ARCHER Shared Memory Programming with OpenMP @ EPCC

Nov 26, 2014, 9:00 AM → Nov 27, 2014, 5:30 PM Europe/London

PH216 (Durham, UK)

Please note the course will be held in Durham:

ARCHER, the UK's national supercomputing service, offers training in software development and high-performance computing to scientists and researchers across the UK. As part of our training service we are running a 2 day ARCHER Shared Memory Programming with OpenMP course at University of Durham on 26-27 November.

Almost all modern computers now have a shared-memory architecture with multiple CPUs connected to the same physical memory, for example multicore laptops or large multi-processor compute servers. This course covers OpenMP, the industry standard for shared-memory programming, which enables serial programs to be parallelised easily using compiler directives. Users of desktop machines can use OpenMP on its own to improve program performance by running on multiple cores; users of parallel supercomputers can use OpenMP in conjunction with MPI to better exploit the shared-memory capabilities of the compute nodes.

This two-day course will cover an introduction to the fundamental concepts of the shared variables model, followed by the syntax and semantics of OpenMP and how it can be used to parallelise real programs. Hands-on practical programming exercises make up a significant, and integral, part of this course.

Pre-requisite Programming Languages:

No prior HPC or parallel programming knowledge is assumed, but attendees must already be able to program in C, C++ or Fortran.  It is not possible to do the exercises in Java.

Computer access:

All course delegates will need to bring a wireless enabled laptop computer with them on the course.  If you have an EduRoam account please ensure this is set up beforehand.
