Colfax affords computing options with the NEC SX-Aurora TSUBASA / Vector Engine Accelerator of the second technology

SANTA CLARA, Calif., February 2, 2021 – Colfax International, a leading provider of HPC and AI solutions, today announced the availability of accelerated computing solutions that include the Generation 2 NEC SX-Aurora TSUBASA / Vector Engine accelerators with Type 20 (VE20) processors. These solutions are implemented in workstation and server form factors. The first available solution in the range, the Colfax CX2400a-VE8 2U rack mount server, based on an AMD EPYC 7002 processor, supports up to four NEC SX-Aurora TSUBASA / Vector Engine accelerators.

NEC’s Vector Engine accelerator processor is a massive SIMD architecture that balances the processing power of vector computing cores with the fast data movement capability of on-chip, high-bandwidth memory (HBM). For example, a VE20B with eight cores delivers an arithmetic performance of 2.45 TFLOP / s with double precision (307 GFLOP / s per core) and a memory bandwidth of 1.53 TB / s (192 GB / s per core) with 48 GB On -Chip memory with high bandwidth (HBM). According to the company, this is higher than any other accelerator with SIMD architecture in a power envelope of 300 W and a PCIe x16 form factor.

The Colfax solutions, which support Generation 2 of the NEC SX-Aurora TSUBASA / Vector Engine accelerators, can provide significant performance increases at the application level for traditional (e.g. HPC) and also non-traditional (e.g. high-performance data analytics or sparse data-based AI ) offer / ML) applications by using only an existing CPU-specific or SIMD-enabled application source code. With features like auto-vectorization and auto-parallelization, or with minimal changes to existing CPU code such as compiler optimization stage or pragmas (compiler instructions in code), users can enjoy the full power of the Vector Engine accelerator processor with no special constructs required. This results in a low total cost of ownership and good performance per watt of application level efficiency for users.

Successful use cases of the NEC SX-Aurora TSUBASA / Vector Engine accelerator architecture include fluid dynamics / analysis (CFD) for aerospace, weather / climate, geosciences, seismic imaging / reservoir simulations for the O&G industry, and financial risk analysis simulations Monte Carlo based, statistical machine learning, numpy, data frame, recommendation engine, demand / price prediction and deep learning. A novel use case for computer science, which is accelerated by the accelerator NEC SX-Aurora TSUBASA / Vector Engine, is the simulation of quantum glow, a Segway in the quantum computer initiatives of NEC. The aforementioned use cases were demonstrated in a series of online workshops conducted by NEC using a Colfax-hosted learning cloud with NEC SX-Aurora TSUBASA / Vector Engine accelerators for students.

“The SX-Aurora TSUBASA Series or Vector Engine Accelerator provides users with the unique ability to perform high-performance computing and distributed data analysis at high bytes per flops,” said Akio Ikeda, deputy general manager of the AI ​​Platform Division of NEC Corporation, Japan. “The included compilers and libraries enable existing and new applications to be accelerated quickly and easily using famous or industry-standard AI / ML / DL frameworks in addition to conventional HPC applications.”
