This paper describes the design and implementation of a seamless MPI runtime environment, called MPI-Adapter, that realizes MPI program binary portability in different MPI runtime environments. MPI-Adapter enables an MPI binary program to run on different MPI implementations. It is implemented as a dynamic loadable module so that the module dynamically captures all MPI function calls and invokes functions defined in a different MPI implementation using the data type translation techniques. A prototype system was implemented for Linux PC clusters to evaluate the effectiveness of MPI-Adapter. The results of an evaluation on a Xeon Processor (3.8GHz) based cluster show that the MPI translation overhead of MPI sending (receiving) is around 0.028μs, and the performance degradation of MPI-Adapter is negligibly small on the NAS parallel benchmark IS.
