This paper presents a method to derive efficient algorithms for hypercubes. The method exploits two features of the underlying hardware: a) the parallelism provided by the multiple communication links of each node and b) the possibility of overlapping computations and communications which is a feature of machines supporting an asynchronous communication protocol. The method can be applied to a generic...
In this paper, we present an efficient parallel system with an interconnection network customized for Positron Emission Tomography (PET) image reconstruction. The proposed parallel reconstruction system has two distinguished features. On feature is that the interconnection network is optimal for both filtered backprojection and EM algorithms, rather than only for one of them. The other feature is...
