Ookami is a computer technology testbed supported by the National Science Foundation under grant OAC 1927880. It provides researchers with access to the A64FX processor developed by Riken and Fujitsu for the Japanese path to exascale computing and is deployed in the, until June 2022, fastest computer in the world, Fugaku. It is the first such computer outside of Japan. By focusing on crucial architectural details, the ARM-based, multi-core, 512-bit SIMD-vector processor with ultrahigh-bandwidth memory promises to retain familiar and successful programming models while achieving very high performance for a wide range of applications. While being very power-efficient it supports a wide range of data types and enables both HPC and big data applications. The Ookami HPE (formerly Cray) Apollo 80 system has 176 A64FX compute nodes each with 32GB of high-bandwidth memory and a 512 Gbyte SSD. This amounts to about 1.5M node hours per year. A high-performance Lustre filesystem provides about 0.8 Pbyte storage. To facilitate users exploring current computer technologies and contrasting performance and programmability with the A64FX, Ookami also includes: - 1 node with dual socket AMD Milan (64cores) with 512 Gbyte memory - 2 nodes with dual socket Thunder X2 (64 cores) each with 256 Gbyte memory - 1 node with dual socket Intel Skylake (32 cores) with 192 Gbyte memory and 2 NVIDIA V100 GPUs

The NCSA Delta CPU allocation type provides access to the Delta CPU-only nodes. The Delta CPU resource comprises 124 dual-socket compute nodes for general purpose computation across a broad range of domains able to benefit from the scalar and multi-core performance provided by the CPUs, such as appropriately scaled weather and climate, hydrodynamics, astrophysics, and engineering modeling and simulation, and other domains using algorithms not yet adapted for the GPU. Each Delta CPU node is configured with 2 AMD EPYC 7763 (“Milan”) processors with 64-cores/socket (128-cores/node) at 2.55GHz and 256GB of DDR4-3200 RAM. An 800GB, NVMe solid-state disk is available for use as local scratch space during job execution. All Delta CPU compute nodes are interconnected to each other and to the Delta storage resource by a 100 Gb/sec HPE Slingshot network fabric.

The Delta GPU resource comprises 4 different node configurations intended to support accelerated computation across a broad range of domains such as soft-matter physics, molecular dynamics, replica-exchange molecular dynamics, machine learning, deep learning, natural language processing, textual analysis, visualization, ray tracing, and accelerated analysis of very large in-memory datasets. Delta is designed to support the transition of applications from CPU-only to using the GPU or hybrid CPU-GPU models. Delta GPU resource capacity is predominately provided by 200 single-socket nodes, each configured with 1 AMD EPYC 7763 (“Milan”) processor with 64-cores/socket (64-cores/node) at 2.45GHz and 256GB of DDR4-3200 RAM. Half of these single-socket GPU nodes (100 nodes) are configured with 4 NVIDIA A100 GPUs with 40GB HBM2 RAM and NVLink (400 total A100 GPUs); the remaining half (100 nodes) are configured with 4 NVIDIA A40 GPUs with 48GB GDDR6 RAM and PCIe 4.0 (400 total A40 GPUs). Rounding out the GPU resource is 6 additional large-memory, “dense” GPU nodes, containing 8 GPUs each, in a dual-socket CPU configuration (128-cores per node) and 2TB of DDR4-3200 RAM but otherwise configured similarly to the single-socket GPU nodes.

All Delta GPU compute nodes are interconnected to each other and to the Delta storage resource by a 100 Gb/sec HPE Slingshot network fabric.
A Delta GPU allocation grants access to all types of Delta GPU nodes (both GPUs and CPUs on those nodes). The Delta CPU allocation is needed to utilize the CPU-only nodes.

The Delta Storage resource provides storage allocations on the scratch file system for projects using the Delta CPU and Delta GPU resources. It delivers 4PB of capacity to projects on Delta and will be augmented by a later expansion of 3PB of flash capacity for high-speed, data-intensive workloads. Projects are provided with a 1TB allocation on scratch by default. Please do not request storage allocations smaller than 1TB.

Anton is a special purpose supercomputer for biomolecular simulation designed and constructed by D. E. Shaw Research (DESRES). PSC's current system is known as Anton 2 and is a successor to the original Anton 1 machine hosted here. Anton 2, the next-generation Anton supercomputer, is a 128 node system, made available without cost by DESRES for non-commercial research use by US universities and other not-for-profit institutions, and is hosted by PSC with support from the NIH National Institute of General Medical Sciences. It replaced the original Anton 1 system in the fall of 2016.

Anton was designed to dramatically increase the speed of molecular dynamics (MD) simulations compared with the previous state of the art, allowing biomedical researchers to understand the motions and interactions of proteins and other biologically important molecules over much longer time periods than was previously accessible to computational study. The MD research community is using the Anton 2 machine at PSC to investigate important biological phenomena that due to their intrinsically long time scales have been outside the reach of even the most powerful general-purpose scientific computers. Application areas include biomolecular energy transformation, ion channel selectivity and gating, drug interactions with proteins and nucleic acids, protein folding and protein-membrane signaling.
