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.
