Abstract:

The main goal was to learn through simulation about the functionality and performance on realistic applications of an RRM system consisting of a collection of RRM ensemble chips each such chip being a SIMD processor connected on a network, and to design mechanisms to support the simultaneous parallel computation of applications across many such ensemble chips. To achieve these goals we first built a high-level interensemble simulator and ran a collection of benchmarks on it under varying assumptions about several architectural parameters to obtain a first estimate of the communication requirements for the RRM and to determine the feasibility of those requirements in view of existing network technology. Using a second, very detailed register- transfer level simulator of a single ensemble and the performance results of a collection of applications run on it, together with modeling above the ensemble level, we also estimated interensemble performance in this way we were able to obtain more detailed and accurate interensemble performance estimates. Mechanisms supporting parallel computations across many ensembles were also studied and designed
