=====Journal of Lessons, SPD year 2017-2018====
====Journal====
  * 19/02/2018 **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.
  * 23/02/2018 **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).
  * 26/02/2018 **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, indexed, hindexed, struct; commit, free) and examples.
  * 02/03/2018 **MPI** Lab session – Basic program structure. Simple ping-pong program; adapting to available parallelism, extending to multi-process interaction; cut&paste and if-based programming pitfalls in MPI. Assigned homework: using point-to-point with simple primitive datatypes, performing and checking some computation; using derived datatpyes. 
  * 09/03/2018 **MPI** point to point communication modes (MPI_BSEND, MPI_SSEND; MPI_RSend usage); non-blocking communication (Wait and Test group of primitives, semantics, MPI_Request object handles to active requests); canceling and testing cancellation of non-blocking primitives (issues and pitfalls, interaction with MPI implementation, e.g. MPI_finalize); communicators and groups (communicator design aim and programming abstraction, local and global information, attributes and virtual topologies, groups as local objects, primitives for locally creating and managing groups); intracommunicators (basic primitives concerning size, rank, comparison); communicator creation as a collective operation, MPI_Comm_create basic and general case.
