No, the memory is local memory for your process which you can allocate
using malloc (or even static memory) thay you registered.
Can I access that memory directly with pointers in the case of a node
accessing its own memory location? Are local access RDMA operations
efficient?
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 ....
