Compare your results . We also model the L1, L2 and L3 caches. In this paper, we advocate that in many interesting cases, a careful static analysis of assembly code can achieve similar results at a much lower cost and with a better accuracy. Then ASTEX construct a thread speculative model for each hot-path. An inappropriate algorithm can increase computation time and cost. We are trying to help a computer designer build a computer, B, which will run this program in 6 seconds. The cloud model allows the access to a vast amount of computational resources, alleviating the need for acquisition and maintenance costs on a pay-per-use basis. Also, the changes in IPC due to design changes are found to be proportional to the changes in IPC in the original applications. We introduce a new technique, decremental analysis (DECAN), to iteratively identify the individual instructions responsible for performance bottlenecks. By using a set of SPEC CPU 2000 benchmarks we demonstrate that these models improve representativeness of synthetic workloads by providing better correlation with the original code across a wide range of cache configurations and branch predictors. Future Simsys plans include model enhancement with more HW details and much more extensive experimentation. The main contribution of this methodology is a semi-automatic prediction of the performance for sequential applications on a set of parallel architectures. Computer Performance Engineering 11th European Workshop, EPEW 2014, Florence, Italy, September 11-12, 2014. Therefore, a parameter that has a large effect on the execution time accounts for a significant amount of variability in the execution time, which makes it a significant performance bottleneck (since changing the parameter's value results in large changes in the execution time). Haverkort, Performance of computer Communication Systems, John Wiley & Sons Ltd., 1998 . Recent research [2] [14] has demonstrated that it is possible to automatically construct such synthetic workloads by measuring performance statistics that uniquely characterize an application and modeling them into synthetic workloads. Computer performance improvement embraces many issues, but is severely hampered by existing approaches that examine one or Speed up your computer. We are trying to help a computer designer build a computer, B, which will run this program in 6 seconds. Find more ways to speed up your computer. We do this by giving some design examples which utilize the GB very efficiently. All rights reserved. Inversely to traditional measurement methods and modeling, the proposed tool considers static metrics to analyze and tune application performance. Thus, an objective comparison has become a harder task. Given any application, we are able to characterize it and generate a synthetic version of the application with approximately the same instruction stream characteristics.
