hi,

I'm trying to use parallel python to do parametric studies by executing external .exe-files while changing the input file of the .exe. All subroutines and such work properly and give no erros, but when i want to give it to parallel python,  i'm getting following error :

Exception in thread run_local:
Traceback (most recent call last):
  File "C:\Python26\lib\threading.py", line 525, in __bootstrap_inner     self.run()
  File "C:\Python26\lib\threading.py", line 477, in run     self.__target(*self.__args, **self.__kwargs)
  File "C:\Python26\lib\site-packages\pp.py", line 721, in _run_local     job.finalize(sresult)
UnboundLocalError: local variable 'sresult' referenced before assignment

The code i try to run looks as follows :

# first we must make a dictionary of the parameteric we want to do
# and we add the parameters and their values we want to run
dickie = {}
dickie.update({r'serie.amount' : numpy.array([1,2,3,4,5])})
dickie.update({r'omvormer.eff' : numpy.array([6,7,8])})
# now we set everything ready for parallel python
path_list = set_parametric_run(os.getcwd(), dickie)
# initialise the parallel python stuff
ppservers=()
job_server = pp.Server(ncpus = 1, ppservers = ppservers)
# define the inputs
inputs = tuple(path_list)
# and start the simulations
jobs = [(input, job_server.submit(start_parametric_run, (input,), (Popen,), ("os",))) for input in inputs]


Is there anyone who sees what looks wrong in the use of pp ?

Big thanx in advance

R

Your code fails (in the slave script) and than pp fails due to an uninitialized variable in pp code.
