This should do an almost identical job to the standard DIALS dispersion spotfinder, except faster. It does this via SIMD instructions generated with the intel ispc compiler and execution model.

This is still highly experimental and probably incomplete.

Firstly, you need the ispc compiler available on the path. Otherwise, you should be able to libtbx.pip install [-e] this package without an issue. It needs to be run within libtbx.python because it uses some of the environment variables defined by the TBX dispatchers to work out where the scitbx include files are. These are required because that's all the dials spotfinding infrastructure passes through at the moment.
