NAME

       signaltest - signal roundtrip test software

SYNOPSIS

       signaltest  [  -a|--affinity NUM] [ -b|--backtrace USEC ] [-D|--duration TIME] [-h|--help]
       [--json  FILENAME]  [-l|--loops  LOOPS  ]   [-p|--prio   PRIO]   [-q|--quiet]   [-S|--smp]
       [-t|--threads NUM] [-m|--mlockall ] [-v|--verbose ]

OPTIONS

       These  programs  follow the usual GNU command line syntax, with long options starting with
       two dashes ('--').

       -a, --affinity[=PROC-SET]
              Run threads on the set of  processors  given  by  PROC-SET.   If  PROC-SET  is  not
              specified,  all processors will be used.  Threads will be assigned to processors in
              the set in numeric order, in a round-robin fashion.
              The set of processors can be specified as A,B,C, or A-C, or A-B,D-F,  and  so  on*.
              The  !  character  can be used to negate a set.  For example, !B-D means to use all
              available CPUs except B through D.  The cpu numbers are the same as  shown  in  the
              processor  field  in /proc/cpuinfo.  See numa(3) for more information on specifying
              CPU sets.  * Support for CPU sets requires libnuma version >= 2.  For  libnuma  v1,
              PROC-SET, if specified, must be a single CPU number.

       -b, --breaktrace=USEC
              Send break trace command when latency > USEC

       -D, --duration=TIME
              Specify a length for the test run.
              Append 'm', 'h', or 'd' to specify minutes, hours or days.

       --help
              display usage information

       --json=FILENAME
              Write final results into FILENAME, JSON formatted.

       -l, --loops=LOOPS
              Number of loops: default=0 (endless)

       -p, --priority=PRIO
              Priority of highest priority thread

       -q, --quiet
              print a summary only on exit

       -S, --smp
              Set  options  for standard testing on SMP systems. Equivalent to using the options:
              "-t -a" as well keeping any specified priority equal across all threads

       -t, --threads=NUM
              number of threads: default=2

       -m, --mlockall
              lock current and future memory allocations

       -v, --verbose
              output values on stdout for statistics
              format: n:c:v n=tasknum c=count v=value in us
