Computers

SBGrid supports Linux, Mac, and Windows computers in the Harrison & Chou labs.

Linux

Most Linux computers use network accounts, meaning that your home directory is located on a network storage server and is backed up. If you accidentally delete important files, please let us know as soon as possible and we may be able to restore the file for you.

Linux systems have network home directories and access to the SBGrid programs tree (via /programs). See this link for information on how to access the software.

Mac

Mac computers rely on either network accounts or local accounts. We will soon transition all Mac computers to local accounts because of problems many people have encountered Macs & network accounts.

For Macs with local accounts, users will have administrative access with permission to install and update software. The SBGrid Installer will be used to access the SBGid software tree and will allow users to install and update the software independently. These computers are backed up via Crashplan, hosted by HMS. If your Mac is not backed up, or you receive warning messages about Crashplan backup failures, please contact us immediately to ensure that no data is lost.

Windows

Windows computers used to run instruments in the labs should not be used for browsing the Web. If you encounter any problems with these machines, please contact SBGrid as soon as possible. If SBGrid is unavailable, please contact HMS-IT, with details about your problem and the buiding and floor where where the machine is located. Be sure to notify SBGrid that you have contacted HMS-IT so that we can liaise with them.

Data Collection Machine

There is a Mac Mini named bcmp-remotedata-macmini for use when collecting data from beamlines.

Harrison Lab members can share data via this Network directory: /nfs/userdocs/sch/COMMON

Chou Lab members can share data via this Network directory: /nfs/userdocs/jc/COMMON

EM Facility

To access the EM Facility in the basement of SGM, please contact Zongi Li or Melissa Chambers.

If you need a data directory created on the EM systems, please email SBGrid and cc Zongi Li. Please remember that data directories on the EM systems are not backed up. It is essential that you store your data elsewhere.
