+ \brief Cache-line size definition
+
+ This file defines cache-line size constant. The constant is used many \p libcds algorithm
+ to solve false-sharing problem.
+
+ The value of cache-line size must be power of two.
+ You may define your cache-line size by defining macro -DCDS_CACHE_LINE_SIZE=xx
+ (where \p xx is 2**N: 32, 64, 128,...) at compile-time or you may define your constant
+ value just editing \p cds/user_setup/cache_line.h file.
+
+ The default value is 64.
