Introduction to Unified Parallel C (UPC) and Co-array Fortran (CAF)


Partitioned Global Address Space (PGAS) is a new model for parallel programming. Unified Parallel C (UPC) and Co-array Fortran (CAF) are PGAS extensions to C and Fortran. UPC and CAF are language extensions to C and Fortran. Parallelism is part of the language. PGAS languages allow any processor to directly address memory/data on any other processors. Parallelism can be expressed more easily compared to library based approaches as MPI. This course gives an introduction to this novel approach of expressing parallelism. Hands-on sessions (in UPC and/or CAF) will allow users to immediately test and understand the basic constructs of PGAS languages.

Cancelation policy

If you cannot come to the course, please send an email to the organizer as soon as possible. This would allow us to accept additional participants from the waiting-list. There is no cancelation fee.
NO-SHOW: Registered persons that do not cancel and do not show up without any reasons are blocked for the next year on any of our workshops (because it is to expensive to produce unused copies of the slides for them).
