/* ERROR/WARNING messages:
E: Could not create 3d grid of processors
The specified constraints did not allow a Px by Py by Pz grid to be
created where Px * Py * Pz = P = total number of processors.
E: Processors twogrid requires proc count be a multiple of core count
Self-explanatory.
E: Could not create twolevel 3d grid of processors
The specified constraints did not allow this style of grid to be
created.
E: Could not create numa grid of processors
The specified constraints did not allow this style of grid to be
created. Usually this is because the total processor count is not a
multiple of the cores/node or the user specified processor count is >
1 in one of the dimensions.
E: Cannot open custom file
Self-explanatory.
E: Unexpected end of custom file
Self-explanatory.
E: Processors custom grid file is inconsistent
The vales in the custom file are not consistent with the number of
processors you are running on or the Px,Py,Pz settings of the
processors command. Or there was not a setting for every processor.
E: Cannot open processors output file
Self-explanatory.
