Clean up old memory pools in infiniband node
There are some old buffer pools and functions which I used to run communication of data between nodes. There is no need for these functions anymore since everything is implemented in
ib_write(), and since we are using the buffers allocated by the framework.
@stvogel: before I delete the code, I want to make sure we really don't need it.
Can you think of any scenario where we need other communication than
meta + data (like we have now)?
The only scenario I could think of, is that a node fetches status data of another node with
IBV_WR_RDMA_READ (which reads from the remote memory without remote kernel intervention). This would require the exchange of address/key-pairs with
(For this particular functionality I would reuse the functions, but pools are overkill.)
