Linux Shell (ssh) User Account Policies

Linux shell (ssh) accounts are assigned to users from the labs of NRSP-8 members for the following purposes:
  • Developing and maintaining of lab database and web sites
  • Performing computational genomics/genetics analysis
In principal, the following norms are observed on granting and the use of the user accounts:
  1. One user account will be granted per individual lab/ research group
  2. The PI of the lab/group assumes responsibility for proper use of the account
  3. Multiple users from a lab/group may share the use of the lab account, however, the names and contact information (email/phone) of each user must be filed with the system administrator. This is to insure that all users will receive system alerts in a timely mannaner.
  4. Disk space: A soft limit of about 10 GB of disk space will be placed on each account. If an account is expected to use more than 10 GB, users of the account should contact the system administrator immediately.
  5. All software installed on the system are on shared basis in general. Regular users are discouraged from installing new software. Should there be special needs for new software to install, the owner of the account must contact the system administrator for assistance.
  6. If you have intensive computing jobs to run, please check with the system admonistrator for shared CPU usage. The server types, limitations and capabilities of our servers are:
    • The dual processor Linux server: Our on-line web / database server. Jobs that take >90% of a CPU for more than 30 minutes should not be run on this server.
    • The 8-node CentOS Linux cluster: Our heavy-duty computing server. It can run intensive parallel jobs. (1) Parallel jobs must be submitted through MPI to queue; (2) Serial jobs must be allocated to run on a designated node; (3) Avoid using head-node to run your serial job.
    • The quad core Windows Server: To run Windows based applications. We do not have specific limitations on this computer as the use is currently light.
    Contact the system administrator if you are in doubt.
In case a user needs system support, please write email to the system administrator (bioinfo-team@animalgenome.org) with the following information: (1) detailed description of the operations that triggered an error; (2) copy of the error; and (3) names of the user account and the computer name.
