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