The OpenPALM coupler co-developed by ONERA and CERFACS has many features, and its use requires a dedicated training for physicists, computer scientists and developers of coupled applications. CERFACS engineers involved in its development teach this course.
 
Course topics:

1. Process management:
   • The first level of parallelism OpenPALM: launching parallel tasks in a context or MPI_2 MPI_1, OpenPALM units, chaining or coupling
   • Instrumentation of the computer codes (parallel or not) to make OpenPALM units, interfacing Fortran, C, C++ ;
   • Management of the second level of parallelism, launching parallel programs
   • Definition of the coupling algorithm: branches, blocks, control structures, synchronizations
   • Resource Management of CPU and memories, priorities
2. Information exchange between the coupled codes :
   • Instances of temporal objects, temporal interpolation
   • The toolkit, units of linear algebra, the interpolation of geophysical fields
   • Optimization of memory usage, the buffer, the Mailbuff, the memory slaves.

 
Real time monitoring of the application, the Performance Analyzer, debugging coupled applications.
