“…Efforts are also made to evaluate comparable architectures in Prior works. Peng et al [33] [34] analyze the memory hierarchy of early dual-core processors from Intel and AMD and demonstrate their respective characteristics. In [28], Hackenberg et al conduct a comprehensive investigation on the cache structures on advanced quad-core multiprocessors.…”

In recent years, modern graphics processing units have been widely adopted in high performance computing areas to solve large scale computation problems. The leading GPU manufacturers Nvidia and ATI have introduced series of products to the market. While sharing many similar design concepts, GPUs from these two manufacturers differ in several aspects on processor cores and the memory subsystem. In this paper, we choose two recently released products respectively from Nvidia and ATI and investigate the architectural differences between them. Our results indicate that these two products have diverse advantages that are reflected in their performance for different sets of applications. In addition, we also compare the energy efficiencies of these two platforms since power/energy consumption is a major concern in the high performance computing system.

“…This technique eventually led to complex and hard to manage processors, in addition these processors consume large amount of power emitted in the form of high temperature and the problem is become worse the greater the speed of the processor [11] . To resolve this problem, it was necessary to reduce the speed of processors and combine multiple cores on the same chip [12,13] .…”

Problem statement:In the midst of the huge development in processors industry as a response to the increasing demand for high-speed processors manufacturers were able to achieve the goal of producing the required processors, but this industry disappointed hopes, because it faced problems not amenable to solution, such as complexity, hard management and large consumption of energy. These problems forced the manufacturers to stop the focus on increasing the speed of processors and go toward parallel processing to increase performance. This eventually produced multicore processors with high-performance, if used properly. Unfortunately, until now, these processors did not use as it should be used; because of lack support of operating system and software applications. Approach: The approach based on the assumption that single-kernel operating system was not enough to manage multi-core processors to rethink the construction of multi-kernel operating system. One of these kernels serves as the master kernel and the others serve as slave kernels. Results: Theoretically, the proposed model showed that it can do much better than the existing models; because it supported single-threaded processing and multi-threaded processing at the same time, in addition, it can make better use of multi-core processors because it divided the load almost equally between the cores and the kernels which will lead to a significant improvement in the performance of the operating system. Conclusion: Software industry needed to get out of the classical framework to be able to keep pace with hardware development, this objective was achieved by re-thinking building operating systems and software in a new innovative methodologies and methods, where the current theories of operating systems were no longer capable of achieving the aspirations of future.

As chip multiprocessor (CMP) has become the mainstream in processor architectures, Intel and AMD have introduced their dual-core processors. In this paper, performance measurement on an Intel Core 2 Duo, an Intel Pentium D and an AMD Athlon 64 Â 2 processor are reported. According to the design specifications, key derivations exist in the critical memory hierarchy architecture among these dualcore processors. In addition to the overall execution time and throughput measurement using both multi-program-med and multithreaded workloads, this paper provides detailed analysis on the memory hierarchy performance and on the performance scalability between single and dual cores. Our results indicate that for better performance and scalability, it is important to have (1) fast cacheto-cache communication, (2) large L2 or shared capacity, (3) fast L2 to core latency, and (4) fair cache resource sharing. Three dual-core processors that we studied have shown benefits of some of these factors, but not all of them. Core 2 Duo has the best performance for most of the workloads because of its microarchitecture features such as the shared L2 cache. Pentium D shows the worst performance in many aspects due to its technology-remap of Pentium 4 without taking the advantage of on-chip communication.
