* Process Affinity Algorithm:
*
* The code below works in 3 stages. The end result is an array of all the possible
* binding bitmaps for a system, based on the options specified.
*
* 1. Define all possible mapping "domains" in a system. A mapping domain is a group
* of hardware elements found by traversing the topology. Each traversal skips the
* number of elements the user specified in the mapping string. The traversal ends
* when the next mapping domain == the first mapping domain. Note that if the
* mapping string defines a domain that is larger than the system size, we exit
* with an error.
*
* 2. Define the number of possible binding domains within a mapping domain. This
* process is similar to step 1, in that we traverse the mapping domain finding
* all possible bind combinations, stopping when a duplicate of the first binding
* is reached. If a binding is larger (in # of PUs) than the mapping domain,
* the number of possible bindings for that domain is 1. In this stage, we also
* locate the first PU in each mapping domain for use later during binding.
*
* 3. Create the binding bitmaps. We allocate an array of bitmaps and fill them in
* with all possible bindings. The starting PU in each mapping domain is advanced
* if and when we wrap around to the beginning of the mapping domains. This ensures
* that we do not repeat.
*
