public subroutine mus_init_longBuffers(comm, pattern)

Wrapper around the actual communication, to avoid copy-in, copy-out by the Intel compiler. (At least the intel compiler on pigeon (v12.0) seems to do copying here, if a sub-array is passed to an assumed size dummy argument. Therefore we use this wrapping with an assumed shape dummy argument, so we can pass a complete field to the actual exchange which has an assumed size argument, without copying complete state field around, just for communication. Ugly, but it doesn't seem to have an impact on performance, and right it seems to be the most suitable solution.

Copy the element position in send and recv buffer to pos array in long type buffer
