Cloud Computing with SURFsara's Cartesius Cluster

SURFsara’s Cartesius Cluster: Overview

Cartesius is a supercomputer in the true sense of the word. All servers in the cluster are linked with high-speed connections to form a very large computer. Cartesius is best suited for calculations in which the individual components (functions and procedures) have a great interdependence. A so-called Graphical Processing Unit (GPU) is also offered in this environment. In some cases, for example with Floating Point calculations, running a program on a Graphics adapter is much more efficient than on a computer processor.


  • The most rapid solution.
  • Graphical Processing Unit (GPU) available.
  • A huge amount of software.
  • Users do not have to share resources but have exclusive access.


  • Steep learning curve. Knowledge is required to be able to build an efficient job.
  • No direct access to the joint network of Tilburg University.
  • There may be a queue and thus waiting time.
  • Less interactive because of the queue principle.
