Daniel, Many papers have been published about the performance modeling of different collective communications algorithms (and fortunately these models are implementation independent). I can pinpoint you to our research in collective modeling which is the underlying infrastructure behind the decision function in the tuned collective module in Open MPI ( http://link.springer.com/article/10.1007/s10586-007-0012-0). However, Google Scholar can help with discovering other interesting approaches.
