-// This program allocates and accesses
-// a number of blocks of memory, one or more
-// for each thread that executes. Blocks
-// are divided into sub-blocks called
-// pages, and pages are divided into
-// sub-blocks called cache lines.
-//
-// All pages are collected into a list.
-// Pages are selected for the list in
-// a particular order. Each cache line
-// within the page is similarly gathered
-// into a list in a particular order.
-// In both cases the order may be random
-// or linear.
-//
-// A root pointer points to the first
-// cache line. A pointer in the cache
-// line points to the next cache line,
-// which contains a pointer to the cache
-// line after that, and so on. This
-// forms a pointer chain that touches all
-// cache lines within the first page,
-// then all cache lines within the second
-// page, and so on until all pages are
-// covered. The last pointer contains
-// NULL, terminating the chain.
-//
-// Depending on compile-time options,
-// pointers may be 32-bit or 64-bit
-// pointers.
