Supercomputation

PROTEUS is the main service that the Instituto Interuniversitario Andaluz Carlos I de Física Teórica y Computacional (iC1) offers to its members and collaborators. It provides an HPC (High Performance Computing) environment that incorporates the latest trends in computing and is optimised for scientific calculations and simulations. It consists of a cluster of high-performance nodes with cloud computing and cloud storage capabilities.

Together with Alhambra, supercomputer of the University of Granada, it places the University of Granada in a prominent position in Spanish scientific supercomputing.

Applications and Resources

_

PROTEUS is managed by free GNU / Linux software. Its architecture is of the Beowulf type, (implemented for the first time by NASA and widely used, among others, by Google itself), whose main advantage is that with a very tight budget, great computing power can be obtained while its maintenance is little expensive.

The previous version of PROTEUS had been overwhelmed by its intensive use, as scientists have been using its resources one hundred percent since it was inaugurated in 2008.

This success of use is attributable to the PROTEUS management policy, which does not establish a time limit on the execution of the processes (some of them run for six months), nor are memory or disk usage quotas assigned. hard, but there is an automated manager (Condor) that, in case of saturation, privileges the user who has used the least calculation time up to that moment.
