// This grid is activated with command line option -testMode Baseline
//
// ## THIS IS THE MAIN CLASS OF HPCSCAN AND THE REFERENCE IMPLEMENTATION ##
// ## ALL GRID IMPLEMENTATIONS SHOULD DERIVE FROM THIS CLASS ##
//
// Handle all grid data in hpcscan and all operations performed on grids
//
// ####################################################################################
// ## ##
// ## IMPORTANT: THIS FILE SHOULD NOT BE MODIFIED ##
// ## To implement specialization of some functions, you may create a new grid class ##
// ## that derives from this one. See for example: grid_CacheBlk.cpp ##
// ## ##
// ####################################################################################
//
// Unique definition for 1D, 2D and 3D grids
// For all axis, grid index is as follows:
//
// <------><-----><------><------------------><------><-----><----> --> Axis N (N=1,2 or 3)
// Offset Halo1 Layer1 Inner Points Layer2 Halo2 Pad
//
// Origin is when Inner starts
// All area have start and end index
// For example, axis 1, halo1:
// start at point index: i1Halo1Start
// end at point index : i1PadEnd
//
// For all dimension (1,2 or 3)
// grid values are stored in the 1D array grid_3d
// Points can be accessed by converting coordinates i1, i2, i3 as
// Myint64 ii = i1 + i2*n1 + i3*n2*n1 ;
//
// where n1, n2, n3 are the dimension of the 3D grid
// For 1D grids, only n1 is meaning full (and n2=n3=1)
// For 2D grids, only n1 and n2 are meaning full (and n3=1)
