HPJAVA: A DATA PARALLEL PROGRAMMING ALTERNATIVE

摘要

TODAY, THERE IS A HEALTHY DIVERSITY OF PROJECTS AIMING TO HARNESS JAVA FOR SCIENTIFIC (OR "GRANDE") COMPUTING. IN FACT, THIS DEPARTMENT LOOKED AT SEVERAL OF THESE APPROACHES IN A RECENT ARTICLE. HERE, WE WILL FOCUS ON A particular project that's ongoing at our Pervasive Technology Lab at Indiana University. The HPJava (high-performance Java) project aims to support scientific and parallel computing in a modern, object-oriented, Internet-friendly environment―the Java platform. HPJava leverages popular high-performance Fortran (HPF) language and library features such as "scientific" multidimensional array syntax and distributed arrays, while at a more language-independent level, it introduces a slightly unusual parallel programming model, somewhere in between the classical HPF and message-passing interface (MPI) extremes. We'll say more about this later. See the "HPJava History" sidebar for some of the language's developmental roots.
