Kaffemik - A distributed JVM on a single address space architecture

New memory mapped network interfaces offers both low latency and high bandwith communications. This has implications on the design and implementation of distributed operating systems, especially with respect to global management of resources. This paper presents Kaffemik, a scalable distributed Java Virtual Machine, providing the programmer with a single machine abstraction. Kaffemik is built on a distributed single address space system, which exploits the hardware support for DSM offered by the Scalable Coherent Interface (SCI). The purpose of the Kaffemik project is to explore global management of resources in a cluster of workstations. In this paper we focus on the design and implementation of Kaffemik and we present preliminary performance measurements from the current prototype. Keywords—single address space architectures, distributed JVM, cluster computing
