Abstract
In this paper we describe the hardware and application-inherent challenges that future exascale systems pose to high-performance computing (HPC) and propose a system architecture that addresses them. This architecture is based on proven building blocks and few principles: (1) a fast light-weight kernel that is supported by a virtualized Linux for tasks that are not performance critical, (2) decentralized load and health management using fault-tolerant gossip-based information dissemination, (3) a maximally-parallel checkpoint store for cheap checkpoint/restart in the presence of frequent component failures, and (4) a runtime that enables applications to interact with the underlying system platform through new interfaces. The paper discusses the vision behind FFMK and the current state of a prototype implementation of the system, which is based on a microkernel and an adapted MPI runtime.
