Benchmarking mpiJava with serialization

• Assume in “Grande” applications, critical case is arrays of primitive element.

• Consider N x N arrays:

float [] [] buf = new float [N] [N] ;

MPI.COMM_WORLD.send(buf, 0, N, MPI.OBJECT,

dst, tag) ;

float [] [] buf = new float [N] [] ;

MPI.COMM_WORLD.recv(buf, 0, N, MPI.OBJECT,

src, tag) ;
