The programmability challenges to general-purpose parallel computing desperately need computer hardware and software researchers to work together on the solutions. However, the unacceptably slow speed of current full-system simulators limits the multiprocessor/multi-core research.The proposed ProtoFlex project develops an FPGA-accelerated simulation technology to deliver the necessary simulation performance to enable full-scale software research on top of simulated experimental architectures. ProtoFlex simulators are not FPGA prototypes. The ProtoFlex simulation architecture relies on hardware virtualization to achieve full-system fidelity and system scalability, while mitigating the complexities associated with conventional FPGA prototyping. This project will develop a hybrid simulation with transplanting and with interleaving of multiple processor contexts, with the goal to decouple the required complexity of the hardware construction from the complexity of a very large target multiprocessor system. This project will also investigate in-hardware techniques for real-time, deep instrumentation and analysis of simulation events.

通用并行计算的可编程性挑战迫切需要计算机硬件和软件研究人员共同努力解决。然而，目前的全系统仿真器的速度慢得令人无法接受的限制了多处理器/多核的研究，提出的ProtoFlex项目开发了一种FPGA加速的仿真技术，提供必要的仿真性能，使全面的软件研究的模拟实验架构。ProtoFlex模拟器不是FPGA原型。ProtoFlex仿真架构依赖于硬件虚拟化来实现全系统保真度和系统可扩展性，同时减轻与传统FPGA原型设计相关的复杂性。 该项目将开发一个混合仿真移植和多处理器上下文的交织，目标是解耦所需的硬件结构的复杂性从一个非常大的目标多处理器系统的复杂性。 本项目还将研究用于实时，深度仪器和模拟事件分析的硬件技术。
