Abstract
AbstractHigh Performance Computing (HPC) provides support to run advanced application programs efficiently. Message Passing Interface (MPI) is a de-facto standard to provide HPC environment in clusters connected over fast interconnect and gigabit LAN. MPI standard itself is architecture neutral and programming language independent. C++ is widely accepted choice for implementing MPI specifications like MPICH and LAM/MPI. Apart from C++ other efforts are also carried out to implement MPI specifications using programming languages such as Java, Python and C#. Moreover MPI implementations for different network layouts such as Grid and peer-to-peer exist as well. With these many implementations providing a wide range of functionalities, programmers and users find it difficult to choose the best option to address a specific problem. This paper provides an in-depth survey of available MPI implementations in different languages and for variety of network layouts. Several assessment parameters are identified to analyze the MPI implementations along with their strengths and weaknesses.KeywordsJavaC/C++PythonC#Gridpeer-to-peermessage passingMPI
