SUMMARY:OpenMPI+Java as a High Performance Language
DESCRIPTION:Workshop\n\nOpenMPI+Java as a High Performance Language\n\nAda
 ms\n\nThe Message Passing Interface (MPI) is a software platform that can 
 utilize the parallel capabilities of most multi- processors, making it use
 ful for teaching students about parallel and distributed computing (PDC). 
 MPI provides language bindings for Fortran and C/C++, but many university 
 instructors lack expertise in these languages, preventing them from using 
 MPI in their courses. OpenMPI is a free implementation of MPI that also pr
 ovides Java bindings, allowing instructors who know Java but not C/C++ or 
 Fortran to teach PDC. However, Java has a reputation as a “slow” language,
  so some say it is unsuitable for teaching PDC. This paper gives a head-to
 -head comparison of the performance of OpenMPI’s Java and C bindings. Our 
 study shows that by default, Java can be faster than C unless one takes sp
 ecial measures, and it exhibits similar speedup, efficiency, and scalabili
 ty. We conclude that Java is a suitable language for teaching PDC.\n\nSess
