Abstract

Java is one of the most widely used computer programming languages, however its use inHigh Performance Computing (HPC) is relatively low. A typical HPC environment consists ofa number of multi-core computing nodes, while a typical application running in such anenvironment will normally contain CPU intensive code that can be executed in parallel.Such an application may require inter-node as well as intra-node communication. MessagePassing Interface (MPI) is a language independent specification of an API to allow suchcommunication. MPJExpress (Baker et al. 2006) and F-MPJ (Taboada et al. 2009) are Java-based implementations of MPI, designed with the efficientperformance of data transfers as a main objective. In this paper we discuss thescalability of one approach of distributing data to compute nodes in HPC and we proposethe design of an alternative data transfer system, building upon MPI.
