System Latency OS 5.2.1 rt1
Latency tests use rt-tests' cyclictest to deploy as many threads as there are cores. Stress tests (heavy load) use stress-ng. Test script is in bin directory:
runtestrt XXXX Y
# XXXX: test index. Output fies will containt this index
# Y stress mode. 0: no stress. 1: stress
Note that this is an extreme test case where all cores are occupied and there is no "idle" compute resource where pthreads can go. Typical performance for a cacao setup should be significanty better.
