An introduction to parallel programming using Message Passing with MPI

Message Passing is presently a widely deployed programming model in massively parallel high performance computing. Message Passing is suitable for programming a wide range of current computer architectures, ranging from multi-core desk top equipment to the fastest HPC systems in the world, offering several hundred thousand processing elements.

This online course is at the beginners level and assumes no prior experience in parallel computing. The concepts behind message passing and distributed memory computing will be introduced and the syntax of the key MPI calls will be explained. The course will include point-to-point communications, non-blocking communication and the collective communications calls.  Live demonstrations and practical sessions to deepen the understanding of the lectures will be part of the course. At the end of the course participants should be able to write their own MPI programs at an intermediate level. The teaching language will be English.

The course forms part of the NAISS training program.  It is offered as a collaborative effort between HPC2N, LUNARC and PDC.

Eligibility

It is open to NAISS users, prospective NAISS users and academics throughout the Nordic region.

Pre-requisites

Participants should be able to write simple programs in one or more of C, C++, Fortran or Python.  Basic knowledge of UNIX/LINUX is beneficial. 

For the hand-on part participants should have access to a laptop or desktop computer, which is connected to the internet.   Participants with accounts or course accounts on COSMOS at LUNARC can access the system via ThinLinc or ssh.

Time and location

The course will run on 21, 22, 28 and 29 November 2023.  The course will start at 09:00 and finish at 12:30 each day.

The course will be taught over zoom.  A zoom link will be provided to registered participants prior to the event.
