Welcome to the Centrale Nantes Supercomputing Center (CNSC) managed by the ICI tech staff team. We are happy to assist you in getting started with your new account. We offer documentation on our website, new user training, seminars, as well as many other services.
A legitimate need for supercomputing resources ? The High Performance Computing Cluster at ICI is a collection of servers designed to process long-running, compute-intensive batch jobs. The cluster consists of a large number of compute nodes connected by a high performance Infinband network and high throughput storage (GPFS). You can find more answers here:
The HPC is used for long-running batch jobs that require intensive compute resources. Jobs can be monitored, but are not interactive. Compute jobs running in the HPC can operate in parallel using popular frameworks like OpenMP and MPI.
Many users write and/or compile their own software to run on the HPC, for which we provide a number of tools and libraries to support. Other users can run jobs in general purpose applications, already compiled and installed on the HPC, such as MATLAB.
A supercomputer account provides access to all computational resources. Before gaining access you will need the following to be understood:
A secure shell client (SSH, various versions available for free)
Print this cheat sheet and stick it by your computer while you're getting started with LIGER.
If you want to learn how to use the text editor vim (or vi), please run
vimtutor after connecting to our systems via ssh on login nodes.
Please check the top right of the website for notices and alerts. Notices include notification of system maintenance, downtime, and other announcements. Emails are also sent for important announcements.

In general, your account will generally be set to expire one year from the time you requested it. You will receive an email reminder to renew your account one month before the expiration date.
If you're not sure what programming language to use, try Julia. Julia is easy to use, designed for scientific computing, and is almost as fast as C.
