Exclusive prefix sum:
|MPI_MAX||return the maximum|
|MPI_MIN||return the minimum|
|MPI_SUM||return the sum|
|MPI_PROD||return the product|
|MPI_LAND||return the logical and|
|MPI_BAND||return the bitwise and|
|MPI_LOR||return the logical or|
|MPI_BOR||return the bitwise or|
|MPI_LXOR||return the logical exclusive or|
|MPI_BXOR||return the bitwise exclusive or|
|MPI_MINLOC||return the minimum and the location|
|MPI_MAXLOC||return the maximum and the location|
In this case, the constants are used with the MPI_Scan function.
