MPI_ANY_SOURCE: what is it good for? Semantics of point-to-point operations revisited: matching, message ordering, determinism and nondeterminism, examples. The need for barrier synchronization when using MPI_ANY_SOURCE. Load balancing and the manager-worker pattern. Floating-point nondeterminism. Example: numerical integration: adaptive quadrature.
