NEC HPC Solution Special Site for ISC 2021

NEC have developed a Vector Engine (VE) for accelerated computing using vectorization, with the concept that the full application runs on the high performance VE and the operating system tasks are taken care of by the Vector Host (VH), which is a standard x86 server. This is the first time that the NEC SX series vector processor is integrated transparently into a Linux software environment. This allows the VE to concentrate on providing the best application performance. The SX-Aurora TSUBASA VE is flexible in sizing, can be water or air cooled, with an outstanding 48 GB HBM2 memory with a bandwidth of up to 1.53 TB/s and a comparatively low energy consumption with even better performance with the upcoming third generation of VE cards. Over the years a large amount of applications from different areas have been covered with especially good performance on simulation, weather forecasting, disaster prevention, resource exploration or oil and gas seismic imaging. Besides these applications the VE strongly supports Artificial Intelligence, Machine Learning, Big Data Analytics and Deep Learning to name a few.
On this page you'll find some examples explained in technical articles and in our upcoming webinar.

NEC Events in ISC 2021

Aurora Forum Webinar

09:00 - 12:00 on June 30, 2021 CEST

In Aurora Forum, we will show you the latest developments of the SX-Aurora TSUBASA Vector Engine. In addition to that our invited users will share their experiences on enhancing their research and daily work by using the vector architecture.

Introduction of SX-Aurora TSUBASA (PCIe card type vector computer)
Presenter: Tsutomu Takeda, Manager, NEC Corporation

Vector Engine for Geoscience -- From Oil & Gas to Carbon storage --
Presenter: Masashi Ikuta, Manager, NEC Corporation
Abstract

This presentation will focus on how Vector Engine can contribute to geoscience domain. The talk will start from where VE can shine in the Exploration and Production value chain of oil and gas. To prove this, some performance numbers including RTM(Reverse Time Migration), FWI(Full Waveform Inversion) and reservoir related calculation such as spmv will be discussed. This talk will also touch upon CO2 storage and monitoring which is becoming a hot topic today.

OpenMP Target Device Offloading for SX-Aurora TSUBASA
Presenter: Dr. rer. nat. Tim Cramer, IT Center, Group, High Performance Computing, Division, Computational Science and Engineering, RWTH Aachen University
Abstract

Driven by the heterogeneity trend in modern supercomputers, OpenMP provides support for heterogeneous systems since 2013. Having a single programming model for all kinds of accelerator-based systems decreases the burden of code porting to different device types.
The acceptance of this heterogeneous paradigm requires the availability of corresponding OpenMP compiler and runtime environments supporting different target device architectures. The LLVM/Clang infrastructure is designated to extend the offloading features for any new target platform. In this talk we present the opportunities for OpenMP target offloading to the NEC SX-Aurora TSUBASA vector engine based on the LLVM/Clang infrastructure.

Open Source LLVM for SX-Aurora TSUBASA
Presenter: Simon Moll, NEC Deutschland GmbH
Abstract

This talk covers the latest developments in the open source LLVM for SX-Aurora TSUBASA stack: automatic outer-loop vectorization, packed-mode support and OpenMP target offloading.

Delivering Powerful HPC with Altair and NEC on the SX-Aurora TSUBASA System
Presenter: Sujata Patnaik, Senior software engineer, Altair Engineering, Inc.
Abstract

Altair and NEC have teamed up to bring you the NEC SX-Aurora TSUBASA high-performance computing (HPC) architecture — based on NEC’s own Vector Engine (VE) — with fast, powerful workload management by Altair® PBS Professional®.

The addition of PBS Professional as NEC’s new solution for job scheduling will simplify access for customers who already use this workload manager to implement SX-Aurora TSUBASA.

In this session we will discuss the technical features that make this integration unique and highly competitive and how this optimized computing will make engineers and organizations more productive.

GigaIO and NEC HPC/AI Solutions: Composable Architectures with Next-Gen Interconnects and Vector Engines
Presenter: Marc Lehrer, VP, Global Sales, GigaIO
Abstract

This presentation is in two parts. 1) an overview of the GigaIO and FabreX™ universal fabric, and 2) the GigaIO/NEC SX-Aurora TSUBASA benchmarking results.

GigaIO has invented the first truly composable cloud-class software-defined universal infrastructure fabric, empowering users to accelerate workloads on-demand, using industry-standard PCIe Express technology. The company’s technology optimizes cluster and rack system performance, and greatly reduces total cost of ownership. With the innovative GigaIO FabreX open architecture, data centers can scale up or scale out the performance of their systems, enabling their existing investment to flex as workloads change over time.

Products

Building on the successful evolution of the SX-series of vector-supercomputers the next generation of this product line clearly focusses on all aspects of efficiency, NEC have combined the flexibility of a cluster with the raw power of the NEC Vector Engine Processor.

Vector Supercomputing Solution

The NEC LX Series covers x86 based computer platforms, and accompanying network, software and infrastructure. NEC has developed a solution based on the changes that had taken place in the automotive sector for simulation, which in turn, later opened up a larger market for LX.

Scalar Supercomputing Solution

Technical Articles

The SX-Aurora TSUBASA is supported by many hardware and software technologies. In this section, we wanted to show you technical details and some examples for implementing and using the vector engine with little effort.
