qgate-perf 0.4.1rc11

Performance test generator, part of Quality Gate

QGate-Perf

Performance test generator, part of Quality Gate solution. Key benefits:

• easy performance testing your python code (key parts - init, start, stop, return)
• measure only specific part of your code
• scalability without limits (e.g. from 1 to 1k executors)
• scalability in level of processes and threads (easy way, how to avoid GIL in python)
• sequences for execution and data bulk
• relation to graph generator

Usage

from qgate_perf.parallel_executor import ParallelExecutor
from qgate_perf.parallel_probe import ParallelProbe
from qgate_perf.run_setup import RunSetup
import time

def prf_GIL_impact(run_setup: RunSetup):
    """ Your own function for performance testing, you have to add
    only part INIT, START, STOP and RETURN"""
    
    # INIT - contain executor synchonization, if needed
    probe=ParallelProbe(run_setup)

    while (True):
        # START - probe, only for this specific code part
        probe.start()

        for r in range(run_setup.bulk_row * run_setup.bulk_col):
            time.sleep(0)

        # STOP - probe
        if probe.stop():
            break

    # RETURN - data from probe
    return probe

# Execution setting
generator = ParallelExecutor(prf_GIL_impact,
                             label="GIL_impact",
                             detail_output=True,
                             output_file="prf_gil_impact_01.txt")

# Run setup, with test execution 20 seconds and zero delay before start 
# (without waiting to other executors)
setup=RunSetup(duration_second=20,start_delay=0)

# Run performance test with: 
#  data bulk_list with two data sets 
#    - first has 10 rows and 5 columns as [10, 5]
#    - second has 1000 rows and 50 columns as [1000, 50]
#  executor_list with six executor sets
#    - first line has three executors with 2, 4 and 8 processes each with 2 threads 
#    - second line has three executors with 2, 4 and 8 processes each with 4 threads
generator.run_bulk_executor(bulk_list=[[10, 5], [1000, 50]],
                            executor_list=[[2, 2, '2x thread'], [4, 2, '2x thread'],[8, 2,'2x thread'],
                                           [2, 4, '4x thread'], [4, 4, '4x thread'],[8, 4,'4x thread']],
                            run_setup=setup)

# We made 12 performance tests (two bulk_list x six executor_list) and write 
# outputs to the file 'prf_gil_impact_01.txt'
