Overview

At MCB, SBGrid provides a comprehensive system administration support for all Linux computers. Supported labs include the Gaudet and D’souza labs. All computers are located on a virtual local area network supported by Harvard research computing on the Cambridge campus To reach this network from an external location please ssh to galactica.mcb.harvard.edu, and access your local resources from there.

To request support please contact help@sbgrid.org. For support with software installation please email bugs@sbgrid.org. New members joining the lab should contact help@sbgrid.org as well to complete the initial setup.

Computers

Setup on Linux Computers

The Linux computers share authentication and data directories and can be only accessed locally from within the lab. Home directories are located at /labdata/<lab initials>/<username> (example: /labdata/vdg/testname). A comprehensive collections of SBGrid applications is located at the /programs directory. Some systems are configured with Stereo 3D. Pioneer contains a license for running HKL2000.

In addition, cerberus which is a 64 cores 2 node computer cluster running OpenLava can be accessed remotely and is typically used for docking computations and data processing. To access it, ssh to galactica.mcb.harvard.edu

Please note that your home directories are only visible to your labmates and PI by default. Permissions vary depending on the nature of the directory or files in questions. PI’s should discuss file permissions with SBGrid to suit their needs.

Printing

There are 2 printers available. One located in the hallway near room 305 (carmen) and one in the wet lab area (vger). If you have issues with the printers, please contact help@sbgrid.org.

Data Backups

Snapshots are taken every hour and kept for 24 hours on the file server. Additionally, 7 daily snapshots are kept, 8 weeks, and up to 12 months. Data is also replicated to a secondary server. If you need a file restored, please contact help@sbgrid.org.

Networking and General IT Support

To report problems regarding the network at Harvard University, or general computing support, contact the Harvard University Help desk. If you need to activate a port in the lab for a new SBGrid system, please contact Harvard research computing and copy SBGrid.
