Clusters computacionales para la investigación: personalizables, eficientes, amigables y a costo cero.

This paper presents UnaGrid/UnaCloud: an opportunistic computing infrastructure solution, which provides fundamental computing resources (processing, storage and networking) on demand and at lower cost, to support academic and e-Science projects. The proposed computing infrastructure is provided through the opportunistic use of idle computing resources available in a university campus. This paper describes the architectures defined, implementations deployed and test cases. The results obtained evidence high efficiency in result generation, improving limitations of projects depending on the agile provision of large computational capabilities, including scientific and academic initiatives.
