Computer systems traditionally take a long time to build because the major stages --- architecture, implementation/verification, and software --- tend to be serialized. Architecture is often almost complete before implementation/verification really starts. Likewise, hardware is often available before software development really starts. A possible reason for this serialization is the lack of a single environment in which all such development can proceed simultaneously.

In this talk, I will describe a simulation strategy that can provide that single environment. The strategy enables aggressively parallelized simulators capable of simulating the behavior of complex computers (multicore, x86, speculative out-of-order, aggressive memory models, reliability events, power estimation, etc.) that run fast enough (10MIPS-100MIPS per host core) for software development and tuning, while simultaneously being accurate enough (up to RTL-level) for architectural evaluation. In addition, the simulator description can potentially be synthesized to an implementation, making the simulator development effort directly useable by the implementation, and thus dramatically reducing the implementation effort and time.

Derek Chiou is an assistant professor at the University of Texas at Austin. His research areas are high performance computer simulation, computer architecture, parallel computing, Internet router architecture, and network processors. For five years before going to UT, Dr. Chiou was a system architect at Avici Systems, a manufacturer of terabit core routers. Dr. Chiou received his Ph.D., S.M. and S.B. degrees in Electrical Engineering and Computer Science from MIT. His research is supported by a DOE Career award, an NSF CAREER award, NSF and SRC awards as well as donations and grants from Intel, IBM, Xilinx, Freescale, Altera, and VMWare.
