The command line is
stress-ng --class cpu --sequential $(nproc) --timeout 1 --times --verify --metrics-brief
The test box is
model: Broadwell-EP
nr_cpu: 88
memory: 128G
It shows up 4 times in 6 test runs:
/result/stress-ng/60s-cpu-performance/lkp-bdw-ep6/debian-x86_64-2016-08-31.cgz/x86_64-rhel-7.2/gcc-6/bb176f67090ca54869fc1262c913aa69d2ede070/matrix.json
