PhD Thesis

I read the PhD thesis in 1998. It's title was "Recursos anchos: una técnica de bajo coste para explotar paralelismo agresivo en códigos numéricos". It was written in spanish and the translation of the title is (more or less) "Wide Resources: a Low-cost Technique to Exploit Aggressive Parallelism in Numerical Code". My advisors were Mateo Valero and Josep Llosa. I haven't translate it, but you can read the main ideas at the Transactions on Computers 2001 article (see below).
