Routing circuit for computer resource topology

A method, comprising:

• receiving, at a routing circuit, an address indicative of a particular resource of a plurality of resources within a computer system, wherein the plurality of resources are organized according to a routing topology having a plurality of dimensions that includes first and second dimensions, the first dimension having n routing options, wherein 2a<n<2b, a and b are positive integers, and b=a+1;
• and
• masking, by the routing circuit using a first mask value, the address to produce a first masked value having more than b bits;
• and
• determining, by performing a mod-n operation on the first masked value, a first routing value for the first dimension, the first routing value being usable to access the particular resource.

An apparatus, comprising:

• a memory subsystem of a computer system having storage locations organized according to a topology having a plurality of dimensions that includes first and second dimensions, the first dimension having n routing options, wherein n is a non-power-of-two positive integer, and wherein 2b is the smallest power-of-two integer greater than n;
• a routing circuit configured to:
• receive an address indicative of a particular storage location within the memory subsystem, wherein a subset of bits in the address jointly encodes routing selections for the first and second dimensions;
• and
• determine a first routing value for the first dimension by performing a mod-n operation on a first masked value formed from the address, wherein the first masked value includes more than b bits, and wherein the first routing value is usable to select the particular storage location.
