Mainly because at it's core, LAM has always been a research project and
given the choice between binary compatibility and new research, we had
to be able to do the research. Binary compatibility is also hard and
time consuming.
With Open MPI, which is funded by people interested in production
environments, we are trying much harder to guarantee binary
compatibility. It isn't always possible, but we're trying.
