[mpich-discuss] Can i use MPI_REDUCE(with MPI_MIN) to get a "min array"?

[维洛逐风]

HI.


Say,I have 10 process，each one has a array called gbest, I want to get the min array(with a compare operation I want to define).
Is there a way to use MPI_REDUCE to do this?As I know, MPI_MIN specifies datatypes(without arrays).
