Taking advantage of technology innovations in the next generation of NeSI HPC infrastructure
presentationposted on 26.02.2021, 00:05 by Jeff Zais
ABSTRACT / INTRODUCTION
NeSI, the New Zealand eScience Infrastructure, provides HPC access for users throughout New Zealand. The primary systems are Mahuika and Maui, Cray clusters based on Intel “Broadwell” and “Skylake” processors, respectively. NeSI regularly updates capabilities through the addition of both specialized nodes and expansion of clusters. Usage on both Maui and Mahuika has steadily grown since they were introduced in 2018, and added capacity is required to handle future user demand. This talk will review that usage, plus the options evaluated for an expected 2021 addition to Mahuika. In particular, HPC technology advances in processors, system interconnect, and memory technology will be surveyed. By combining these innovations, an expansion of Mahuika will be summarized, which should serve to enable research for the New Zealand scientific community in the next years.
