Topology Management and Standardization

We continued to work on the diffusion of our software and ideas in existing programming interfaces and standards tailored for HPC and parallel computing. In particular, we did integrate our TreeMatch algorithm in the Open MPI implementation of the Message Passing Interface, so as to provide enhanced Virtual Topology routines in MPI allowing the user to effectively create parallel applications taking into account both their behaviour and the characteristics of the underlying hardware. Our code is available in the master repository and should be available in an Open MPI distribution at some point in the next year (2016).

We also drafted and submitted a proposal to modify the MPI interface so that information regarding the underlying physical topology could be made available at the MPI application level. We plan to push our ideas during the next year so that our proposal can eventually make its way into the MPI standard.
