Description on Sourceforge under System Test #XXXXX !------------------------------------------------------------------------- !ESMF_SYSTEM_TEST String used by test script to count system tests. !========================================================================= !BOP ! ! !DESCRIPTION: ! System test FieldRedistArb2Arb. ! ! This system test checks the functionality of the grid distribution ! routines by redistributing data from one Field arbitrarily distributed ! structure to another Field that has been distributed arbitrarily ! 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, both with the semi-random ! arbitrary 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 Arb2ArbFldReDist !
