No, the memory is local memory for your process which you can allocate 
using malloc (or even static memory) thay you registered.

You can read the buffers (that remote nodes RDMA Write to) using 
memcpy/pointer access or any other way that you can use memory buffers 
in your process.

After the RDMA Write ands and the data is placed in the remote buffer, 
one can treat the local buffer as IB wasn't used ....
