论文摘要
SX-AURORA TSUBASA PCIE ACCELERATOR卡是NEC SX Architecture家族的最新型号。其多核矢量处理器的矢量长度为16 kbit和接口，在当前型号中具有高达48 GB的HBM2存储器，自2018年以来可用。计算性能高达2.45 tflop/s的双重精度，并且内存吞吐量高达1.2 tb/s。在不久的将来宣布具有改进性能特征的新模型。在此贡献中，我们讨论了SX-Aurora的关键方面，并描述了我们如何在网格晶格QCD框架中启用体系结构。
The SX-Aurora TSUBASA PCIe accelerator card is the newest model of NEC's SX architecture family. Its multi-core vector processor features a vector length of 16 kbits and interfaces with up to 48 GB of HBM2 memory in the current models, available since 2018. The compute performance is up to 2.45 TFlop/s peak in double precision, and the memory throughput is up to 1.2 TB/s peak. New models with improved performance characteristics are announced for the near future. In this contribution we discuss key aspects of the SX-Aurora and describe how we enabled the architecture in the Grid Lattice QCD framework.
