The supercomputer is built on the Bull Sequana X architecture and for cooling its standard compute nodes the direct liquid cooling technology is used. The computing network is built on the latest Infiniband HDR technology. The SCRATCH computing data storage capacity is 310 TB with 28 GB/s throughput using Burst Buffer acceleration. Another computing data storage is NVMe over Fabric with a total capacity of 22.4 TB dynamically allocated to compute nodes. It is also equipped with the Bull Super Computer Suite cluster operation and management software solution as well as PBS PRO scheduler and resource manager. The computing network is built with the latest Infiniband HDR technology.
