     234This multi-threaded parallel application is the port of the SPLASH OCEAN benchmark on the GIET_VM OS.
     235
     236This application studies the role of eddy and boundary currents in influencing large-scale ocean movements. 
     237The ocean is modeled as dynamically allocated four-dimensional arrays for grid data storage, distributed in all clusters.
     238The two main parameters are :                                             
     239 * M : MxM define the grid size. M must be (power of 2) + 2.  (from 36 to 1026).             
     240 * N : the number of threads is defined by the number of processors (one thread per processor. N must be power of 4.
     241The (M * M) grid modeling the ocean is split in (rootN * rootN) sub-grids (one square surged per thread.
     242If the sub-grids are large enough, we expect most of the memory access to be local.
     243
     244It requires one TTY terminal shared by all threads.
