Learning by doing :: MPI -- MPI Environmental Management, Part 2

This video is part of the new series called "Learning by doing :: MPI" which serves as an introductory course on MPI (Message Passing Interface). In this video we talked about environmental management in MPI! This topic corresponds to chapter 9 of the MPI standard v4.1. It is a short chapter on the contrary to the chapters we've had so far. We followed the same pattern as for "Datatypes in MPI" by dividing a chapter into digestible ~25 mins long parts. In part 2, we continued our discussion by talking about the second half of the example for hardware resource inquiry(MPI_Get_hw_resource_info). Then we moved on memory allocation functions namely MPI_Alloc_mem and MPI_Free_mem. And finally, we had time to talk about error handling. We mentioned pre-defined error handlers in MPI namely MPI_ERRORS_ARE_FATAL, MPI_ERRORS_ABORT and MPI_ERRORS_RETURN. But we didn't have enough time in this episode to present a code example.
