Abstract
In this paper we evaluate the current status and performance of several MPI implementations regarding two chapters of the MPI-2 specification. First, we analyze whether the performance using dynamically created communicators is comparable to the approach presented in MPI-1 using a static communicator for different MPI libraries. We then evaluate whether the communication performance of one-sided communication on current machines represents a benefit or a disadvantage to the end-user compared to the more conventional two-sided communication.
