Brent's theorem for parallel algorithms

WebThe goal of this book is to cover the fundamental concepts of parallel computing, including models of computation, parallel algorithms, and techniques for implementing and evaluating parallel algorithms. Our primany focus will be hardware-shared memory parallelism. For implementations, we use a C++ library, called PASL, WebBrent’s theorem With T1, Tp, T∞ defined as above, Since T1/p optimal, we see that T∞ allows us to assess how far off our algorithm performs relative to the best possible …
