This is slightly off topic, but people do this for numeric software
libraries. HW platforms for supercomputers vary widely in their
structure. This is true even for similar platforms. Configuration
options on different instances of one kind of machine can cause the
algebraic software to perform wildly differently. You'll still get
the same answer, but one may take a lot longer than the other. So,
there is a distribution of LAPACK and BLAS which compiles them several
ways, and has an optimizer which compares the results and chooses the
best one. In fact, the optimizer steers the selection of which parameters
to choose. I think it's pretty slick.
This is a very different situation, though, as the libraries in question
are very much a shared resource, and they need to be as fast as possible.
People who do numeric computing are also willing to do more work to get
their answers than you are, whoever you may happen to be.
