In the last few years Computing has been caracterized by the advent of "multicore cpus". Effective exploitation of this new kind of computing architecture requires the adaptation of legacy software and enventually a shift of the programming paradigms to massive parallel. In this talk we will introduce the reasons that brough to the introduction of "multicore" hardware and the consequencies on...

Increasing the dimension of data samples for data analyses and using advanced algorithms for background suppression (such as unbinned maximum likelihood fits) require high CPU performance. Recently, vendors like Intel and AMD have not incremented the performance of single CPU unit as in the past, but they are working on multi-core CPU. Currently we have up to 8 cores implemented on one single...
