Significant advances have been made in compilation technology for capitalizing on instruction-level parallelism (ILP). In addition, we extend these micro-benchmarks through MPAC library to measure the scaling characteristics of our target multi-core processors based platforms. We also develop a CPU micro-benchmark using our own specifications. We use these benchmarks to validate MPAC based performance measurements for single thread on Intel, AMD, and Cavium multi-core processors based platforms. We describe the software architecture of MPAC and demonstrate its efficacy by implementing the specifications of well-known Stream and Netperf micro-benchmarks. In this paper, we introduce multi-core processor architecture and communication (MPAC) benchmarking library, which provides a common infrastructure for developing specification-driven micro-benchmarks, application benchmarks, and network traffic load generators. Developing benchmarks for multi-core systems is a cumbersome task due to underlying parallel architecture and complexity of parallel programming paradigms. With wide adoption of multi-core processor based systems, there is a need for benchmarking such systems at both application and operating system levels. But when the threads are few, the performance of Core 2 Duo is better when compared to Corei3 processor. Obviously the multi core processors will give better results than the single core atom or Pentium IV processors. The results show that performance of multi core processors is better in multithreaded situation. Here four different processors are considered namely Corei3, Core 2 Duo, Pentium IV and Asus atom processor, the runtime under multithreaded benchmark suite is obtained. To avoid this, the standard benchmark named wPrime is considered for performance measurement for multithreaded environment. As though we can make use of any kind of simulation tools with a sample application, the behavior of measuring the entire performance is not possible because the processor may make use of its resource for any other I/O operations also. How can we measure the performance of different processors for multithreaded environment is challenging problem. There are various standard benchmarks available. Benchmarking plays an important role in performance measure.
