Dusting my Ph.D. thesis off

After attending Albert Orriols’s Ph.D. thesis defense, I ended wondering how many of the question I posted in mine have not been solved. The answer, quite a bit. So, I just decided to dig it up, and put it up here. Yes, the thesis was not written in English (in those days my fellowship had some strings attached), but math formulation, graphs, and results are readable in any language ;) Also, GALE was written and documented in english, and is available here. ...

Join me congratulating Albert Orriols, Ph.D.

Albert Orriols (for those who do not know him, a brilliant learning classifier systems researcher) defended his thesis today. The outcome: Excellent Cum Laude. Albert Orriols Ph.D. defense started at 11am at Enginyeria i Arquitectura La Salle in Barcelona. The thesis panel was presided by Prof. David E. Goldberg, and formed by members Prof. Francisco Herrera, myself, Dr. Martin Butz, and secretary Prof. Xavier Vilasís). I must say that it has been a great pleasure to read his remarkable thesis and great contributions to the Learning Classifier System field. I hope he will make it available soon, and encourage you to take a look at it. ...

Meandre: Semantic-Driven Data-Intensive Flows in the Clouds

by Llorà, X., Ács, B., Auvil, L., Capitanu, B., Welge, M.E., Goldberg, D.E. (2008). This paper has been accepted at the 4th IEEE International Conference on e-Science. An early draft of the paper can be found as IlliGAL technical report 2008013. You can download the pdf here. More information is also available at the Meandre website as part of the SEASR project. Abstract: Data-intensive flow computing allows efficient processing of large volumes of data otherwise unapproachable. This paper introduces a new semantic-driven data-intensive flow infrastructure which: (1) provides a robust and transparent scalable solution from a laptop to large-scale clusters,(2) creates an unified solution for batch and interactive tasks in high-performance computing environments, and (3) encourages reusing and sharing components. Banking on virtualization and cloud computing techniques the Meandre infrastructure is able to create and dispose Meandre clusters on demand, being transparent to the final user. This paper also presents a prototype of such clustered infrastructure and some results obtained using it. ...

New Semester and IACAT

Every new semester has its quickoff overhead. Besides trying to get back on track after travelling, and having meeting after meeting, now I am sitting at the inagural act of the Institute for Advanced Computing Applications and Technologies at the University of Illinois at Urbana-Champaign. A list and description of the three kicking off projects of the center is also available. These three themes are: Next-Generation Acceleration Systems for Advanced Science and Engineering Applications Multiscale Simulation in Science and Engineering Synergistic Research on Parallel Programming for Petascale Applications Quite and interesting mix to follow. ...
