PyPy is an alternative implementation of Python, and by defaiult uses a minimark garbage collector. https://pypy.readthedocs.org/en/release-2.4.x/garbage_collection.html You will have to write your own bindings for the CPLEX C library, though, using cffi. http://cffi.readthedocs.org/en/latest/overview.html (since the bindings you have assume the CPython ref counting gc). But if your C program is itself using too much memory, then this probably won't help. Discuss this more on pypy-dev@python.org or the #pypy channel on freenode. People on pypy-dev would appreciate not getting libreoffice spreadsheet attachments but just the figures as plain text. Laura
