Introduction to the Wisteria/BDEC-01
Characteristics of the system
The Wisteria/BDEC-01 is a supercomputer system operated by the Information Technology Center, The University of Tokyo. Wisteria/BDEC-01 is a hybrid system including two groups of compute nodes: Simulation Nodes (Odyssey) and Data/Learning Nodes (Aquarius). Simulation nodes group (Odyssey) is consists of 7,680 compute nodes equipped with Fujitsu Limited's FUJITSU Processor A64FX, same CPU as the world's most powerful supercomputer, Fugaku. Data/Learning nodes group (Aquarius) consists of 45 compute nodes with Intel 3rd Generation Xeon Scalable Processors (code name: Ice Lake) and NVIDIA A100 Tensor Core GPUs.
