I don't want to through Falkon back in the mix, but Falkon does have an
emulator as well, that can probably do the simulation of multiple
clusters as you said you wanted. This is assuming Coasters will run
over Falkon, and you need significant effort to implement it in Coaster
or a fake provider.<br>

There would be an addition that I would like to make there. In a sense,
the simulator I sent last week was part of an effort to test coasters
without using any remote resources, so that specifically problems with
the allocation algorithm can be isolated. In addition to that I'm
contemplating the idea of having a fake provider that can quickly
simulate one or more large clusters. I'm not sure how doable that is,
and how many useful results that can provide for real life applications,
but if done I think it would provide timely feedback on a number of
components in the coaster code.
