Getting started on Quarry

Note: Following a system-wide upgrade in December 2012, Quarry now runs Red Hat Enterprise Linux version 6 (RHEL 6) and uses the Modules package (instead of SoftEnv) for manipulating user environments. For more, see Information about the 2012 upgrade to Quarry at IU. If you encounter any problems or have questions, email the High Performance Systems group.

Introduction

Quarry (quarry.uits.indiana.edu) is Indiana University's primary Linux cluster computing environment for research and research instruction use. It also serves as a "condominium cluster" environment for researchers, research labs, departments, and schools that want to have computational nodes housed within the IU Bloomington Data Center and managed by UITS Research Technologies staff. Additionally, Quarry provides a Virtual Machine hosting environment for the Extreme Science and Engineering Discovery Environment (XSEDE), the National Science Foundation's largest advanced cyberinfrastructure facility.

For system configuration details, plus information about requesting an account, logging in, compiling and running programs, and getting help, see Quarry at Indiana University.

Note: The maintenance window for Quarry is the first Tuesday of each month, 7am-7pm.

Getting started

• Accounts on Quarry are available to IU undergraduate and graduate students, faculty, and staff. To apply for an account, use the Account Management Service (AMS). For instructions:
  
  
  • If you already have IU computing accounts, see At IU, if I already have some computing accounts, how do I get others?
  • If you're new to IU and do not yet have computing accounts, see How do I get my first computing accounts at IU?
  • If you're not affiliated with IU, you'll need a faculty or staff sponsor; see About sponsored computing accounts for IU affiliates.
  
  
• If you already have a Quarry account and need help getting started, see Quarry at Indiana University.
  
  
• To learn more about home directories, CPU limits and batch jobs, and computational resources, read the Quarry usage policies.
  
  
• For information on changing your login shell and password, see At IU, on Quarry or Big Red, how do I change my login shell or passphrase?
  
  
• For information about disk space in home directories and scratch space, see At IU, how much disk space is available to me on the research systems?
  
  
• To learn how to use Modules to customize your software environment, see On IU's Mason and Quarry clusters, how do I use Modules to manage my software environment?
  
  
• View the list of software installed on Quarry.

Job management with Moab and TORQUE

On Quarry, Moab serves as the job scheduler for the TORQUE resource manager (also called PBS). For information about Moab and TORQUE, see:

• The "Moab at IU" section of What is Moab? in the IU Knowledge Base
  
  
• Common Moab scheduler commands in the IU Knowledge Base
  
  
• Using TORQUE/PBS on Quarry in the IU Knowledge Base
  
  
• The Cluster Resources TORQUE Admin Manual
  
  
• On Quarry, how do I run multiple MPI jobs using a TORQUE script? in the IU Knowledge Base

Getting help

Quarry is supported by the UITS High Performance Systems group. If you have system-specific questions about Quarry, email High Performance Systems. If you have questions about compilers, programming, scientific/numerical libraries, or debuggers, email Scientific Applications and Performance Tuning.

Additionally, announcements, downtime information, and further documentation are available on the Quarry cluster home page.
