ExaNeSt project successfully builds prototype for exascale

Te consortium behind the EU-funded ExaNeSt project announced its first prototype of a new exascale computing system in September, with the prototype testbed system built successfully. Tey also stated the energy consumed for solving a given problem on this new platform is three to ten times lower than what traditional HPC processors of the same time generation consume to solve the same problem. Te prototype has been validated through

the execution of full HPC applications from materials science, climate forecasting, computational fluid dynamics, astrophysics and neuroscience. ExaNeSt aims to address key issues,

such as energy efficiency, by using ARM cores, moving data across shorter distances, and avoiding unneeded copying of data; it uses power-efficient and silent liquid cooling; the prototype has non-volatile memory integrated into the processor fabric,

combined with a fast interconnect, to avoid congestion. Te ExaNeSt consortium has 12

partners, each with expertise in a core technology needed for innovation to reach exascale. ExaNeSt has taken a sensible integrated approach to co-design the hardware and soſtware needed to enable the

prototype to run in real-life evaluations. ExaNeSt aims to contribute to a new

generation of European supercomputers, creating business opportunities. Te project’s advances in performance and efficiency will enable SMEs in several sectors to use HPC and data analytics, with an attractive trade- off between usability and affordability.
