Detailed Description

Reduces a scalar/array on all nodes.

All functions have the same argument list only differing in the type and rank of the second and third arguments. The second and third arguments can be of type integer (i), real (s), double precision (d), complex (c), double complex (z) and logical (l). Their rank can vary from zero (scalars) up to the maximum rank. Both arguments must be of same type and rank.

Example:

  implicit none

  integer, parameter :: dp = kind(1.0d0)

  call mpifx_init()
  call mycomm%init()
  valr(:) = [ (mycomm%rank + 1) * 1.2_dp, &
