High Performance Computing (HPC) Cluster

Service Initiation

Researchers who are interested in participating in the shared HPC cluster should contact the HPC goverance committee through Rajendra Bose, RCS Manager (rbose@columbia.edu).

Priority definitions

Priority can be deduced using a combination of Urgency and Impact. For reference, the definitions of these terms are as follows:

Impact:a measure of the business criticality of an Incident, often equal to the extent to which an incident leads to degradation of agreed service levels. Impact is often measured by the number of people or systems affected.

Urgency:the necessary speed of solving an incident of a certain impact. A high-impact incident does not, by default, have to be solved immediately.

Priority:is expected effort. This is denoted by a number value, and is determined through assessing a combination of impact and urgency.

The matrix below describes the framework for determining priority.

PRIORITY
		Impact
		Impact
		High	Medium	Low
Urgency	High	1	1	2
	Medium	2	2	3
	Low	2	3	3

Service Description

CUIT manages a shared high performance computing (HPC) cluster for researchers in participating departments.

Status:

Active

Details

CUIT manages a shared high performance computing (HPC) cluster (named Hotfoot) for researchers in the departments of Astronomy & Astrophysics, Statistics, and Economics plus other groups represented in the Social Science Computing Committee (SSCC).

Standard Service Features

For this service, multiple CUIT groups, in partnership with an HPC governance committee, help to design the system architecture, purchase hardware with service contracts (using researcher-provided funds), and manage and provide support for the cluster. The Research Computing Services (RCS) team provides user support, manages the HPC scheduling software, and coordinates interaction with the governance committee.

Service Eligibility

Select researchers in the departments of Astronomy & Astrophysics, Statistics, Economics and other groups represented in the Social Science Computing Committee (SSCC) are eligible to use the system. Information about eligibility and accounts can be requested from the HPC governance committee through Rajendra Bose, RCS Manager (rbose@columbia.edu).
