init_sendBuffers Subroutine

private subroutine init_sendBuffers(send, remoteHalos, neigh, pattern, scheme, nSize)

Create the communication buffers

Receive buffers were before created. Now receive the buffers as send buffers from the remote processes. Assign the positions, where to fetch from and where to save to Solver specific part to identify the actual data locations to send use within the communication buffers.

Access to state array: SAVE

Why? Because we need to work on the pdfs on which the compute kernel was working. The kernel stored to SAVE All actions taking place on the state array after the kernel need to be performed with SAVE access
