PARALLEL AND DISTRIBUITED COMPUTING A
Learning outcomes of the course unit
The objective of the course is to give the students the ability to operate on complex distributed computer systems. First the main technological and architectural evolutions in the field of high performance computing systems are discussed. Some instruments and methodology for parallel and distributed programming (such as MPI) are then introduced and discussed. Finally middleware infrastructure (such as GRID) are presented giving the ability to operate and construct simple solutions in a distributed environment.
