2019-05-10PLRsearch: Use stat trackers to shorten IntegratorVratko Polak1-3/+3
+ Extract several tracker classes and use them in Integrator. + Apply next_rate workarounds to focus more on critical region. + Rewrite stretch function, as the previous implementation was wrong. + Rework logging: ++ Use injected trace() function in Integrator. ++ Inject function that skips trace logging on default initialization. ++ Use the same multiprocessing-safe passing, but separate queue. + Set duration to 120m in Robot, but keep at 30m in Python. + Apply minor changes to make computations more reproducible: ++ Attempt to log everything needed by reproducibility in one line. ++ Log samples used, and make it settable as upper limit. ++ Use repr output in TRex scripts, to avoid rounding when copypasting. +- Numpy seems to be sharing PRNG between processes. +-- An edit to disable one thread is needed for full reproducibility. +-- Such an edit is prepared, but will not be merged anytime soon.

2019-02-26De-duplicate unidirection supportVratko Polak1-221/+46
- Latency is now reported in both directions. -- For unidirection that means additional -1/-1/-1. + Changed function argument wrapping to save vertical space. + Changed trex command synthesys to save vertical space. + Fixed handling of command line arguments to avoid superfluous spaces. + More care distinguishing (0, 1) from (port_0, port_1). - Not renaming the original port arguments.

2019-01-08[V4] Add sending unidirectional traffic support for TG in CSITYulong Pei1-5/+205
Extend TG in CSIT to support to send unidirectional traffic, and then it can be used by unidirectional test cases e.g. Load balancer. Change-Id: Ie25bcdf7d4525a6d88d8ecd11a1b6d98275fa4d6 Signed-off-by: Yulong Pei <yulong.pei@intel.com>
2018-05-04CSIT-992: Add libraries for optimized searchVratko Polak1-9/+9
+ Place the libraries into resources/libraries/python/search/. + Except OptimizedTrexSearch in TrafficGenerator.py + Change traffic generator to support floats for duration and warmup. + Remove explicit type conversions where not needed. + Add robot keywords to performance_utils.robot + for calling the optimized search. + for reporting the resulting values. + for checking the minimal performance has been reached. + for running five second "Traffic should pass with no loss" after the search. - Add methodology documentation in subsequent Change. - Add simulator for testing algorithm correctness in a subsequent Change. - Add tests using the libraries in subsequent Change.
