Standard Performance Evaluation Corporation
The increasing demand for energy-efficient IT equipment has resulted in the need for power and performance benchmarks. In response, SPEC formed the SPECpower Committee, whose role is to augment existing and create new industry-standard benchmarks and tools with a power/energy measurement.
The SPEC Power benchmark is the first industry-standard benchmark that evaluates the power and performance characteristics of single server and multi-node servers. It is used to compare power and performance among different servers and serves as a toolset for use in improving server efficiency. The benchmark is targeted for use by hardware vendors, IT industry, computer manufacturers, and governments.
The first SPEC Power® benchmark suite was created to measure the power and performance characteristics of server-class computer equipment. The first release is known as the SPECpower_ssj® 2008 benchmark suite. It is available for purchase via the SPEC Power purchase button below.
The drive to create the power and performance benchmark came from the recognition that the IT industry, computer manufacturers, and governments are increasingly concerned with the energy use of servers. This benchmark provides a means to measure power (at the AC input) in conjunction with a performance metric. This helps IT managers to consider power characteristics along with other selection criteria to increase the efficiency of data centers.
The workload exercises the CPUs, caches, memory hierarchy and the scalability of shared memory processors (SMPs) as well as the implementations of the JVM (Java Virtual Machine), JIT (Just-In-Time) compiler, garbage collection, threads and some aspects of the operating system. The benchmark runs on a wide variety of operating systems and hardware architectures and should not require extensive client or storage infrastructure.
Since this is the first industry power-performance benchmark, a general methodology (http://www.www.sqzhongjian.com/power/docs/SPEC-Power_and_Performance_Methodology.pdf) for power measurement has been documented to assist other benchmark developers interested in measuring power.
