This user's guide for the Altamira supercomputer is intended to provide the minimum amount of information needed by a new user of this system. As such, it assumes that the user is familiar with many of the standard aspects of supercomputing as the Unix operating system. We hope you can find most of the information you need to use our computing resources: from applications and libraries to technical documentation about Altamira. Please read carefully this document and if any doubt arises don't hesitate to contact our support group at <res_support@ifca.unican.es>. == System Overview == |

Introduction
This user's guide for the Altamira supercomputer is intended to provide the minimum amount of information needed by a new user of this system. As such, it assumes that the user is familiar with many of the standard aspects of supercomputing as the Unix operating system.
We hope you can find most of the information you need to use our computing resources: from applications and libraries to technical documentation about Altamira. Please read carefully this document and if any doubt arises don't hesitate to contact our support group at <res_support@ifca.unican.es>.
System Overview
Altamira comprises 156 compute nodes, 5 GPU compute nodes, a login server and several service servers. Every compute node has two processors at 2.6 GHz running Scientific Linux 6.2 system with 64 GB of memory RAM and 400 GB local disk storage. All the servers provide a total of 132 TB of disk storage accessible from every compute node through GPFS (Global Parallel File System).
The networks that interconnect the Altamira are:
- Infiniband Network: High bandwidth network used by parallel applications communications.
- Gigabit Network: Ethernet network used by the management server.
