Welcome to Geryon2 and Geryon3

Geryon 2 and Geryon 3 are two computer cluster dedicated to astrophysical calculations for the Chilean astronomical community, located at the Instituto de Astrofísica and management shared with the Centro de Astro-Ingeniería, in the Pontificia Universidad Católica de Chile. The cluster is part of CATA facilities.

The supercomputer Geryon 2 is made up of 20 nodes. Fourteen of these nodes have 40 cores and 320 Gb memory each, one node has 32 cores and 512 Gb memory, and the remaining five nodes have 56 cores and 512 Gb memory. In total, Geryon 2 has 872 cores and 8.28 Tb of memory.

On the other hand, the new cluster Geryon 3 is composed of 12 nodes, each with 64 cores and 512Gb memory, providing a total of 768 cores and 6.14 Tb of memory.

Nodes are running on Centos Linux system. Storage capacity involves around 1 Pb SAS, 38 Tb fast-SAS and 380 Tb standard SATA disks.

Additionally, we have two units equipped with Tesla GPUs featuring 3072 Cores and a combined memory capacity of 200 GB RAM.

Development and execution tools include Intel compilers (ifort, icc), and GNU compilers (gcc, g++, gfortran, etc). Parallel support for OpenMPI, mpich2, OpenMP, and scientific parallel optimized libraries(fftw,gsl,hdf5,atlas). Python support with typical scientific libraries. Job scheduling is controlled by Maui Cluster Scheduler and Distributed Resource Management (DRM) software (TORQUE).
