The code in this file drives the F90 VM SendRecv tests. The VM ! Sendrecv 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 character(len=8) :: strvalue ! local variables integer:: i, rc type(ESMF_VM):: vm integer:: localPet, petCount integer:: count, src, dst integer, allocatable:: localData(:),soln(:) real(ESMF_KIND_R8), allocatable:: r8_localData(:),r8_soln(:) real(ESMF_KIND_R4), allocatable:: r4_localData(:),r4_soln(:) type(ESMF_logical), allocatable:: local_logical(:),logical_soln(:) integer, allocatable:: i_recvData(:) real(ESMF_KIND_R8), allocatable:: r8_recvData(:) real(ESMF_KIND_R4), allocatable:: r4_recvData(:) type(ESMF_logical), allocatable:: recv_logical(:) integer :: isum real(ESMF_KIND_R8) :: R8Sum real(ESMF_KIND_R4) :: R4Sum !------------------------------------------------------------------------------ ! 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. !------------------------------------------------------------------------------ call ESMF_TestStart(ESMF_SRCLINE, rc=rc) if (rc /= ESMF_SUCCESS) call ESMF_Finalize(endflag=ESMF_END_ABORT) !

The correct operation of this unit test in uni-process mode depends on ! sufficient internal buffering inside ESMF_VMSendRecv!
