SPEC CPU 2026 Build & Run Tool

Prerequisites: obtain your own copy of SPEC CPU 2026, then copy the benchspec/ folder into this directory.

Usage

./spec2026.py build intrate       # build integer rate benchmarks
./spec2026.py build fprate        # build floating-point rate benchmarks
./spec2026.py build intspeed      # build integer speed benchmarks
./spec2026.py build fpspeed       # build floating-point speed benchmarks

./spec2026.py run intrate         # run integer rate benchmarks
./spec2026.py run fprate          # run floating-point rate benchmarks
./spec2026.py run intspeed        # run integer speed benchmarks
./spec2026.py run fpspeed         # run floating-point speed benchmarks

./spec2026.py clean               # clean all build artifacts
./spec2026.py list                # list all available benchmarks
./spec2026.py list-sets           # list benchmark sets
./spec2026.py list-configs        # list build configs
