I'm not entirely sure I understand that ... as I understand it the tier-1 always publishes an SI00 of 1000 and uses the internal PBS scaling to adjust for the speed of each WN. How do you set that scaling factor? I would assume that you must do it by a per-core rating because otherwise your CPU time limits would be very wrong for single-core jobs running on multi-core nodes, and the APEL accounting would also be wrong ...
