POPython and C++ script interaction
text
Body
copied!<p>I am trying to optimize the interaction between two scripts I have. Two things I thought of are the c++ program not terminating unless you manually kill it, or generating all info in python before feeding it to c++.</p> <p>Explanation of the problem:</p> <p>What the scripts do: C++ program (not made by me, and I can't program in c++ very well): takes a 7 number array and returns a single number, simple. Python script (mine, and I can program a bit in python): generates those 7 number arrays, feeds them to the c++ program, waits for an answer and adds it to a list. It then makes the next array. </p> <p>In theory, this works. However, as it is right now, it opens and closes the c++ program for each call. For one array that is no problem, but I'm trying to upscale to 25k arrays, and in the future to 6+ million arrays. Obviously it is then no longer feasible to open/close it each time, especially since the c++ program first has to load a 130mb VCD file to function.</p> <p>Two options I thought of myself were to generate all arrays first in python, then feed them to the c++ program and then analyze all results. However, I wouldn't know how to do this with 6M arrays. It is not important however that the results I get back are in the same order as the arrays I feed in.</p> <p>Second option I thought of was to make the c++ program not quit after each call. I can't program in c++ though so I don't know if this is possible, keeping it 'alive' so you can just feed arrays into it at times and get an answer.</p> <p>(Note: I cannot program in anything else than python, and want to do this project in python. The c++ program cannot be translated to python for speed reasons.)</p> <p>Thanks in advance, Max.</p>
