Home

  • Home directory is where you log in to.
  • Home directory quota is limited, it is not advisable to put analysis data here. Please use /data/users*/< your directory > instead.
  • You can ls ~ from anywhere to quickly switch to the home directory. pwd will show full path to the current location.

Users /data/users1 and /data/users2

TReNDS center members own and can keep their data in /data/users/2 directory.

The user storage is limited and shared between all members of the lab. So please make sure to clean up your user directory in /data/users*/< username > periodically and remove any data that are either duplicate (available at another location on the cluster) or no longer needed.

Use df -h command to have a look at the overall storage capacity of the cluster. You can use du options such as du -h --max-depth=1 | sort to get more detail information.

Use dust to get a visual description of what’s inside a directory. Make sure /trdapps/linux-x86_64/bin/ is in your path to have the command working.

Mialab /data/mialab2, Analysis /data/analysis & Collaboration /data/collaboration

MIALab, collaboration and auto-analysis data are stored here.

Neuromark /data/qneuromark and /data/neuromark2

Neuromark datasets are located here. Qumulo storage (/data/qneuromark) capacity, usage, quota etc. can be viewed at trendsq1.gsu.edu.

/trdapps

Some specific software (which are not available as modules, such as GIFT) are installed in /trdapps. Add /trdapps/linux-x86_64/bin/ to your path to take advantage of these tools:

export PATH=/trdapps/linux-x86_64/bin/:$PATH

/scratch

This is for short-term data, great for working environment such as moving files during a job, storing data to be used in a job, or storing generated files from a job. Transfer output and resulting data off /scratch after job is executed.

/raid

It is a local SSD on the DGX machines for fast data transfer.

/dev/shm

You can directly load data on to memory by using /dev/shm for very fast processing. It is recommended to reserve a full node when using /dev/shm and take special precautions to prevent out-of-memory errors.

Be very careful when using /dev/shm because overloading this may destroy the node.
