Member Function Documentation

template<typename DType>
static constexpr unsigned int JResourcePool< DType >::Get_CacheLineSize ( void  )
inlinestatic

Returns the cache line size for the processor of the target platform.

The cache line size is useful for creating a buffer to make sure that a variable accessed by multiple threads does not share the cache line it is on. This is useful for variables that may be written-to by one of the threads, because the thread will acquire locked access to the entire cache line. This blocks other threads from operating on the other data stored on the cache line. Note that it is also important to align the shared data as well. See http://www.drdobbs.com/parallel/eliminate-false-sharing/217500206?pgno=4 for more details.
