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 ?#

HPC is used for long-running batch jobs that require intensive compute resources. Jobs can be monitored, but are not (usually) 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 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 HPC, such as MATLAB.
