University of Vienna
For VASP, OpenACC is the way forward for GPU
acceleration. Performance is similar to CUDA, and
OpenACC dramatically decreases GPU
development and maintenance efforts. We’re
excited to collaborate with NVIDIA and PGI as an
early adopter of Unified Memory.

READ THE SPOTLIGHT
Meet Matthew Norman, a computational climate scientist that's
helping GPU Hackathon teams to weather the storm by
mentoring them on numerical algorithms and GPU programming.
In this profile series, we interview different mentors from across
all walks of life - those who strive to solve the greatest challenges
of our time, who work to spearhead technology advancements,
and who collaborate with the developer community to enable
scientific discoveries.
MENTOR SPOTLIGHT: MATTHEW NORMAN

It has been one year since the start of the pandemic and as the
world continues to adjust to the “new normal” of remote
collaboration, Simon Fraser University (SFU) kicked off the first
GPU hackathon of 2021.
Eight teams from 13 institutions representing various scientific
domains across computational fluid dynamics, climate modeling,
physics, molecular genetics, hydrology and chemistry, participated
in the digital event.

OpenACC continues to be the second most popular programming
model for GPUs on the ORNL Summit Supercomputer. Learn
more about Clacc, a Software Technology development effort to
develop production OpenACC compiler support for Clang and the
LLVM Compiler Infrastructure Project (LLVM).

BOOK: XcalableMP PGAS Programming Language
Edited by: Mitsuhisa Sato
XcalableMP is a directive-based parallel programming language based on
Fortran and C, supporting a Partitioned Global Address Space (PGAS)
model for distributed memory parallel systems. This open access book
presents XcalableMP language from its programming model and basic
concept to the experience and performance of applications described in
XcalableMP.
XcalableMP was taken as a parallel programming language project in the
FLAGSHIP 2020 project, which was to develop the Japanese flagship
supercomputer, Fugaku, for improving the productivity of parallel
programing. XcalableMP is now available on Fugaku and its performance
is enhanced by the Fugaku interconnect, Tofu-D.

Are you passionate about science and technology? Want to help
researchers accelerate their scientific codes or refine their AI projects?
Become a GPU Hackathon mentor and connect scientists to available
tools, techniques and GPU architectures. Sharpen your skills, learn about
the latest research efforts, and collaborate across the computing and
scientific community. Certification is available for HPC and AI pathways.
BECOME A GPU HACKATHON MENTOR
I strongly believe in the concept of community science. Scientists
should not be siloed; they should be continually contributing their
codes back and working collaboratively on projects at these GPU
Hackathons.
