ii The latteMPI project is a pure Java implementation of a subset of the Mes-sage Passing Interface (MPI) Standard. The MPI Standard defines a number of methods that facilitate writing programs using the message-passing model of computing, where processes share data using explicit calls to send and re-ceive functions. Performance of parallel programs running on both latteMPI and a C implementation of the MPI Standard is investigated. The performance of latteMPI is slower than the equivalent C implementation, but some Java-specific advantages are discussed: reduction of setup time and portability of programs
