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. (This course has the same content as the course in spring.)

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).


maximum of 42 participants in Stuttgart and Kassel, 35 in Dresden and Aachen, 34 in Garching, 26 in Jülich, 20 an der TUHH (according to the seats in the rooms).


Each participant will get a paper copy of all slides.
The MPI-1 part of the course is based on the MPI course developed by the EPCC Training and Education Centre, Edinburgh Parallel Computing Centre.
If you want, you may also buy copies of the standards MPI-2.2 (Hardcover, 17 Euro) and OpenMP 3.0 (about 8 Euro).
Most material of the course (including the audio information) can also be viewed in the ONLINE Parallel Programming Workshop.
