II. High Performance Computing facilities
A computer can be a workstation (desktop or laptop) or a high performance computing (HPC) facility. HPC gives you far more computing power, but comes with a price: you may have to adjust your scripts and must learn how to operate such a system. HPC computers don’t have a nice interactive, graphical user interface. Scripts must be submitted and scheduled via the command line. On an average workstation, parallelisation is limited to 2 or 3 threads or cores. On HPC you can use up to thousands. HPC also provides special computing devices (GPU) and larger memory (64GB+). Even if you don’t run your computations in parallel, you can use HPC to free up your workstation for other tasks.
Two HPC facilities are available for researchers of Utrecht University:
On these systems the most used software tools are pre-installed, but it is also allowed to install your own software provide they are suited to run on the system and you have the appropriate license.
You can contact RDM Support for assistance to use the HPC facilities.
