Research Computing: Quick Reference

ACL

  • An access-control list, with respect to a computer file system, is a list of permissions attached to an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in a typical ACL specifies a subject and an operation.

ARCC

  • Advanced Research Computing Center

Bash

  • Bourne-Again Shell (See #Shell)

CIFS

  • Common Internet File System (See #SMB)

Cloud Computing

  • Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet.

Cloud Storage

  • Cloud storage is a service model in which data is transmitted and stored on remote storage systems, where it is maintained, managed, backed up and made available to users over a network (typically the internet). Users generally pay for their cloud data storage on a per-consumption, monthly rate.

Csh

FTP

  • File Transfer Protocol

Globus

  • A data transfer and sharing framework built around the use of the GridFTP protocol

GPFS (See IBM Spectrum Scale)

  • General Parallel File System

GridFTP

  • A protocol that extends FTP to be suitable for high performance/large data transfer; has multiple implementations including by Globus (See #FTP#Globus)

HPC

  • High-Performance Computing

HTC

  • High Throughput Computing

Mount Moran

  • The first UW centralized condominium cluster installed in 2012.

NFS

  • Network File System (NFS) is a client/server system that allows users to access files across a network and treat them as if they reside on the local computer.

NSF

  • National Science Foundation

NWSC

  • NCAR-Wyoming Supercomputing Center

petaLibrary

  • Capacity-designed storage system to share data with other members of UW and external institutions.

Research Computing

  • The use of computing infrastructure, local or centralized, to perform research or aid experimental or theoretical research.

RMACC

  • Rocky Mountain Advanced Computing Consortium

Science DMZ

  • A Science Demilitarized Zone (DMZ) is a portion of a larger network that has been configured and optimized for the transfer of high-volume scientific data.

Shell

  • Command-line interface or shell that provides a traditional Unix-like command-line user interface to the operating system.

Slurm Workload Manager

  • A flexible and scalable scheduler that implements job scheduling, fairshare, limits, and Quality of Service (QoS)

SMB

  • Protocol for accessing remote filesystems on a Windows or Linux/Unix based operating system.

SSH

  • Secure SHell

Teton

  • 2018 ARCC Intel-based HPC Cluster

XSEDE

  • Extreme Science and Engineering Discovery Environment
