! !PROGRAM: ESMF_VMAllGatherUTest - Unit test for VM AllGather Functions
!
! !DESCRIPTION:
!
! The code in this file drives the F90 VM AllGather tests. The VM
! AllGather function is complex enough to require a separate test file.
! It runs on multiple processors.
!
!-----------------------------------------------------------------------------
! !USES:
use ESMF_TestMod ! test methods
use ESMF
implicit none
!------------------------------------------------------------------------------
! The following line turns the CVS identifier string into a printable variable.
character(*), parameter :: version = &
'$Id$'
!------------------------------------------------------------------------------
! cumulative result: count failures; no failures equals "all pass"
integer :: result = 0
! individual test failure message
character(ESMF_MAXSTR) :: failMsg
character(ESMF_MAXSTR) :: name
! local variables
integer:: rc
type(ESMF_VM):: vm
integer:: localPet, petCount
integer:: nlen, nsize, i
integer, allocatable:: array1(:), array2(:)
real(ESMF_KIND_R8), allocatable:: farray1(:), farray2(:)
real(ESMF_KIND_R4), allocatable:: f4array1(:), f4array2(:)
!------------------------------------------------------------------------------
! The unit tests are divided into Sanity and Exhaustive. The Sanity tests are
! always run. When the environment variable, EXHAUSTIVE, is set to ON then
! the EXHAUSTIVE and sanity tests both run. If the EXHAUSTIVE variable is set
! Special strings (Non-exhaustive and exhaustive) have been
! added to allow a script to count the number and types of unit tests.
