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
