- 20/02/2017 Course introduction Parallel programming frameworks and high-level approach to parallel programming over different platforms: MPI, TBB and OpenCL as main examples; course organization and prerequisites; reference books and studying material.
MPI (Message Passing Interface) standard : brief history and aim of the standard, single program / multiple data execution model, compilation and linkage model; issues in supporting multiple programming languages and uses (application, utility library and programming language support) with a static compilation and linkage approach. Portability in parallel programming: functional and non-functional aspects, performance tuning and performance debugging. - 22/02/2017 MPI basic concepts : MPI as a parallel framework that supports a structured approach to parallel programming. Basic concepts of MPI: communicators (definition, purpose, difference between inter and intra-communicators, process ranks); point to point communication (concepts of envelope, local/global completion, blocking/non-blocking primitive, send modes); collective communications (definition, communication scope, global serialization, freedom of implementation in the standard); MPI datatypes (basic meaning and use, primitive / derived datatypes, relationship with sequential language types).
- 27/02/2017 MPI : MPI library initialization and basic MPI usage; point to point communication semantics (buffer behaviour, receive, wildcards, status objects, MPI_PROC_NULL), basic and derived MPI datatypes (purpose as explicitly defined meta-data provided to the MPI implementation, multiple language bindings, code-instantiated metadata, examples). MPI datatypes (semantics, typemap and type signature, matching rules for communication, role in MPI-performed packing and unpacking); core primitives for datatype creation ( MPI_Type_* : contiguous, vector, hvector, commit, free) and examples.
