Shankar,
I am trying to dump the particle_positions to a file. Here is my extremely inefficient script...
It's slow because you're writing to a text file. It would be faster to write to binary. However, numpy's 'tofile' command will probably be faster than what you've got, and it can write to a text file: http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.tofile.htm... It would be something like: In [1]: import numpy as na In [2]: I = na.random.random(9) In [3]: I.tofile('I.dat', sep = " ", format="%1.5e\n") %cat I.dat 6.31265e-01 7.37249e-01 8.32688e-02 4.91137e-01 6.83693e-01 1.89788e-01 6.74790e-01 9.72683e-01 9.24882e-01 I also suggest trying to save data using h5py, if they're going to be large fields.
