|
! A map is an array of maps (cache_maps)
|
|
! A cache map is an array of keys and values sorted by keys
|
|
! A cache map has its own OpenMP lock
|
|
! To access a (key,value) pair in the map, the
|
|
! index of the cache_map in the map array is obtained
|
|
! by removing the first 15 bits of the key.
|
|
! The key in the cache_map is composed of the first
|
|
! 15 bits of the key. Therefore, it can be stored
|
|
! as integer*2 and is found by applying the map_mask
|
|
! to the initial key. The element are found in the
|
|
! cache_map using a binary search
|
|
!
|
|
! When using the map_update subroutine to build the map,
|
|
! the map_unique subroutine
|
|
! should be called before getting data from the map.
