SPECpower_ssj® 2008

The SPEC Power® benchmark suite measures the power and performance characteristics of server-class computer equipment. It is used to compare power and performance among different servers and serves as a toolset for use in improving server efficiency. This benchmark is targeted for use by hardware vendors, IT industry, computer manufacturers, and governments.

SPECpower_ssj® 2008 is the first industry-standard benchmark that evaluates the power and performance characteristics of single server and multi-node servers.

The SPECpower_ssj® 2008 benchmark is available for purchase via the SPEC® order form.

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.spec.org/power/docs/SPEC-Power_and_Performance_Methodology.pdf) for power measurement has been documented to assist other benchmark developers interested in measuring power. For information about the SPEC Power committee, see here.

The PTDaemon tool updates: A new version, v1.7.1, was released March 10th, 2015.

The minimum PTDaemon tool version for SPECpower_ssj® 2008 submissions is v1.7.0 as of Feb 3rd, 2015

All SPECpower_ssj® 2008 submissions after September 15th, 2015 must be made with v1.7.1 of the PTDaemon tool or newer.

Support

Technical support requiring involvement of benchmark specialists is done by volunteers from our member institutions (see member list). Please do not send us any proprietary information in your queries. If you feel you cannot clearly ask your question without reference to proprietary information please clearly mark such communications and we will not involve our benchmark specialists, but rather will answer your query only if SPEC's own staff benchmark generalists are able to do so.
