Are there any limitations on I/O that can be performed by migrated processes
Usually, remote I/O done by migrated processes on remote nodes
is performed via the respective home-node of each process.
While this does not limit the allowed operations, it may slow-down
such processes. Thus, if the amount of I/O is significant, it will
often cause the process to migrate back to its home-node.
Note that the amount and frequency of I/O is taken into account and
weighted against other considerations in making such a decision.
The direct-communication (migratable socket) can reduce this slow-down
affect for I/O between communicating processes.
