peek at the
code to see if I can at least point you in a slightly better direction.
-- [looking] --
Ok, so it seems to work like this. There's Alchemi.Manager.IScheduler,
Alchemi.Manager.SchedulerFactory, and Alchemi.Manager.DefaultScheduler.
I believe if you implement the following method in IScheduler:
ThreadIdentifier ScheduleNonDedicated(string executorId);
Then you should be able to use that for any more "intelligent" decision
making based upon an Application <-> Executor mapping.
Also I just found MappingScheduler.cs which may provide some/all of what you
need. I didn't really read through the code yet.

Hope that helps some,
