SPEC Open System Group

Open Systems Group

The Open Systems Group is the oldest group within SPEC. The OSG is the current embodiment of the original founders of SPEC. The OSG is governed by the policies and principles described in the SPEC Open Systems Group Policies and Procedures Document. The Open Systems Steering Committee (OSSC) provides oversight and management for a number of technical committees that investigate and develop the benchmarks, metrics, run and reporting rules, and so on.

OSG focus is on component- and systems-level benchmarks for desktop systems, workstations and servers running open operating system environments. This is the group responsible for the processor metrics SPECint®2017 and SPECfp®2017 (and their predecessors in 2006, 2000, 1995, 1992 and the original SPECmarks from 1989).

In addition to the SPEC CPU® 2017 benchmark suite, the group has also developed Java benchmarks, a SIP benchmark, web server benchmarks, mail server benchmark, file server benchmarks, a power and performance benchmark, and the virtualization benchmarks. More in-depth information may be found in the benchmark specific links below.

This major release 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.

Version 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.
SPEC PTDaemon® tool: The SPEC PTDaemon tool is used to control power analyzers in benchmarks which contain a power measurement component.

Future Benchmarks

These are the projects that SPEC has currently under active development for future release.

SPEC ML: The OSG ML Committee was formed in 2021 to develop practical methodologies to benchmark machine learning (ML) performance in the context of real-world platforms and environments. The Committee also works with other SPEC committees to update their benchmarks for ML environments. The OSG ML Committee's first benchmark, SPEC ML, will measure end-to-end performance of a system under test (SUT) handling ML training and inference tasks.
