With some small modifications, the Houdini Ocean Toolkit source code can be used in multithreaded environments.
I created OpenMP variant of the HOT ocean SOP node. On a multicore machine the HOT becomes appreciable faster.
To use the compiled binaries you need the OpenMP libraries (vcomp90.dll) shipped with the Microsoft Visual C++ 2008 Redistributable Package. You can download it from the Microsoft site.
Note: To compile the source with OpenMP enabled you have to turn on the /openmp compiler flag in Visual Studio. Use -fopenmp if you are compiling with the gnu compiler.
