Performance Evaluation of SX-Aurora TSUBASA by Using Benchmark Programs bandwidth, which is one of the features of SX-Aurora TSUBASA, is evaluated by using the Stream benchmark. Next, the performances of the Himeno benchmark and the HPCG benchmark are examined. From these evaluations, it is clarified that the high sustained memory bandwidth can be achieved. It is also

VEO and PyVEO: Vector Engine Offloading for the NEC SX-Aurora Tsubasarge HBM2 memory of 48 GB and high memory bandwidth of 1.2 TB/s. It is completely different from the previous mainframe-sized product generations and comes as a PCIe card pluggable into normal Linux servers, where the VE integrates seamlessly into the Linux environment and runs native VE programs com

Bad Nodes Considered Harmful: How to Find and Fix the Problemincreasing chance of failure of any component in the system, necessitating research as how to cope with failure. Failures may manifest as compute nodes shutting down, but also in differing performance among compute nodes. This chapter concerns itself with investigating a recent occurrence of the lat
