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 provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

Programming experience in Fortran or C, some knowledge about parallel programming


Dr. Rolf Rabenseifner from HLRS


Each participant will get a paper copy of all slides.


Academic participants (i.e., members of universities or public research institutions) from Europe or PRACE countries: Please apply through the PATC web page. After your registration, you will receive an automated "congratulation"-email about your successful registration. This email implies that you have a guaranteed seat in the course and you should organize your travel.
All other participants (not from academia, or from outside Europe), or if the PATC web page is temporarily unavailable, please apply through this online registration form
Course number is 2016-UPC1.

Extended Deadline

for registration is May 15, 2016 (extended deadline).
Late registrations after the deadline are still possible but maybe with reduced quality of the handouts.


Members of German universities and public research institutes: none.
Members of universities and public research institutes within EU or PRACE-member countries: none.
Members of other universities and public research institutes: 120 EUR.
Others: 400 EUR.
(includes coffee breaks)

HLRS is part of the Gauss Centre for Supercomputing (GCS), which is one of the six PRACE Advanced Training Centres (PATCs) that started in Feb. 2012. The mandate for the PATCs is as follows: "The PRACE Advanced Training Centres will serve as European hubs of advanced, world-class training for researchers working in the computational sciences." (see D3.2.3)
This course is a PATC course, see also the PRACE Training Portal and Events. For participants from public research institutions in PRACE countries, the course fee is sponsored through the PRACE PATC program.

HLRS is also member of the Baden-Württemberg initiative bwHPC-C5.
This course is also provided within the framework of the bwHPC-C5 user Support
