00058  * Description:
00059  *
00060  * This is the description of the memory hierarcy.  It is only used
00061  * to determine how to SNL transform and for prefetching.  There's no
00062  * need to model memory hierarchy levels that are to be ignored during
00063  * transformation.  E.g. typically, there's no need to model main
00064  * memory.
00065  *
00066  * For instructions on adding new memory hierarchy configuration
00067  * parameters, see the header for config_lno.h.
