Foil 91 MPI Java + Message Passing

From Java Grande: Role of Java in Large Scale Computations NPACI Summer Institute on Parallel Computing -- August 21 98. by Geoffrey C. Fox


1 Naturally one can implement an MPI linkage for Java and this has been implemented by NPAC (mpiJava) Mississippi State and Westminister College (London)
2 There is no formal definition of Java binding to MPI ad there are some areas of uncertainity
3 Westminister version automatically links C version of MPI to Java Native Interface (JNI)
4 NPAC version "optimizes" Java link based on C++ MPI standard noting Java does not support "memory sequence" but with serialization could allow transfer of objects http://www.npac.syr.edu/projects/pcrc/mpiJava
5 MSU version goes one step further with a version even more tuned to Java
