  • Mô tả: As parallel systems are commonly being built out of increasingly large multicore chips, application programmers are exploring the use of hybrid programming models combining MPI across nodes and multithreading within a node. Many MPI implementations, however, are just starting to support multithreaded MPI communication, often focussing on correctness first and performance later. As a result, both users and implementers need some measure for evaluating the multithreaded performance of an MPI implementation. In this paper, we propose a number of performance tests that are motivated by typical application scenarios. These tests cover the overhead of providing the _ _ level of thread safety for user programs, the amount of concurrency in different threads making MPI calls, the ability to overlap communication with computation, and other features. We present performance results with this test suite on several platforms...
