PICSL-cluster Transition Guide

welcome to the CfN cluster. This document will be filled out shortly with more details.

Here is some info regarding your transition to the CfN cluster:

Usernames and Passwords

Your username should be the same as on the PICSL cluster.

Your password: if you already had a CfN cluster account, your password will be the one associated with that account. If you didn't previously have a CfN account, your password should be the same as when you logged onto the PICSL cluster.

Home Directories

Your PICSL /home dir is now in /data/picsl/your-username

When you login to CfN cluster you have a new /home dir.

Your CfN /home dir is NOT a data directory. It has a 25GB quota. Please put your data in /data/picsl.

You may want to couple settings/configuration files from your old home dir (now in /data/picsl) to your new home directory. Note that most of these will be 'dot-files' that start with a period. To view them, use the -a option to ls:

ls -a ~

Data Drives

The data directories have been moved to provide consistent naming on the CfN cluster.

PICSL Path       CfN Path
/home            /data/picsl
/mnt/data        /data/tesla-data
/mnt/home        /data/tesla-home
/mnt/build       /data/picsl-build (not yet working properly)
/data/grossman   /data/grossman

You'll have to update your scripts. Sorry for the trouble.

Applications

The common/shared applications from the PICSL cluster are now in /data/picsl/local (i.e. the ones that were in /home/local).

The CfN cluster stores common/shared applications in /share/apps. Most of these have been added to your search path in your $HOME/.bash_profile file.

Quotas

Quotas on the CfN cluster (/home, /data/jet, /data/jag) are handled on a per-project basis, meaning quotas are set for individual data directories like /data/jag/mgstauff. The quota applies to all files in the directory and its sub-directories, regardless of owner.

This differs from the PICSL cluster data quotas, which are per-user. For now, quotas for the PICSL drives (/data/picsl, /data/tesla-data, /data/tesla-home) will remain unchanged, and per-user. At some point we'll merge these into per-project quotas for better management.

You may have symlinks in your PICSL data/home directories. These will need to be changed.

To find all symlinks in a directory and its sub-directories and print out the file it links to, use this command:

find directory-to-search -type l -print0 -exec echo -n " " \; -exec readlink -m {} \;
