Hello,
I am converting an existing MPI program in C++ to Java using OpenMPI 1.8.4,
At some point I have a allToAllv() code which works fine in C++ but
receives error in Java version:
MPI.COMM_WORLD.allToAllv(data, subpartition_size, subpartition_offset,
MPI.INT,
data2,subpartition_size2,subpartit
e useful to know which java version you are using, as well
> as the configure options used when building open mpi.
