Is it possible to use CVXOPT in parallel (using e.g. the Python multiprocessing package)? In my attempts to do so I Python always crashes the moment I call any CVXOPT optimizer in a parallelized for loop. I'd be happy to provide an example if desired.

What platform are you using? I'd be happy to look into it if you provide a small example.

Thanks so much! I am using Mac OSX Mavericks. Attached is a simple Python program that brings about the crash. Running it on Linux works fine though! So I'm guessing it has to do with Apple's implementation of LAPACK/BLAS...

Ahh. Nevermind. It is a numpy problem; has nothing to do with CVXOPT as far as I can tell.
