Graphics and Workstation Performance


  • Handheld
    In 2013 SPEC formed a committee chartered for the development of, and support for, a compute intensive benchmark suite for handheld devices. In 2017, recognizing the reduced interest in this work, this committee was dissolved.

High Performance Computing, OpenMP, MPI, OpenACC, OpenCL

    [benchmark info] [published results] [support] [order benchmark]
    SPEC ACCEL tests performance with a suite of computationally intensive parallel applications running under the OpenCL and OpenACC APIs. The suite exercises the performance of the accelerator, host CPU, memory transfer between host and accelerator, support libraries and drivers, and compilers.

  • SPECjms2007
    [benchmark info] [published results] [support] [order benchmark]
    SPECjms2007 is the first industry-standard benchmark for evaluating the performance of enterprise message-oriented middleware servers based on JMS (Java Message Service). It provides a standard workload and performance metrics for competitive product comparisons, as well as a framework for indepth performance analysis of enterprise messaging platforms.

  • SPECjvm2008
    [benchmark info] [published results] [support] [download benchmark]
    SPECjvm2008 is a benchmark suite for measuring the performance of a Java Runtime Environment (JRE), containing several real life applications and benchmarks focusing on core java functionality. The SPECjvm2008 workload mimics a variety of common general purpose application computations.

  • SPECpower_ssj2008
    [benchmark info] [published results] [support] [order benchmark]
    SPECpower_ssj2008 is the first industry-standard SPEC benchmark that evaluates the power and performance characteristics of volume server class computers. The initial benchmark addresses the performance of server-side Java, and additional workloads are planned.


  • SPEC VIRT_SC 2013
    [benchmark info] [published results] [support] [order benchmark]
    SPEC's updated benchmark addressing performance evaluation of datacenter servers used in virtualized server consolidation. SPEC VIRT_SC 2013 measures the end-to-end performance of all system components including the hardware, virtualization platform, and the virtualized guest operating system and application software. The benchmark supports hardware virtualization, operating system virtualization, and hardware partitioning schemes.

  • Server Efficiency Rating Tool (SERT) 2.0
    [benchmark info] [support] [order benchmark]
    The Server Efficiency Rating Tool (SERT) was created by Standard Performance Evaluation Corporation (SPEC) at the request of the US Environmental Protection Agency. The SERT 2.0 adds a single-value metric, reduces runtime, improves automation and testing, and broadens device and platform support. Designed to be simple to configure and use via a comprehensive graphical user interface, the SERT suite uses a set of synthetic worklets to test discrete system components such as processors, memory and storage, providing detailed power consumption data at different load levels.

    The SERT metric, created with the support of the RG Power Working Group, rates the server efficiency of single- and multi-node servers across a broad span of configurations.

  • Chauffeur Worklet Development Kit (WDK)
    [kit info] [forum] [order software]
    Chauffeur was designed to simplify the development of workloads for measuring both performance and energy efficiency. Because Chauffeur contains functions that are common to most workloads, developers of new workloads can focus on the actual business logic of the application, and take advantage of Chauffeur's capabilities for configuration, run-time, data collection, validation, and reporting.

    Chauffeur was initially designed to meet the requirements of the SERT. However, SPEC recognized that the framework would also be useful for research and development purposes. The Chauffeur framework is now being made available as the Chauffeur Worklet Development Kit (WDK). This kit can be used to develop new workloads (or "worklets" in Chauffeur terminology). Researchers can also use the WDK to configure worklets to run in different ways, in order to mimic the behavior of different types of applications. These features can be used in the development and assessment of new technologies such as power management capabilities.

    Version 2.0 is based on the SERT 2.0 infrastructure and includes significant enhancements to the hardware detection, customization options of generating HTML reports, and developer documentation. It has now reduced memory requirements for the Director when signing results files and reduced the size of the result output for large systems or clusters.

    Chauffeur WDK 2.0 added worklet-specific normalization of results and an updated list of supported operating systems including Ubuntu (14.04 LTS and 16.04 LTS) as well as current versions of Windows Server, RHEL, SLES, AIX, and Solaris. The WDK also includes the latest PTDaemon integration for power analyzers and temperature sensors, along with data collection, validation and reporting.
  • PTDaemon
    The SPEC PTDaemon software is used to control power analyzers in benchmarks which contain a power measurement component.
