Abstract: E#ciently supporting a shared memory paradigm in a large-scale multiprocessor generally involves some form of data caching. One of the drawbacks of caching shared data is the cost of keeping the multiple copies coherent. One source of unnecessary coherency overhead is caused by a problem known as false sharing . Unfortunately, the lack of a precise, universally accepted, definition of false sharing hinders research to detect and eliminate the problem. We articulate our intuitive notion of false ... (Update)
