/* 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.
