Abstract	Coordination languages are an established programming model for distributed computing, but have been largely eclipsed by message passing (MPI) in scientific computing. In contrast to MPI, parallel workers never directly communicate, instead "coordinating" indirectly via key-value store puts and gets. Coordination often focuses on program expressiveness, making parallel codes easier to implement. However, coordination also benefits resilience since the key-value store acts as a virtualization layer. Coordination languages (notably Linda) were therefore leading candidates for fault-tolerance in the early '90s. We present the FOX tuple space framework, an extension of Linda ideas focused primarily on transitioning MPI codes to coordination programming. We demonstrate the notion of "MPI Perturbation Theory," showing how MPI codes can be naturally generalized to the tuple-space framework. We also consider details of high-performance interconnects, showing how intelligent use of RDMA hardware allows virtualization with minimal added latency. The framework is shown to be resilient to degradation of individual nodes, automatically rebalancing for minimal performance loss. Future fault-tolerant extensions are discussed.
