9:05am - 10:05am Morning Invited Talk: The Crucial Role of CXL in
Future Memory Centric Computing Systems, by Tony Brewer from Micron
Technology Inc.

Session Chair: Yonghong Yan

Abstract: Previous attempts at providing commercial memory centric
computing systems have largely failed due to technologies that did not
live up to expectations. The emerging CXL standard is one of the
crucial technologies that will enable commercial memory centric
systems in the coming years. This talk will introduce the CXL
standard, how the CXL standard will enable efficient memory centric
computing and some of the market factors shaping current and future
versions of the standard. The HPC community will be able to leverage
these high-volume market features to realize memory centric computing
systems that will provide significant improvements in performance and
system energy consumption.

Bio: Tony Brewer is currently the chief architect in Micron’s Near
Data Computing group. He is the principal investigator on multiple
government contracts and manages a team of architects and researchers
focused on various processing in or near memory style architectures.
His career has been focused on system architecture in both the
high-performance computing as well as the telecommunications
industries. Prior to joining Micron in 2015, Tony Brewer was a
Co-founder and Chief Technology Officer for Convey Computer. Former
employers include Data General, Convex Computer, and Hewlett Packard.
Tony Brewer received his MS and BS degrees in Computer Engineering
from Purdue University and has over 175 filed patents.

11:30am - 12:00pm Invited Talk: The Path to Memory-Centric Computing
in ISO C++, by Christian Trott from Sandia National Laboratories

Session Chair: Ron Brightwell

Abstract: To make memory-centric compute devices impactful and
sustainable for a wide range of customers in HPC and beyond, we need
to find ways of leveraging their capabilities in language standards.
One of the prime targets for such efforts is the ISO C++ standard,
which has been the language of choice for HPC vendors to implement
programming models for accelerators, such as CUDA, HIP and SYCL. This
talk will discuss existing and upcoming capabilities in the C++
standard like std::mdspan and std::linalg, which enable memory-centric
application design. Based on concepts popularized in the Kokkos
ecosystem for performance portability, these new features allow the
design of algorithms that are memory location and memory layout aware,
that leverage advanced memory access capabilities, and that provide
customization points to plug special hardware-specific functionality
into C++ code without relying on non-standard APIs, such as intrinsics
and vendor-specific libraries.

Bio: Christian Trott is a high performance computing expert with
extensive experience designing and implementing software for modern
HPC systems. He is a principal member of staff at Sandia National
Laboratories, where he leads the Kokkos core team developing the
performance portability programming model for C++ and heads Sandia's
delegation to the ISO C++ standards committee. He also serves as
adviser to numerous application teams, helping them redesign their
codes using Kokkos and achieve performance portability for the next
generation of supercomputers. Christian is a regular contributor to
numerous scientific software projects including LAMMPS and Trilinos.
He earned a doctorate from the University of Technology Ilmenau in
theoretical physics with a focus on computational material research.

12:00pm - 2:00pm MCHPC'21 Lunch Break

2:00pm - 3:00pm Afternoon Invited Talk I: New Trends for sPIN-based
In-network Computing - from Sparse Reductions to RISC-V Acceleration,
by Torsten Hoefler from ETH Zürich, Switzerland, Presentation

Session Chair: Maya B. Gokhale

Abstract: Accelerated in-network computations promise significant
optimizations ranging from data-movement reductions to specialization
opportunities in processing elements. We show updates within the sPIN
(streaming Processing in the Network) network accelerator programming
model - the "CUDA for networking". There, we demonstrate 2x lower
required bandwidth for (sparse) reductions and a highly-optimized
packet processing design based on a low-power RISC-V multi-core
architecture.

Bio: Torsten is a full Professor of Computer Science at ETH Zürich,
Switzerland. Before joining ETH, he led the performance modeling and
simulation efforts of parallel petascale applications for the
NSF-funded Blue Waters project at NCSA/UIUC. He is also a key member
of the Message Passing Interface (MPI) Forum where he chairs the
"Collective Operations and Topologies" working group. Torsten won best
paper awards at the ACM/IEEE Supercomputing Conference 2010 (SC10),
EuroMPI 2013, SC13, SC14, SC19, IPDPS'15, ACM HPDC'15 and HPDC'16, ACM
OOPSLA'16, and other conferences. He published numerous peer-reviewed
scientific conference and journal articles and authored chapters of
the MPI-2.2 and MPI-3.0 standards. For his work, Torsten received the
ACM Gordon Bell Prize in 2019, the IEEE TCSC Award of Excellence (MCR)
in 2019, ETH Zurich's Latsis Prize in 2015, the SIAM
SIAG/Supercomputing Junior Scientist Prize in 2012, and the IEEE TCSC
Young Achievers in Scalable Computing Award in 2013. He was also
awarded the BenchCouncil Rising Star Award in 2020. Following his
Ph.D., he received the Young Alumni Award 2014 from Indiana
University. Torsten was elected into the first steering committee of
ACM's SIGHPC in 2013 and he was re-elected in 2016 and 2019. He was
the first European to receive many of those honors he also received
both an ERC Starting and an ERC Consolidator grant. His research
interests revolve around the central topic of "Performance-centric
System Design" and include scalable networks, parallel programming
techniques, and performance modeling. Additional information about
Torsten can be found on his homepage at htor.inf.ethz.ch.
