Introduction to the SPEC CPU 2026 Benchmark Suite License Agreement
Freely-redistributable sources
Note 1: Licenses and bug reporting
Note 2: about "BSD" licenses
The SPEC CPU®2026 Benchmark Suite is a product of the SPEC® non-profit corporation (about SPEC). The SPEC CPU 2026 source code and tools are provided under a SPEC License Agreement(pdf format). The license contains the terms and conditions of your agreement with SPEC. Read it carefully before using the product. A copy is also on your distribution media, in the Docs/licenses/ directory.
The following points are not a substitute for that License Agreement, but may be helpful as an introduction:
Public use is governed by:
SPEC gratefully acknowledges the many free and open source software contributions that are used in SPEC CPU 2026 benchmark suites.
In the table below, several benchmarks are marked as using the GNU GPL. For each, SPEC's updated sources are available in the ISO image for your copy of the SPEC CPU 2026 benchmark suite, in a compressed tar file underneath redistributable_sources/modified.
One possible use for modified sources is for bug reporting. If you wish to provide an entire benchmark to a compiler developer, generally you are not allowed to do so, unless the developer also has a license for the SPEC CPU 2026 benchmark suite. The exception is for the GPL benchmarks: for those, you may, if you wish to do so, pass along the tarball from redistributable_sources/modified. In that situation, please note that:
SPEC tried to track down all software license references within all files in the SPEC CPU 2026 benchmark suites. Many modules were found with BSD (or similar) licenses. Copyrights for such modules must be acknowledged in the documentation if they are shipped in binary form. Separate acknowledgment is not required if they ship as source code (which is how SPEC CPU 2026 ships).
Nevertheless, having identified these modules, it seems only courteous to acknowledge them -- even if not legally required. The document you are reading now directly acknowledges many of them; in some cases, this document links to separate documents that include the acknowledgment.
When considering BSD licenses, one should be careful not to confuse "acknowledgment" with "advertising". To the best of SPEC's knowledge, no BSD-licensed materials in the SPEC CPU 2026 product require advertisement. (There are a few source files that mention such a clause, but the requirement has been explicitly disclaimed; see for example the BSD statement and the license notes for 735.gem5_r, below).
This section lists the licenses that apply to the benchmarks in CPU 2026.

The SPEC benchmark was branched from the Stockfish 15 release. Support for endgame databases, embedding the neural network, and tuning the evaluation was removed, all output that is time-dependent was removed, and platform, compiler, or architecture specific micro-optimizations were disabled, removed, or replaced by portable C++ code. Stockfish is licensed under the GNU GPL version 3. The neural network file was taken from the Stockfish Neural Network Repository at tests.stockfishchess.org/nns, which distributes and shares the files through a CC0 public domain dedication (local copy). | |||||||||||||||||||||||||||

All the NTest code is distributed under the GNU General Public License Version 3 GPLv3.txt. SPEC added a version of the Mersenne-Twister PRNG that is licensed by its authors (Makoto Matsumoto, Takuji Nishimura, and Mutsuo Saito) under a BSD license. The original NTest is available at github: github.com/vladpetric/ntest. The SPEC CPU version is based on commit hash fc7d6b26. | |||||||||||||||||||||||||||

CACTUS originated from ET_2020_11 and can be downloaded by following the instructions at http://einsteintoolkit.org/download.html. The submitters contributed a trimmed version to SPEC and further modifications were made by SPEC to improve portability and eliminate unused code. CACTUS is distributed under the GNU General Public License v2. The submitters gave SPEC permission to use the code under GPLv2. CACTUS has several components referred to as flesh and thorns. Some components are licensed under LGPLv2 and others under GPLv2.

OMNET++ is licensed directly to SPEC by OpenSim Ltd. authors Marcel Marek and András Varga. Releases are available from omnetpp.org and OMNET++ sources are at GitHub. The 710.omnetpp_r benchmark is based on an April 2023 snapshot. The files simulator/common/yxml.c and yxml.h (available at https://code.blicky.net/yorhel/yxml) use the MIT License, copyrighted Yoran Heling. The benchmark includes a version of Mersenne Twister (available at https://doc.omnetpp.org/omnetpp/api/mersennetwister_8h_source.html) under the BSD license, copyrighted Makoto Matsumoto and Takuji Nishimura; Richard J. Wagner These files are generated by the Bison parser (GNU GPL) generator
The above are licensed under the same terms as the rest of the benchmark, not GPL, in accordance with the Bison special exception:
/* As a special exception, you may create a larger work that contains
part or all of the Bison parser skeleton and distribute that work
under terms of your choice, so long as that work isn't itself a
parser generator using the skeleton or a modified version thereof
as a parser skeleton. Alternatively, if you modify or redistribute
the parser skeleton itself, you may (at your option) remove this
special exception, which will cause the skeleton and the resulting
Bison output files to be licensed under the GNU General Public
License without this special exception.
This special exception was added by the Free Software Foundation in
version 2.2 of Bison. */

The text version of the Adobe Font Metrics license has been modified to include only the visible content from the original

The modifications, although invisible, are nevertheless prominently
noted, as is required.
A pointer is also included to the unmodified original.
(One cannot help but wonder if the inclusion of invisible ink was a little test?)
