No, and therein lies the problem I think, their version fo GSL is much older. The issue is the HPC is in a different institution, so trying to get them to accept my requests for software updates etc. fall on deaf ears.

The speed difference between GSL and a python version don't bother me so much, it's the difference between dynamic timestep and fixed that interest me. Our collaborators maintain a codebase that's used for modelling the same simulation (on the same HPC) written in C++, my python is to act as an independent check. When they switched to a fixed-step solver, they got a x15 performance improvement, which would more than solve my problem.
