Complex models require high performance computing (HPC) which means Parallel Computing. That is a fact. The question we try to address in this paper is "which is the best suitable solution for HPC contexts such as rendering? Will it be possible to use it in General Purpose elaborations?" We start from these questions and analyze two different approaches, IBM CELL and the well known GPGPU, showing how changing our minds and breaking some assumptions can lead to unexpected results and open a whole set of new possibilities. We talk about rendering, but quickly move slightly towards general purpose computation, because many algorithms used in Visual Simulations are not only referred to rendering issues but to a wider range of problems.

Abstract
Complex models require high performance computing (HPC) which means Parallel Computing. That is a fact. The question we try to address in this paper is "which is the best suitable solution for HPC contexts such as rendering? Will it be possible to use it in General Purpose elaborations?" We start from these questions and analyze two different approaches, IBM CELL and the well known GPGPU, showing how changing our minds and breaking some assumptions can lead to unexpected results and open a whole set of new possibilities. We talk about rendering, but quickly move slightly towards general purpose computation, because many algorithms used in Visual Simulations are not only referred to rendering issues but to a wider range of problems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
