At Instituto de Astrofísica de Canarias (IAC)

The supercomputer LaPalma has 252 computing nodes, providing a maximum performance of 83 TFlops. The data node has a capacity of 600 TB, accessible at 10 Gbps. Both the supercomputer LaPalma and the data node are located at the Astrophysics Centre in La Palma, one of the four sites of the IAC.

The IAC, recognized by the Spanish government as a "Severo Ochoa Centre of Excellence", is a nationally funded research centre that runs the Observatories of the Canary Islands, two of the largest international observatories in the world, in Tenerife and La Palma.  The IAC is a Public Consortium constituted by the General Administration of the Spanish State, the Public Administration of the Autonomous Community of the Canary Islands, the University of La Laguna (ULL), and Spain's Science Research Council (CSIC).
