This page provides information on working with shared CLEx storage resources at NCI.

NCI projects

The base unit for the accounting of computational and storage resources is the project, except for your home directory which has limited personal storage. There are 2 types of projects at NCI:

  • data projects: for published and shared datasets
  • computational projects: for running programs

To have a valid login at NCI, you need to be a member of at least one computational project.

This means when working on NCI machine, you will mainly work with shared resources. It is essential you learn how to use these resources fairly and efficiently.

CLEx projects

CLEx is managing several computational and data projects at NCI via the CMS team. We will not list the data projects since you do not have write access to any of those. To find datasets published at NCI, please see the information on this page

The computational projects are split by Research Program (RP):

Project RP Lead CI
v45 Extra-tropical variability Andy Hogg
w35 Drought Claire Carouge
w40 Extreme Rainfall Martin Jucker
w42 Extreme Rainfall Abhnil Prasad
w48 Tropical Variability Dietmar Dommenget
w97 Heatwaves Jason Evans

Some of the following information applies to all projects at NCI but keep in mind, this page focuses on the CLEx projects, as such some information might only apply to CLEx projects. See the Lead CIs of your other projects for information on those.

Accounting

NCI applies 2 types of quota on storage:

  • size
  • number of files

If a project exceeds one of these quota, all jobs from this project are put on hold until the storage is under quota again.

NCI and CMS provide a number of tools to check quota and help find the biggest users per project.

Tools for accounting

lquota


Description: an instantaneous view of usage and quota of all projects you are a member of for disk filesystems and of your home directory. Provided by NCI.

Output example:

$ lquota

ncimonitor


Description: time-series of computational and storage usage per user. Several options available. Provided by CMS.

Output example:

$module use /g/data/hh5/public/modules
$module load conda
$ncimonitor -P w35

nci_account -P <project>


Description: usage and quota information for the specific project required on all systems. Several options available. Provided by NCI.

Output example:

$nci_account -P w35
