About the JLESC:

The purpose of the JLESC is to be an international, virtual organization
whose goal is to enhance the ability of member organizations and
investigators to make the bridge between Petascale and Extreme computing.
The founding partners of the JLESC are INRIA and UIUC. Further members are
ANL, BSC, JSC and R-CCS. UTK is an associate member.

JLESC involves computer scientists, engineers and scientists from other
disciplines as well as from industry, to ensure that the research
facilitated by the Laboratory addresses science and engineering's most
critical needs and takes advantage of the continuing evolution of computing
technologies. Find out more at https://jlesc.github.io/.

The JLESC community is looking forward to welcoming you at the 12th JLESC
workshop OpenDay!

Invited talks:

Invited talk 1: Fugaku: the first 'Exascale' supercomputer

Prof. Satoshi Matsuoka, Riken CCS

Fugaku is the first ‘exascale’ supercomputer of the world, not due to its
peak double precision flops, but rather, its demonstrated performance in
real applications that were expected of exascale machines on their
conceptions 10 years ago, as well as reaching actual exaflops in new breed
of benchmarks such as HPL-AI. But the importance of Fugaku is “applications
first” philosophy under which it was developed, and its resulting mission
to be the centerpiece for rapid realization of the so-called Japanese
‘Society 5.0’ as defined by the Japanese S&T national policy. As such,
Fugaku’s immense power is directly applicable not only to traditional
scientific simulation applications, but can be a target of Society 5.0
applications that encompasses conversion of HPC & AI & Big Data as well as
Cyber (IDC & Network) vs. Physical (IoT) space, with immediate societal
impact with its technologies utilized as Cloud resources. In fact, Fugaku
is already in partial operation a year ahead of schedule, primarily to
obtain early Society 5.0 results including combatting COVID-19 as well as
resolving other important societal issues and also go into full production
in moments time.


Satoshi Matsuoka from April 2018 has become the director of Riken CCS, the
top-tier HPC center that represents HPC in Japan, developing and hosting
Japan’s tier-one ‘Fugaku’ supercomputer which has become the fastest
supercomputer in the world in all four major supercomputer rankings, along
with multitudes of ongoing cutting edge HPC research being conducted,
including investigating Post-Moore era computing.

He had been a Full Professor at the Global Scientific Information and
Computing Center (GSIC), the Tokyo Institute of Technology since 2000, and
the director of the joint AIST-Tokyo Tech. Real World Big Data Computing
Open Innovation Laboratory (RWBC-OIL) since 2017, and became a Specially
Appointed Professor at Tokyo Tech in 2018 along with his directorship at

He has been the leader of the TSUBAME series of supercomputers that have
won many accolades such as world #1 in power-efficient computing. He also
leads various major supercomputing research projects in areas such as
parallel algorithms and programming, resilience, green computing, and
convergence of big data/AI with HPC.

He has written over 500 articles according to Google Scholar, and chaired
numerous ACM/IEEE conferences, including the Program Chair at the ACM/IEEE
Supercomputing Conference (SC13) in 2013. He is a Fellow of the ACM and
European ISC, and has won many awards, including the JSPS Prize from the
Japan Society for Promotion of Science in 2006, presented by his Highness
Prince Akishino; the ACM Gordon Bell Prize in 2011; the Commendation for
Science and Technology by the Minister of Education, Culture, Sports,
Science and Technology in 2012; the 2014 IEEE-CS Sidney Fernbach

Memorial Award, the highest prestige in the field of HPC; HPDC 2018
Achievement Award from ACM; and recently SC Asia 2019 HPC Leadership Award.

Invited talk 2: How a Community Software Ecosystem Perspective Helps to
Advance Science Goals in the Exascale Computing Project

Dr. Lois Curfman McInnes, Argonne National Laboratory

Teams in the U.S. Exascale Computing Project (ECP) are working toward
scientific advances on forthcoming exascale platforms, across a diverse
suite of applications in chemistry, materials, energy, Earth and space
science, data analytics, optimization, artificial intelligence, and
national security. In turn, these applications build on software
components, including programming models and runtimes, mathematical
libraries, data and visualization packages, and development tools that
comprise the Extreme-scale Scientific Software Stack (E4S).  E4S represents
a portfolio-driven effort to collect, test, and deliver the latest in
reusable open-source HPC software products, as driven by the common needs
of applications. E4S establishes product quality expectations and provides
a portal as a starting point for access to product documentation. This
presentation will discuss early experiences with how this software
ecosystem approach delivers the latest advances from ECP software
technology projects to applications, thereby helping to overcome software
collaboration challenges across distributed aggregate teams. A key lesson
learned is the need for close collaboration between teams developing
applications and reusable software technologies, as well as the need for
crosscutting strategies to increase developer productivity and software
sustainability, thereby mitigating technical risks by building a firmer
foundation for reproducible, sustainable science.


Lois Curfman McInnes is a senior computational scientist in the Mathematics
and Computer Science Division of Argonne National Laboratory. Her work
focuses on high-performance computational science and engineering, with
emphasis on scalable numerical libraries and community collaboration toward
productive and sustainable software ecosystems.  She serves as Deputy
Director of Software Technology in the DOE Exascale Computing Project.  She
also co-leads the IDEAS project, whose members are partnering with the
community to improve software productivity and sustainability as a key
aspect of advancing overall scientific productivity.  Lois has developed
numerical algorithms and software in the PETSc/TAO libraries. She is a SIAM
Fellow. She won the 2015 SIAM/ACM Prize in CSE and received an R&D 100
Award in 2009 (with collaborators); she also won an E.O. Lawrence Award in
2011 for outstanding contributions in research and development supporting
DOE and its missions.

Invited talk 3: High-Performance Deep Learning

Prof. Torsten Hoefler, ETH <http://www.ethz.ch/> Zurich

Abstract: Deep Learning is as computationally expensive as the most
challenging scientific computing applications. In this talk, we outline the
biggest challenges in training deep learning workloads and show how HPC
techniques can be used to improve the performance of training workloads. We
focus on model sparsity in the training process. This will be even more
important once the scientific computing community uses deep learning in
their workflows.
