24 * ProblemIndex:
25 *
26 * The index has extra information stored in entries 3-8 that
27 * determine how the index gets "mapped" to finer index spaces.
28 *
29 * NOTE: For implementation convenience, the index is "pre-shifted"
30 * according to the values in entries 6,7,8. The following discussion
31 * describes how "un-shifted" indexes are mapped, because that is a
32 * more natural way to think about this mapping problem, and because
33 * that is the convention used in the input file for this code. The
34 * reason that pre-shifting is convenient is because it makes the true
35 * value of the index on the unrefined index space readily available
36 * in entries 0-2, hence, all operations on that unrefined space are
37 * straightforward. Also, the only time that the extra mapping
38 * information is needed is when an index is mapped to a new refined
39 * index space, allowing us to isolate the mapping details to the
40 * routine MapProblemIndex. The only other effected routine is
41 * SScanProblemIndex, which takes the user input and pre-shifts it.
42 *
43 * - Entries 3,4,5 have values of either 0 or 1 that indicate
44 * whether to map an index "to the left" or "to the right".
45 * Here is a 1D diagram:
46 *
47 * -- | * | unrefined index space
48 * |
49 * --> | * | . | * | refined index space (factor = 3)
50 * 0 1
51 *
52 * The '*' index on the unrefined index space gets mapped to one of
53 * the '*' indexes on the refined space based on the value (0 or 1)
54 * of the relevent entry (3,4, or 5). The actual mapping formula is
55 * as follows (with refinement factor, r):
56 *
57 * mapped_index[i] = r*index[i] + (r-1)*index[i+3]
58 *
59 * - Entries 6,7,8 contain "shift" information. The shift is
60 * simply added to the mapped index just described. So, the
61 * complete mapping formula is as follows:
62 *
63 * mapped_index[i] = r*index[i] + (r-1)*index[i+3] + index[i+6]
