/*
* The hierarchical place tree for a shared memory system is specified as an XML
* file containing the hierarchy of memory spaces it contains. In general, this
* hierarchy is multi-layered and may include a separate layer for system
* memory, L3 caches, L2 caches, L1 caches, etc.
*
* Each layer is described by two properties: a type and a count/num. For
* example, the type may be "mem" whose contents are explicitly managed by the
* programmer, or a "cache" whose contents are automatically managed. The count
* refers to the fan-out at a given level. For example, a machine with main
* memory feeding to two sockets each with their own L3 cache would have a count
* of 2 for the L3 layer.
*
* An example HPT specification is below. This specification describes a machine
* with a single system memory, two L3 caches, each of which fans out to 6 L1/L2
* caches.
*
* <HPT version="0.1" info="2 hex core2 Intel Westmere processors">
* <place num="1" type="mem">
* <place num="2" type="cache"> <!-- 2 sockets with common L3 in each -->
* <place num="6" type="cache"> <!-- 6 L2/L1 cache per socket -->
* <worker num="1"/>
* </place>
* </place>
* </place>
* </HPT>
*
* While homogeneous systems will usually have this singly-nested structure, a
* machine with multiple types of memory sitting below system memory may have
* multiple elements at the same nesting level, e.g. both L3 and GPU device
* memory at the same level in the hierarchy.
*
* read_hpt parses one of these XML files and produces the equivalent place
* hierarchy, returning the root of that hierarchy. The schema of the HPT XML
* file is stored in $HCLIB_HOME/hpt/hpt.dtd.
