Aurora (Intel-HPE): Website

Aurora, Argonne’s first exascale computer, features Intel’s Data Center GPU Max Series GPUs and Intel XEON Max Series CPUs with HBM, a CPU-GPU interconnect (PCI-e), the HPE Slingshot fabric system interconnect, and a Cray EX platform. Aurora features several technological innovations and includes a revolutionary I/O system – the Distributed Asynchronous Object Store (DAOS) – to support new types of machine learning and data science workloads alongside traditional modeling and simulation workloads.   

The Aurora software stack includes the HPE HPCM software stack, the Intel oneAPI software development kit, and data and learning frameworks. Supported programming models include MPI, Intel OneAPI, OpenMP, SYCL/DPC++., Kokkos, RAJA, and others. HIP is supported via ChipStar/CHIP-SPV.

Frontier (Cray-HPE): Website

Frontier is a HPE Cray EX supercomputer located at the Oak Ridge Leadership Computing Facility. With a theoretical peak double-precision performance of approximately 2 exaflops (2 quintillion calculations per second), it is the fastest system in the world for a wide range of traditional computational science applications. The system has 77 Olympus rack HPE cabinets, each with 128 AMD compute nodes, and a total of 9,858 AMD compute nodes.  

Each Frontier compute node consists of a single 64-core AMD 3rd Gen EPYC CPU and 512 GB of DDR4 memory. Each node also contains [4x] AMD MI250X, each with 2 Graphics Compute Dies (GCDs) for a total of 8 GCDs per node. Each GCD has 64 GB of high-bandwidth memory (HBM2E) for a total of 512 GB of HBM memory per node.

Polaris (HPE): Website

Developed in collaboration with Hewlett Packard Enterprise (HPE), the 44-petaflop system called Polaris, is available to users through INCITE 2028 program. It was originally leaving INCITE after 2026, but it will now be in through 2028. Polaris is a hybrid CPU/GPU leading-edge testbed system that will give scientists and application developers a platform to test and optimize codes for Aurora, Argonne’s upcoming Intel-HPE exascale supercomputer. 

The Polaris software environment is equipped with the HPE Cray programming environment, PE Performance Cluster Manager (HPCM) system software, and the ability to test programming models, such as OpenMP and SYCL, that will be available on Aurora and the next generation of DOE’s high performance computing systems. Polaris users will also benefit from NVIDIA’s HPC software development kit, a suite of compilers, libraries, and tools for GPU code development.
