Redis is an open-source in-memory data structure store, used as a database, cache, and message broker. This test profile is for testing any system-installed Redis copy. The redis-server and redis-benchmark software must be present in PATH. To use a static / locally built version of Redis, run the pts/redis test profile instead. Learn more via the OpenBenchmarking.org test page.
ONNX Runtime is developed by Microsoft and partners as a open-source, cross-platform, high performance machine learning inferencing and training accelerator. This test profile runs the ONNX Runtime with various models available from the ONNX Zoo. Learn more via the OpenBenchmarking.org test page.
