High-Performance Computing Resources

Discovery 

Discovery is a 2200 processor Linux RedHat 6.5 cluster that is available to the Dartmouth research community. The discovery support team provides consulting on debugging, optimizing and parallelizing code and will install additional application software if requested.

Andes

Andes is a shared memory computer (SMP) with 12 cores (24 threads), 64-bit Intel processors, and 96 GB of memory.  It runs Red Hat Enterprise Linux 5 and is mostly used to run statistical packages and scientific applications which need large amounts of memory and scratch space.  2.8 TB of fast scratch space is available.  Authentication uses RStor usernames and passwords, and home directories are in RStor (shared with other systems). Accounts are available to all faculty, staff and graduate students, plus sponsored accounts on request.  Access is by SSH (remote login) from on-campus only.

  • More information about Andes and Polaris environments
  • Requests to install additional application software are welcome and should be directed to Research.Computing@dartmouth.edu

Polaris

Polaris is a shared memory computer (SMP) with 40 cores, 64-bit Intel processors, and 1 Terabyte of memory, running Red Hat Enterprise Linux 6.5. It is used to run computationally intensive such as mathematica and statistical applications.  It can be used to run programs that require a lot of  shared memory. It has 5 TB of local scratch space available.  Authentication uses RStor usernames and passwords, and home directories are in RStor. Accounts are available to all faculty, staff and students, plus sponsored accounts on request. Access is by SSH (remote login) from on-campus only.

Caligari Web and Database Server

Caligari is a web server which delivers pages directly from Dartmouth's AFS cell (RStor) and augments the Research Computing home pages. It can be used for delivering home pages from AFS accounts, available to all members of the Dartmouth Community. It is also used to deliver the web-based documentation which accompanies many software packages used on our central Research Computing systems.  It runs Apache on Red Hat Enterprise Linux, with PHP5, WebAuth and SSL available.  MySQL is available to select projects.  All AFS (Rstor) accounts are automatically enabled on Caligari.  Explicit login to Caligari is not required or permitted.

Faculty Workstation Support

To facilitate faculty members' curricular and research work, Research Computing offers support in the administration and management of de-centralized UNIX workstations.

This support includes consulting, training, and system administration. System administration assistance is provided on an on-call basis. If you are a faculty member and you have questions on any aspect of support for faculty workstations, please contact Research.Computing@dartmouth.edu.

Off-campus access

Andes and Polaris permit direct login from off-campus, but they are protected by an additional security feature that will block clients trying to connect with invalid usernames, or which fail the password check too many times.

Off-campus access may also be achieved via VPN, or by logging in first to sshlogin.dartmouth.edu.  This system is provided as an alternative to the VPN, and can only be used for SSH (secure command line access) to campus resources.  Accounts  on sshlogin are available to all members of the Dartmouth Community, plus sponsored accounts by arrangement, anc can be requested by emailing Research Computing
