! $Id$ ! ! System test FieldRedistBlk2Blk !------------------------------------------------------------------------- !ESMF_MULTI_PROC_SYSTEM_TEST String used by test script to count system tests. !========================================================================= !BOP ! ! !DESCRIPTION: ! System test FieldRedistBlk2Blk. ! ! This system test checks the functionality of the grid distribution ! routines by redistributing data from one Field distributed in the normal ! block structure to another Field that has been distributed regularly ! and then back again. The original data should exactly match the final ! data, which serves as the test for SUCCESS. This program creates two ! identical Grids with different distributions, one with the normal block ! structure and the other with a different block distribution. The first ! Grid has two Fields created from it, the first as the source for the test ! and the second for the final results. The second Grid has a single Field ! that serves as an intermediate result between the two redistributions. ! !\begin{verbatim} program Blk2BlkFldRedist #include "ESMF_Conf.inc" #include "ESMF.h" #define ESMF_METHOD "FieldRedistBlk2BlkSTest" !
