M8 Mesh Specifications

a proposal for volume output box. With these specifications, the box to be less than 14 GB in memory requirement to fit into a single node. By skipping second grid,

    10125 NX            = x model dimension in nodes
     5000 NY            = y model dimension in nodes
     1060 NZ            = z model dimension in nodes

      75  NPX           = number of procs in the x direction
      40  NPY           = number of procs in the Y direction
      10  NPZ           = number of procs in the Z direction

Volume output range should be this way:

    1001 NBGX2         = first x node to contain receivers
    9000 NEDX2         = last x node to contain receivers
       2 NSKPX2        = skip of nodes containing x receivers
     501 NBGY2         = first y node to contain receivers
    4500 NEDY2         = last y node to contain receivers
       2 NSKPY2        = skip of nodes containing y receivers
       1 NBGZ2         = first z node to contain receivers
     900 NEDZ2         = last z node to contain receivers
       2 NSKPZ2        = skip of nodes containing z receivers

      80 NTISKP2       = time skip of seismograms (every nth step)

This would generate 4000x2000x450x4bytes --> 13.4GB each component and step, that is 39 TB size outputs in total.
