Mana is the 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. Mana is operated by UH Information Technology Service Cyberinfrastructure, that serves as a central university wide computational resource which supports data and computationally intensive research in over 90 disciplines. Mana consists of 366 nodes (9,396 cores) with a total of 67 TB of RAM, 120 GPUs and more than 1 PB of storage. Mana has grown steadily since it was deployed in late 2014, with investments from the University, an NSF MRI award ( #1920304 ) and ongoing Principal Investigator (PI) purchases of condo compute nodes. Mana 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 215 the University owned machines, but can also schedule work on the 130 PI owned nodes via partitions subject to preemption by node owners' job submissions.
Since 2014, over 685 users, across multiple campuses in the University system, have used Mana. Mana has also provided over 274,175,144 CPU hours since 2014 and 588,806 GPU hours since 2019. (last updated July 31, 2022)

Mana is FREE to use by all UH faculty, staff and students across the 10 campus system, but unlike UHUNIX, access to Mana is not granted by default to everyone at UH
Prerequisites to access and use Mana:
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 a Mana on-boarding session. Registration
Registered for and use DUO/MFA with your UH account. DUO/MFA Setup
