PVM (the current version 3.4) as well as many current MPI implementations force application programmers to use active polling (also known as busy waiting) in larger parallel programs. This serious problem is related to thread-unsafety of these communication libraries. While the MPI specification is very careful in this respect, the implementations are not. We present a new mechanism of interruptable blocking receive which makes PVM and MPI quasi-thread-safe. This mechanism does not require any modifications to the existing semantics of PVM or MPI (we only extend the interfaces with two new functions) and allows writing multi-threaded programs without active polling. Then we sketch how the interrupt mechanism can be hidden in the implementations of PVM and MPI, making both PVM and MPI completely thread-safe without active polling. Results of our experiments promise a significant speedup for all larger communication-intensive parallel applications.
