#6308: Add sp_counted_base_aix.hpp using AIX atomic operations
----------------------------------------+-----------------------------------
Reporter: aaron.riekenberg@⦠| Owner: pdimov
Type: Feature Requests | Status: new
Milestone: To Be Determined | Component: smart_ptr
Version: Boost 1.48.0 | Severity: Optimization
Keywords: |
----------------------------------------+-----------------------------------
Add sp_counted_base_aix.hpp that uses fetch_and_add and compare_and_swap
atomic operations available on AIX (see
http://publib.boulder.ibm.com/infocenter/aix/v6r1/index.jsp?topic=%2Fcom.ibm.aix.kerneltechref%2Fdoc%2Fktechrf1%2Ffetch_and_add.htm).
The average time for each iteration in the attached test.cpp was reduced
from 23 microseconds to 4.7 microseconds on a machine running AIX 5.3 with
VisualAge C++ 8.0.
