i've noticed huge delay when using multiprocessing (with joblib). here simplified version of code: import numpy np joblib import parallel, delayed class matcher(object): def match_all(self, arr1, arr2): args = ((elem1, elem2) elem1 in arr1 elem2 in arr2) results = parallel(n_jobs=-1)(delayed(_parallel_match)(self, e1, e2) e1, e2 in args) # ... def match(self, i1, i2): return i1 == i2 def _parallel_match(m, i1, i2): return m.match(i1, i2) matcher = matcher() matcher.match_all(np.ones(250), np.ones(250)) so if run shown above, takes 30 secs complete , use 200mb. if change parameter n_jobs in parallel , set 1 takes 1.80 secs , barely use 50mb... i suppose has related way pass arguments, haven't found better way it... i'm using python 2.7.9 i have re-written code without using joblib library , works supposed work, although not "beautiful" code: import itertools import multiprocessing import numpy ...

this question has answer here: compile-time , runtime casting c# 2 answers you have these classes shown below: public class { } public class b : { } you cast base class type of derived class a w = (b) new a(); b x = (b) new a(); this not work on run time because cannot convert base class derived class. but why there no compile time error ? why visual studio allowed me reach run-time before throwing error? there 2 types of casts once not allowed when classes have no common base , hence cast have no chance succeed. i.e. 'string' 'int'. such casts caught compiler , cause errors. casts have chance succeed - base derived have reasonable chance succeed. compiler allows such casts. i believe reason why (b)new a() allowed @ compile time if cast guaranteed fail because (b)someobjectoftypea can succeed , new a() 1 of such ...
