Abstract

Many tools, including performance analysis tools, tracing libraries and application level checkpointers, add piggyback data to messages. However, transparently implementing this functionality on top of MPI is not trivial and can severely reduce application performance. We study three transparent piggyback implementations on multiple production platforms and demonstrate that all are inefficient for some application scenarios. Overall, our results show that efficient piggyback support requires mechanisms within the MPI implementation and, thus, the interface should be extended to support them.
