We characterize the workload placed on both Pentium and Pentium Pro PCs running Windows NT Workstations 4.0 by three simple Web serving scenarios using the processor timestamp and performance counters. We used both the Pentium and the Pentium Pro to investigate the effect on the workloads of two processors that have the same instruction set architecture, but which have rather different microarchitectures. The workload shows a high percentage of branch instructions with only fair branch prediction for both processors. The numbers from the Pentium suggest a very low level of available instruction set parallelism at the instruction set architecture level while the improvement in the cycles per instruction (CPI) on the Pentium Pro indicates that there is more parallelism at the micro-operation level, even though the code makes somewhat inefficient use of the available resources.","PeriodicalId":190931,"journal":{"name":"Workload Characterization: Methodology and Case Studies.

The behavior of multiprocessor systems that use such processors is not well understood and very difficult to predict. We tackle this problem using a powerful simulator, Armadillo, and a novel characterization framework that breaks the instruction pipeline into five meta-stages. The Armadillo simulator models symmetric multiprocessors (SMPs) constructed from highly aggressive superscalar processors on a shared bus, and is able to provide accurate, detailed statistics on numerous aspects of the simulated system, including the amount of time each instruction spends in each of these five meta-stages. We also analyze the fraction of each instruction's lifetime, during which it remains speculative and the amount of time that an instruction spends on the critical path. To demonstrate the effectiveness of this approach, we apply the characterization to applications from the SPLASH-2 benchmark suite. We evaluated the applications' sensitivity to key memory system parameters: bus frequency, bus width, memory latency, and cache latency.","PeriodicalId":190931,"journal":{"name":"Workload Characterization: Methodology and Case Studies.

The application, extracted from the IBM Intelligent Miner, identifies groups of records that are mathematically similar, based on a neural network model called a self-organizing map. We examine and compare, in detail, two implementations of the application: (1) temporal locality or working set size; (2) spatial locality and memory block utilization; (3) communication characteristics and scalability; and (4) translation lookaside buffer (TLB) performance. First, we find that the working set hierarchy of the application is governed by two parameters, namely the size of an input record and the size of prototype array; it is independent of the number of input records. Second, the application shows good spatial locality, with the implementation optimized for sparse data sets having slightly worse spatial locality. Third, due to the batch update scheme, the application bears very low communication. Finally, a two-way set-associative TLB may result in severely skewed TLB performance in a multiprocessor environment, caused by the large discrepancy in the number of conflict misses. Increasing the set associativity is more effective in mitigating the problem than increasing the TLB size.","PeriodicalId":190931,"journal":{"name":"Workload Characterization: Methodology and Case Studies.
