Koa
Â
Koa came online June of 2023. It is the second University of Hawai‘i (UH) high performance computing (HPC) cluster – a collection of many computers called nodes connected together with a network –  that solves computational problems too large for standard computers. Koa is operated by UH Information Technology Service Cyberinfrastructure, which serves as a central university-wide computational resource that supports data and computationally intensive research in over 90 disciplines. Koa consists of 263 nodes (7219 cores) with a total of 52 TB of RAM, 146 GPUs and more than 6 PB of storage. Koa is a continuation of Mana containing equipment deployed in late 2014, with investments from the University, an NSF MRI award ( #1920304) in 2019, two CC* awards (#2201428 and #2232862) in 2022 and 2023, and ongoing Principal Investigator (PI) purchases of condo compute nodes. Koa is free to use for all UH users, with the Slurm Workload Manager managing access with a fair share algorithm. UH community users get uninterrupted access to the all university-owned machines, but can also schedule work on the PI-owned nodes via partitions subject to preemption by node owners' job submissions.
Â
Koa is FREE to use by all UH faculty, staff and students across the 10-campus system, but unlike UHUNIX, access is not granted by default to everyone at UH.
Prerequisites to access and use Koa:
Be an active UH faculty, staff or students affiliated with at least one of the 10 campuses in the UH system
Sign up for and attend an onboarding session. Â Registration
SSH client or web browser
Koa’s hostname: koa.its.hawaii.edu
