NCSHMEM = [integer]
Default: NCSHMEM = 1 

Description: NCSHMEM determines the number of compute cores sharing the memory in MPI in the non-cubic scaling GW routines.


By default no shared memory MPI is in the non-cubic scaling GW routines. For shared memory in the non-cubic scaling GW set NCSHMEM=-1.


Warning: For the openmp version NCHSMEM is not active and shared memory is not used for MPI. In that case the memory is shared between threads.
