Helper modules
--------------
cg-makea.chpl -- common module for building A's sparse indices and values

cg-makea-commented.chpl -- a commented version of the above


CG codes
--------
cg-core.chpl -- just a sketch of the core algorithm; probably out-of-date

cg.chpl -- ???

cg-commented.chpl -- a commented version of the above

cg-sparse.chpl -- the sparse implementation of the benchmark

cg-dense.chpl -- executes CG using a dense array (and currently, an
                 8x8 problem size)

cg-ideal.chpl -- an ideal version to strive for making work



MakeA tests
-----------
cg-makea1.chpl -- test for building sparse matrix A -- verifies indices
                  and values being inserted

cg-makea1-small.chpl -- small 8x8 version of the above

cg-makea2.chpl -- similar, but verifies final matrix structure and values

cg-makea2-small.chpl -- similar, but only makes an 8x8 sparse matrix

cg-makea3.chpl -- similar, but runs index generator before makea
                  iterator in order to make sure that it still gets
                  the right result

cg-makea1-small-sparse.chpl -- a sparse version that builds the
                               domain first and then the array.
                               Currently tested with an 8x8 array.

cg-makea2-small-sparse.chpl -- same as the above, but builds both
                         simultaneously;

cg-makea1-sparse-sort.chpl -- a version of the above that sorts the
                              indices before inserting them on the
                              full problem size

cg-makea1-small-sparse-countInds.chpl -- version of the above that
                                         simply counts the indices

cg-printa.chpl -- a version of the above that prints out the sparse
                  domain and array

Misc tests
----------
cg-enumDomArr.chpl -- test for problem parameters using an enumerated
                      domain

cg-arithDomArr.chpl -- test for problem parameters using an arithmetic
                       domain
