Using Compute Canada's National Systems
How To Access
- You can SSH to the new servers using the following login nodes:
** Note: You will need to use your Compute Canada username and password to login (the same credentials you use for the CCDB). If you have troubles logging in or have forgotten your Compute Canada username or password, contact firstname.lastname@example.org.
- You can transfer files to and from the new systems using the Globus endpoints:
How To Use
The Compute Canada Documentation Wiki will be your go-to reference centre for step-by-step instructions and documentation for:
- Getting Started
- How to submit jobs
- Available software and modules
- Storage and filesystems
- Other How-To Guides
Getting Help & Reporting Issues
- Contact email@example.com to report issues, ask questions or share feedback on the new national systems.
- A national systems status page http://status.computecanada.ca/ is under construction.
Mini-Webinars - Intros to the Basics
A series of short webinars (5-10 minutes each) are available for quick and basic overviews of the new systems. These are meant to complement the Documentation Wiki pages, which are more detailed.
- Getting an account: If you don’t have a Compute Canada account, you’ll need to register for one to access these new national systems.
- General info: General information about the new national systems.
- Getting help: Need help? This short video will show you how and where to get it.
- Software environment: Learn more about the software environment of the national systems.
- File systems: Discover the ins and outs of the file systems on the new national systems.
- Managing jobs: Find out how to manage jobs on the new national systems, including basic slurm commands.
- Common mistakes to avoid: Save yourself time and discover the most common mistakes to avoid.
- Accessing the environment: This short video will tell you everything you need to know about accessing the new environment - from login to data transfer.
National System Training Archives
The following recordings of previously presented seminars may help you get started on the new systems:
- Cedar Demonstration (as part of WestGrid July Town Hall)
(recorded Wednesday, July 12)
Members of WestGrid's support team will provide a walk-through demonstration of using Cedar, including instructions for logging in, exploring the file systems, compiling basic programs, working with modules, running jobs via the SLURM scheduler, running interactive jobs, finding documentation and getting help.
- How Jobs are Scheduled to Run on Graham & Cedar
(recorded Wednesday, July 19)
This webinar describes the configuration of the new national systems' Slurm scheduler and how it determines how jobs are dispatched to resources. Beyond describing the scheduler configuration, this webinar will also provide recommended best practices when submitting jobs and demonstrate tools for monitoring jobs and the job queue on Graham and Cedar.
- What's New & Exciting About Graham's GPUs
On June 21, SHARCNET presented a webinar outlining the newest and largest SHARCNET cluster and Compute Canada national system, Graham. Among its exciting features is a substantial number (320) of the newest HPC GPUs from NVIDIA, Pascal P100. (The other new National Compute Canada cluster, Cedar, will have 584 Pascal P100 GPUs.) This will be a very significant improvement for SHARCNET users in terms of GPGPU capabilities, both quantitatively (27x more GPU flops than our older GPU cluster, monk) and qualitatively (new GPU capabilities; three generations newer than the monk GPUs). This webinar will discuss all the new important features of the Graham GPUs, with a live demonstration. Some minimum familiarity with GPGPU programming (CUDA or OpenCL) is desirable.
Migrating to the New Systems
If you are currently using a WestGrid system but would like to move your compute and data storage use to a national system, please refer to this General Directives for Migration page on the Documentation Wiki.
