A Scalable FPGA-Based Network Processor for Scientific Computing

Several problems in scientific computing require surprisingly large computing power which current HPC commercial systems cannot deliver. The development of application-driven machines has to be taken into account since it can be the only viable and rewarding approach. The properties of the network are relevant for the overall performances, since latencies and low-transfer data rate may negatively affect the execution time. In this book will be presented a high-bandwidth and low-latency Network Processor specifically designed for high-performance computing, undertaking a process of analysis and development, starting from the definition of the hardware level, up to the higher software layers, through the interface with the modern CPUs, operating system management/interaction, the definition of the various user libraries and examples of applications that fully exploit the potential of the system. This Network Processor has been deployed in several massively parallel machines, allowing the maximum effectiveness in the simulation campaigns undertaken.
