Re: How to add a C code to NAMD properly?

To add to Haochuan's remark: the best way to do it will vastly depend on
what you are calculating, and what it depends on: positions? velocities?
forces? few atoms, many atoms, all atoms? box size? pressure? Is it an
expensive calculation? Do you need to parallelize it?
