Thereby, Adastra will be based on a balanced and modular converged architecture with 2 complementary compute partitions, to answer the various needs of hundreds of daily users:
- Partition 1 has manycore scalar nodes, each one based on next-generation AMD EPYC processors, codenamed “Genoa” with 768 GB of DDR5 memory and one 200 Gbps Slingshot 11 NIC
- Partition 2 has hybrid nodes, each one with an optimized 3rd Gen AMD EPYC CPU with 256GB of DDR4 memory and four AMD Instinct MI250X OAM accelerators, each with 128 GB HBM2e, for a total of 512 GB GPU memory, and four 200 Gbps Slingshot 11 NICs
The accelerated partition (GPU) is scheduled to be commissioned in the spring of 2022 while the scalar (CPU) partition is planned to be commissioned end of 2022.
The whole system, federated by HPE Slingshot, a high-performance Ethernet fabric designed for HPC and AI solutions, will access a two-level Cray ClusterStor E1000 Lustre parallel file system from HPE providing close to 2PB with a throughput of 1.3 TB/s based on the level 1 full-flash scratch and a second level based on 24 PB @ 250 GB/s based on fast rotative disks.
