We show how expressions written in a functional programming language can be robustly evaluated on a modular asynchronous spatial computer by compiling them into a distributed virtual machine comprised of reied bytecodes undergoing diusion and communicating via messages containing encapsulated virtual machine states. Because the semantics of the source language are purely functional, multiple instances of each reied bytecode and multiple execution threads can coexist without inconsistency in the same distributed heap.
