The post-K is the successor of the Japanese flagship supercomputer, K.
RIKEN and Fujitsu have developed a new Arm-SVE enabled processor,
called A64FX, for the Post-K system. The processor is designed for
energy-efficiency and sustained application performance. The system
will be installed in the next year. In this talk, the features and
some preliminary performance of the post-K system will be presented,
as well as the schedule of the project and supported software.

The HPC segment is in the process of transforming from grid architectures to private and hybrid cloud infrastructures while customers strive to run with maximum performance in their critical HPC environments.
Driven by advanced computing technologies commonly found in big data analytics, AI/Machine learning and edge computing, the modern HPC infrastructure requires new design approaches that rely on having a choice of multiple hardware architectures, availability of accelerators/GPGPUs and presence of high performance interconnects to deliver highly scalable solutions.
Join us for a panel discussion on how standardization and open source software provide common foundation across all major computing architectures and minimize the impact of future hardware decisions on user workloads and applications. On the panel:

• Yan Fisher (Moderator) - Global Evangelist, Red Hat
• Mark Hambleton - VP open source software, Arm
• Mitsuhisa Sato - Deputy Director, RIKEN Center for Computational Science
• Jacob Smith - Co-founder and CMO, Packet
• Rafael Tinoco - HPC Technical Lead, Linaro

LLVM has reached a sufficient level as a compiler for system programming.
However, there are several problems as compilers for HPC applications.
Therefore, we are improving and enhancing LLVM for HPC.
In this presentation, we report our activities on register allocation,
vectorization, and software pipelining for AArch 64.
Also, we talk about some optimizations required to further
improve the performance of HPC applications.

The Vanguard program looks to expand the potential technology choices for leadership class High Performance Computing (HPC) platforms, not only for the National Nuclear Security Administration (NNSA) and the Department of Energy (DOE), but also for the wider HPC community. Specifically, there is a need to expand the supercomputing ecosystem by investing and developing emerging, yet-to-be-proven technologies and address both hardware and software challenges together and prove-out the viability of such novel platforms for production workloads.

The first deployment of Vanguard is Astra, a prototype Petascale ARM supercomputer sited at Sandia National Laboratories. This talk will focus on the architectural details of Astra, as well as the Advanced Tri-Lab Software Environment (ATSE) and significant investments being made towards the ARM software ecosystem. Furthermore, we will share initial performance results, first experiences, and outlay several planned research activities.
