The race towards Exascale computing is on, and a lot of stress is put
on researchers to break the boundaries of productivity and efficiency
imposed by traditional programming models.
Partitioned Global Address Space (PGAS) languages are an
effective alternative, and the most promising path towards
sustainable programming environments for exascale machines.
Languages such as UPC, Fortran, Chapel, and X10 are now more widely
available than ever, thanks to increased support from vendors and
open-source communities. PGAS models also take the form of
meta-languages and libraries, such as Unified Parallel C++ (UPC++),
Co-Array C++, OpenSHMEM, MPI-3 and Global Arrays.
These have the benefit of being integrated with existing languages,
simplifying the learning curve for existing programmers.

Significant improvements in the availability of PGAS compilers and
support software have been achieved in the last few years; these
open up more opportunities than ever for researchers
and developers to test new strategies and port applications to more
demanding requirements.

Following on the success of PAW16, we invite you to take part
in the second PGAS Application Workshop, and to join
its vibrant and diverse community of researchers and developers.
