[RFC] rt-app: add script to generate small task workloads

by pi-cheng.chen

Some examples to use the script to generate small tasks workloads: 1. to generate a workload with 4 threads, 10% load and 30ms period $ ./small_task_gen -t 4 -l 10 -p 3 2. to generate a workload with 3 threads, 15% load and random tick-aligned period $ ./small_task_gen -t 3 -l 15 -r --aligned 3. to generate a workload with 5 threads, 20% load and random non-tick-aligned period $ ./small_task_gen -t 5 -l 20 -r --unaligned --- doc/examples/small_task_gen | 117 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 117 insertions(+) create mode 100755 doc/examples/small_task_gen diff --git a/doc/examples/small_task_gen b/doc/examples/small_task_gen new file mode 100755 index 0000000..ba74753 --- /dev/null +++ b/doc/examples/small_task_gen @@ -0,0 +1,117 @@ +#!/usr/bin/env python + +import sys +import getopt +import random + +outfile = "small_tasks.json" +tasks = None +loading = None +period = None +randomized = None +aligned = None + + +def usage(): + print "Usage:" + print sys.argv[0] + " -t <number of tasks>" + print "\t\t -l <percentage of task loading> (1 - 100)" + print "\t\t -p <fixed period in ms>" + print "\t\t -r [--aligned | --unaligned] (randomize periods of tasks)" + print "\t\t -o <output JSON file name> (default: small_tasks.json)" + return + + +def parse_options(): + global outfile + global tasks + global loading + global period + global randomized + global aligned + + try: + opts, args = getopt.getopt(sys.argv[1:], "t:l:o:p:rh", + ["aligned", "unaligned"]) + except getopt.GetoptError: + usage() + sys.exit(2) + + for o, a in opts: + if o == "-t": + tasks = int(a) + print "number of tasks: %d" % tasks + if o == "-l": + loading = int(a) + print "task loading: %d" % loading + if o == "-o": + outfile = a; + print "output workload JSON file: " + outfile + if o == "-p": + period = int(a) + print "period of tasks: %d" % period + if o == "-r": + randomized = True + print "randomized: %r" % randomized + if o == "--aligned": + if aligned == False: + usage() + sys.exit(2) + aligned = True + print "aligned: %r" % aligned + if o in "--unaligned": + if aligned == True: + usage() + sys.exit(2) + aligned = False + print "aligned: %r" % aligned + if o == "-h": + usage() + sys.exit(2) + + if not period is None and not randomized is None: + usage() + sys.exit(2) + + if tasks is None or (period is None and randomized is None): + usage() + sys.exit(2) + + return + + +def generate_workload(): + try: + f = open(outfile, "w") + except IOError: + print "WARN: Unable to open " + infile + sys.exit(2) + + f.write("{\n") + f.write("\t\"tasks\" : {\n") + + for i in range(0, tasks): + + if randomized is None: + period_ns = period * 1000 + else: + period_ns = random.randrange(1, 6) * 10000 # random tick-aligned period from 10ms~50ms + if aligned == False: # add a period offset randomly from 1 of [300, 500, 700] + period_ns += (3000, 5000, 7000)[random.randrange(0, 3)] + + run_ns = period_ns * loading / 100 + + f.write("\t\t\"thread%d\" : {\n" % i) + f.write("\t\t\t\"loop\" : -1,\n") + f.write("\t\t\t\"run\" : %d,\n" % run_ns) + f.write("\t\t\t\"timer\" : { \"ref\" : \"tick\", \"period\" : %d },\n" % period_ns) + f.write("\t\t},\n") + + f.write("\t},\n") + f.write("}\n") + return + + +if __name__ == '__main__': + parse_options() + generate_workload() -- 1.9.1

[rt-app 0/3] Dependencies and example files fixes

by Ivan T. Ivanov

Hi, Here small set of patches which fix: - Build time dependencies. Application actually depend on json-c - Add __aarch64__ sched_setget|set_attr syscall numbers. - Fixed "suspend" event definition in example files. JSON expect object of type string after event definition. Hopefully I get it right. If you have any questions or/and comments, please let me know. Regards, Ivan Ivan T. Ivanov (3): fixup json-c dependencies add get/setattr for __aarch64__ fix suspend event definitions configure.ac | 12 ++++++------ doc/examples/browser.json | 8 ++++---- doc/examples/example4.json | 4 ++-- doc/examples/mp3.json | 8 ++++---- doc/examples/test.json | 4 ++-- libdl/dl_syscalls.h | 5 +++++ src/rt-app_parse_config.h | 2 +- 7 files changed, 24 insertions(+), 19 deletions(-) -- 1.9.1
