PGAS languages' support of a global name space facilitates the expression of parallel algorithms, since communication is implicit. This is especially convenient when writing irregular applications with data-dependent, dynamically changing communication patterns. However, programming in a shared memory style, with no explicit control of communication, may result in poor performance. The problem may be due to weaknesses of current implementations of PGAS languages or limitations inherent in these… CONTINUE READING
