MML is happy to announce the availability (currently in private preview) of our R6 cluster for scientific computing to research groups and individual researchers. Access to R6 does not require a project proposal.
R6 is optimized for memory bandwidth-driven applications, such as density functional theory, molecular dynamics, fluid dynamics, and finite element analysis. Each R6 virtual machine (VM) features 120 AMD EPYC 7742 processor cores, 4 GB of RAM per CPU core with no simultaneous multithreading, providing up to 350 GB/s of memory bandwidth and FP64 compute of up to 4 teraflops. R6 VM interconnects are based on 200 Gb/sec Mellanox HDR InfiniBand, in a non-blocking fat tree for optimized RDMA performance, supporting Adaptive Routing and Dynamic Connected Transport. Each R6 server can utilize up to 100 VMs or 12,000 CPU cores on Linux SLURM. The total R6 capacity is currently 120,000 CPU cores.
