Modern MPI applications have diverse communication requirements, with trends showing that they are moving from static communication requirements to more dynamic and evolving communication requirements. However, MPI libraries, which integrate MPI applications with the hardware, are not flexible enough to accommodate these diverse needs. This lack of flexibility leads to degraded performance of the applications. In this paper, we present the design of a protocol development framework and an MPI library implemented using our proposed framework that support compile-time and boot-time protocol configuration, as well as runtime protocol reconfiguration based on dynamic application requirements. Experimental results on the initial prototype of this design show that this prototype is able to dynamically reconfigure at runtime to optimize bandwidth under changing MPI requirements.
