Example log:

Detecting CPU topology and computing scheduling classes:
  Linux, using /sys/devices/system/cpu
  2 packages, 1 core per package, 1 thread per core

  CPU lists:
    Package #0, Core #0, Threads: 0
    Package #1, Core #1, Threads: 1, 2, 3, 4, 5, 6, 7

  Scheduling classes for matching tests:
    2 actors:
      (PG 0, CG 0), (PG 1, CG 1)

  Hardware CPUs in use: 8, using plain hard busywait.
  Test preset mode: "default"
  Writing the test results to "jcstress-results-2021-06-19-00-31-24.bin.gz"
  Parsing results to "results/"
  Running each test matching ".*" for 1 forks, 5 iterations, 1000 ms each
  Solo stride size will be autobalanced within [10, 10000] elements, but taking no more than 128 Mb.

  Attached the non-interactive output stream.
  Printing the progress line at most every 15000 milliseconds.
