The NTI has access to several ORNL cluster systems in support of the capacity-level computing needs of CNMS users. The workflow on these systems is focused on timely turnover for development and delivery of new science.
The Compute and Data Environment for Science (CADES) at ORNL is s a Cray CS400 cluster (CADES condo) with 32-36 core Haswell/Broadwell Based nodes as well as a baseline cluster of 128 core AMD 7713 nodes (CADES baseline) to perform scientific computations and run simulation codes.
Frontier Computational Cluster (OLCF)
Frontier is based on HPE Cray’s new EX architecture and slingshot interconnect with optimized 3rd Gen AMD EPYC CPUs for HPC and AI, and AMD Instinct 250X accelerators.
Perlmutter Computational Cluster (NERSC)
Perlmutter, based on the HPE Cray Shasta platform, is a heterogeneous system comprised of 3,072 CPU-only and 1,792 GPU-accelerated nodes. Perlmutter is a HPE (Hewlett Packard Enterprise) Cray EX supercomputer.
