Running subProcesses in parallel for mixed external Windows.exe and
Python functions on specified CPUs.
How does a newbie start to make this work?
def startMyFiles(): (not real code, this is only for explaining
my problem)
import OS
import time
import sys
import subprocess
from win32event import WaitForSingleObject, WAIT_TIMEOUT
from win32api import TerminateProcess
import myNewPythonCodeReadWriteSQLite # my new module
import myNewPythonCodeReadSQLiteShowMatPlotLib # my new module
"show" here? or "draw"?
# these two Windows executables should run in sequence and on CPU_2
# but as a group of 2 run in parallel with the next 2 groups
p11 = subprocess.Popen("C:\myDdeServer.exe ")
# loads DDE Server
p12 = subprocess.Popen("c:\ddeClicks.ahk ")
# starts dde server with clicks and keyboard strokes
# these two should run in sequence on CPU_3
# but as a group of 2 run in parallel with the next
group
p21 = subprocess.Popen("C:\showRawData.xlsm ")
# loads Excel spreadsheet to show incoming data in real time
p22 = subprocess.Popen("c:\xlsClicks.ahk ")
# send mouse clicks and keyboard strokes to start Excel
# these two should run in sequence on
CPU_4
# but as a group of 2 run in parallel with the prior 2
groups
p31 = subprocess.Popen("pw5.exe c:\legacyScript.was")
# loads legacy code to read and write from spreadsheet to SQLite
data base
p32 = subprocess.Popen("c:\wasClicks.ahk ")
# sends mouse clicks and keyboard strokes to start legacy code
#this new Python code runs in parallel for ever on CPU_2
readWriteSQLiteDef() # from
myNewPythonCodeReadWriteSQLite Module
# runs for ever to read and write and refresh SQLite in parallel
what subprocess?
#this new Python code runs in parallel for ever on
CPU_3
readSQLiteShowMatPlotLibDef() # from
myNewPythonCodeReadSQLiteShowMatPlotLib Module
# runs for ever to refresh graphics from SQLite what subprocess?
