The Arkansas High Performance Computing Center (AHPCC) provides expertise, high performance computing hardware, storage, support services, and training to enable computationally-intensive and data-intensive research. The AHPCC is available to faculty, staff and students at all of the Arkansas public universities, and to their collaborators inside and outside of the state. Most AHPCC services are provided free of charge to eligible researchers.

The Pinnacle I and II clusters from 2019 and 2022 are the newest resources at AHPCC. Pinnacle II consists of 71 AMD based nodes with a total of 74 NVidia Ampere class GPUs. Pinnacle I consists of 106 mostly Intel based nodes with a total of 26 NVidia Volta class GPUs. Total floating point capacity is more than one PetaFlops (one quadrillion floating point operations per second), mostly contributed by the GPUs. These systems are interconnected with an Infiniband network fabric at 100 Gb/s and connected to about 2.5 PetaBytes of high-speed storage and about 4 PetaBytes of nearline storage. These systems are connected at 100 Gb/s to the ARE-ON state and Internet2 national research networks and the UAMS HPC “Grace” system.(link under construction).

About 250 older machines are connected as the “Trestles” cluster and are used for less demanding tasks.

About 940 researchers have active accounts at AHPCC.

Use of the HPC is generally free of charge of Arkansas higher education researchers.
