We present the results from a two-day study in which we discussed various\nimplementations of Smooth Particle Hydrodynamics (SPH), one of the leading\nmethods used across a variety of areas of large-scale astrophysical\nsimulations. In particular, we evaluated the suitability of designing special\nhardware extensions, to further boost the performance of the high-end general\npurpose computers currently used for those simulations. We considered a range\nof hybrid architectures, consisting of a mix of custom LSI and reconfigurable\nlogic, combining the extremely high throughput of Special-Purpose Devices\n(SPDs) with the flexibility of reconfigurable structures, based on Field\nProgrammable Gate Arrays (FPGAs). The main findings of our workshop consist of\na clarification of the decomposition of the computational requirements,\ntogether with specific estimates for cost/performance improvements that can be\nobtained at each stage in this decomposition, by using enabling hardware\ntechnology to accelerate the performance of general purpose computers.\n
