Description on Sourceforge under System Test #79497 !------------------------------------------------------------------------- !ESMF_MULTI_PROC_SYSTEM_TEST String used by test script to count system tests. !========================================================================= !BOP ! ! !DESCRIPTION: ! System test ConcurrentComponent. ! Concurrent, Concurrent Component test. ! This system test demonstrates the use of ESMF coupling framework ! to couple 2 gridded components with 1 coupler component. The coupler ! component runs on the union of the PETs that are exclusively allocated ! to each individual gridded component. ! ! Component 1 exports data to the coupler which then redistributes the ! data to component 2. Component 1 and 2 runs concurrently because they ! reside on different PETs. The coupler also runs concurrently across PETs, however ! on each individual PET, it runs sequentially. In other words, each PET ! has a copy of the coupler that executes different code simultaneously. ! So this pattern constitutes a SPMD concurrency model. ! ! It's possible to reschedule the component execution by introducing wait ! and block semantic. Components on exclusive sets ! of PETs can be rescheduled to execute sequentially. ! ! This system test exercises the ESMF coupling framework to perform ! quick sort that can be useful in search engine, gnome sequencing, etc. ! The sorting result of component 1 is redistributed to component 2. Component ! 2 verifies the sorting result. ! ! This system test also captures the design of a typical hierarchical ! climate model with a coupler component that couples individual gridded components ! (e.g. atmosphere, land, and ocean). ! !\begin{verbatim} program ConcurrentComponent #include "ESMF_Conf.inc" #include "ESMF.h" #define ESMF_METHOD "ConcurrentComponent" !
