====Journal====
* 07/03/2010 ** Introduction to the course** --- Aim and purpose, program, structure, rules and kind of final tests. --- ** Message Passing Interface, Part 1 ** --- The MPI standard, brief history and purpose. Message Passing programming and portability, functional and performance portability. The library approach of MPI. MPI basic concepts: communicators.
* 08/03 ** Message Passing Interface, Part 1 continued ** --- MPI basic concepts: communicators, point to point primitives, collective primitives, datatypes; communication semantics in MPI: envelopes, local/global completion, (non)blocking operations, communication modes. Opaque Objects. Primitive datatypes.
* 11/03 ** MPI, Part 2 ** --- MPI Datatypes: role in MPI, primitive datatypes, derived datatypes. Datatypes and data conversion/packing/unpacking. Basic Send and Receive and their differences: checking communication result, count of received items, asymmetric receives (wildcard TAG and SOURCE) and the status opaque object in receives. Derived datatypes as //local// opaque objects. Typemaps and type signatures of an MPI datatype. Type signatures and send-receive compatibility, different typemaps corresponding to a same type signature. Basic datatype constructors MPI_CONTIGUOUS, MPI_VECTOR.
* 14/03 __No lesson__
* 15/03 __No lesson__
* 18/03 ** MPI, Part 3 ** --- Array and Struct Datatype Constructors: MPI_HVECTOR, MPI_INDEXED, MPI_HINDEXED, MPI_INDEX_BLOCK, MPI_STRUCT; effect of extent and size in composing datatypes in memory, upper bound and lower bound markers, related auxiliary functions: MPI_GET_ADDRESS, MPI_TYPE_SIZE, MPI_TYPE_GET_EXTENT, MPI_TYPE_CREATE_RESIZED, MPI_TYPE_GET_TRUE_EXTENT. Commit and free operations, MPI_TYPE_DUP. MPI_INIT and MPI_FINALIZE.
* 21/03 ** MPI, Part 4 ** --- MPI Collective operations (except the ALLTOALLW and reduce/scan operations).
* 22/03 ** MPI, Part 5 ** --- MPI Collective operations ALLTOALLW and reduce/scan; user-defined reduction operators. Groups and Communicators: semantics (local versus global), creation and manipulation primitives.
* 25/03 24/03 ** MPI, Part 6 ** --- Communication modes: Buffered, Ready, Synchronous. Attaching buffers to MPI: semantics and primitives. Incomplete communications: semantics, MPI_REQUEST opaque objects, MPI_GET_STATUS. Semantics of Incomplete Sends with modes, Incomplete Receive. Semantics and use of MPI_TEST and MPI_WAIT primitives in the plain, *SOME, *ANY and *ALL variants. Brief description of MPI_CANCEL and MPI_REQUEST_FREE.
* 28/03 ** Assist, Part 1 ** --- Recap on Parallel Skeleton Languages, introduction to a line of SPP languages (co-)developed at the C.S. Dept. : P3L, OcamlP3L, SKIE, ASSIST. See Assist Tutorials on the course main page.

* 05/04 __No lesson__
* 08/04 ** MPI recap ** --- we will have a short survey of MPI to help who started the course late to get on par with the rest of the class.
* 11/04 ** Assist Part 4 **
* 12/04 ** MPI Lab ** Program with multiple parallel modules in MPI. See document at the end of this web page.
* 15/04 ** MPI Lab ** Program with multiple parallel modules in MPI. See document at the end of this web page. POLL FOR SETTING UP AN EXTRA LESSON EACH WEEK IN MAY : [[http://www.doodle.com/red98k9t29p49ta6|Doodle poll]] Correction : please disregard previous doodle poll.
* 29/04 **Coarse grain and Parallel Bridging models** --- Recap of the RAM model; the Parallel RAM (PRAM) model of algorithmic cost. Theoretical vs realistic cost models, and the quest for parallel bridging models. Modeling communication abstracting away from the network structure: QSM and LogP (mention) and the BSP model. Superstep model, cost of a superstep, cost of an algorithm. BSP can be a programming model: mention of BSPlib and NestStep / BlockLib \\ Doodle poll to fill : [[http://www.doodle.com/4qdx3em9y4mbwrsv|New Doodle poll]] -- please report **NO** for unavailable times, **YES** if you are sure that the time slot is free, and **(yes)** if you don't know for sure.

* 16/05 ** From Grids to Clouds (and beyond ?) ** Very short survey of Grids and Service oriented architectures. Differences between Grids and Clouds. Basic definitions related to Clouds: Public/Private/Hybrid clouds, Cloudbursting. Introduction to the Contrail Research Project and to Cloud Federations.
* 17/05 ** Cloud computing: Open Nebula **
