SPECpower_ssj2008 is the first industry-standard SPEC benchmark that
evaluates the power and performance characteristics of volume server
class and multi-node class computers. With
SPECpower_ssj2008, SPEC is defining server
power measurement standards in the same way we have done for
The drive to create the power and performance benchmark comes from
the recognition that the IT industry, computer manufacturers, and
governments are increasingly concerned with the energy use of
servers. Currently, many vendors report some energy efficiency
figures, but these are often not directly comparable due to differences
in workload, configuration, test environment, etc. Development of
this benchmark provides a means to measure power (at the AC input) in
conjunction with a performance metric. This should help IT
managers to consider power characteristics along with other selection
criteria to increase the efficiency of data centers.
The initial benchmark addresses only one subset of server workloads:
the performance of server side Java. It 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. Additional workloads are planned.
Since this is the first power-performance
benchmark, a general methodology
measurement has been documented to assist other benchmark developers
interested in measuring power and in the hopes of establishing a common
set of practices in this new area of benchmarking.
