Prospero specifications

Prospero’s is based primarily on HPE Apollo (Gen 10) systems. The main computing partition is built from Apollo 2000 shared infrastructure chassis, each of which hosts four compute nodes. The GPU accelerated partition comprises a single Apollo 6500 chassis, hosting a single server with four GPU engines.

Standard compute node specification:

  • HPE ProLiant XL225n Gen10+ server

  • 2x AMD EPYC 32-core processors (7502 2.5GHz in 36 nodes, 7513 2.6GHz in 16 nodes)

  • 512GB DDR4-3200 memory

  • 480GB SATA SSD local storage

  • HDR100 Infiniband network interface

Whole cluster performance of 52 nodes was 84.7 Tflops.

  • Single node performance of 1.9 Tflops for the EPYC2 nodes.

  • Single node performance of 1.75 Tflops for the EPYC3 nodes.
