I regularly needed it for debugging some NUMA related problems and they still happen moderately often even today. I think the right approach here, to limit output, would be to figure out a more compact output format, perhaps using a matrix in a table or simply printing multiple pair per line. -Andi > -- ak@linux.intel.com -- Speaking for myself only.
