Pierre-Emmanuel GuerinWelcome 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.
What is HPC?
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:

What is it used for ?
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.
The Basics
A supercomputer account provides access to all computational resources. Before gaining access you will need the following to be understood:
Secure Shell
A secure shell client (SSH, various versions available for free)
- Linux/Mac Users
-
Windows Users; Windows does not have SSH capabilities built-in. Download one of these tools
- PowerShell Terminal witth SSH command (only for Windows 10)
- PuTTY
- Bitvise Tunnelier
- MobaXterm
