The ALTAMIRA Supercomputer

The ALTAMIRA node of the RES at the University of Cantabria is located in the Juan Jorda Building and is jointly managed by the IFCA Distributed Computing Team and the Computer Architecture Group (ATC) of the University of Cantabria.

IFCA (Instituto de Física de Cantabria) is a joint centre of the University of Cantabria and CSIC with research lines in astrophysics, high energy physics and distributed computing. It participates in several national and European computing projects.

The main research areas of the Computer Architecture Group (ATC) of the University of Cantabria are the analysis, design, and evaluation of parallel computers, covering their principal aspects from programming to the lower hardware levels.

The ALTAMIRA node was upgraded in June 2012 with the installation of a new system at IFCA datacenter room and became fully operational in October 2012. The current systems in the ALTAMIRA node is composed of 158 IBM-iDataPlex servers interconnected with Mellanox InfiniBand fabric. Also, ALTAMIRA has a small GPU based cluster, with 5 IBM servers, each one with 2 GPU cards, and a cluster with IBM POWER7 blades, with capacity for up to 700 processes to execute intensive CPU applications.

Organisational Structure

Miguel Angel Nuñez and Luis Cabellos

The Altamira node has dedicated technical support, with oversight by the scientific computing divisions of both IFCA and ATC. The managers of the computing research lines of IFCA and ATC are also involved in the system administration and user support.

Technical and Scientific Highlights 2014

In 2014 the Altamira node executed applications corresponding to local users at the University of Cantabria with about five million hours of CPU.

Key Projects 2014

Computation from the Instituto de Biomedicina y Biotecnología de Cantabria

Ignacio Varela leads the computing work in Instituto de Biomedicina y Biotecnología de Cantabria. The IBBTEC is a strategic centre for the development of biomedical science in Cantabria. It was created in April 2007 as a joint Centre between CSIC (Spanish National Research Council), University of Cantabria and Government of Cantabria. The main mission of this Institute is to carry out a high level research as well as the transfer of technology in order to stimulate the productive sectors related to health and biotechnology. With the help of Altamira supercomputer IBBTEC has been conducting studies on lung cancer, Parkinson's disease, and others.

Constraints on inflationary models of the universe based on CMB

Enrique Martinez leads the Cosmic Microwave Background Radiation (CMB) research group at IFCA. CMB represents an essential tool for the research in Modern Cosmology. There are a large number of ground-based, balloon-borne and satellite experiments both current and planned. The existence of the CMB is a proof of the primordial explosion widely-known as Big-Bang. The anisotropies of the black body radiation temperature measured in different directions of the sky provide valuable information about the primordial epochs of the universe and its evolution. The standard inflation theory, developed in the 1980's and nowadays widely accepted, predicts that these anisotropies follow very closely a Gaussian distribution. The detection of non-Gaussian deviations in the CMB would have far-reaching consequences for our understanding of the universe.

RNA-seq analysis service

Rafael Zardoya and Etienne Kornobis lead the development of a Genomic service that uses Altamira. High throughput sequencing (HTS) methods are drastically changing the face of modern Biology studies. RNA-seq refers to the use of such methods to characterise the RNA content of a biological sample. Currently, the analysis of the data produced by these new methods require both high computing resources and Bioinformatic know-how. Consequently, they are developing TRUFA, a free webserver designed for fast and user-friendly RNA-seq analysis by using the Altamira cluster and reducing the amount of Bioinformatic knowledge necessary.
