I've just installed 1.8.2, something is still wrong with
HINDEXED_BLOCK datatypes.
Please note the example below, it should print "ni=2" but I'm getting "ni=7".
$ cat type_hindexed_block.c
#include <stdio.h>
#include <mpi.h>
int main(int argc, char *argv[])
{
MPI_Datatype datatype;
MPI_Aint disps[] = {0,2,4,6,8};
int ni,na,nd,combiner;
MPI_Init(&argc, &argv);
MPI_Type_create_hindexed_block(5, 2, disps, MPI_BYTE, &datatype);
MPI_Type_get_envelope(datatype, &ni, &na, &nd, &combiner);
printf("ni=%d na=%d nd=%d combiner=%d\n", ni, na, nd, combiner);
MPI_Type_free(&datatype);
MPI_Finalize();
return 0;
}
$ mpicc type_hindexed_block.c
$ ./a.out
ni=7 na=5 nd=1 combiner=18
