Abstract
Establishing a data communications connection between a lightweight kernel in a compute node of a parallel computer and an input-output (‘I/O’) node of the parallel computer, including: configuring the compute node with the network address and port value for data communications with the I/O node; establishing a queue pair on the compute node, the queue pair identified by a queue pair number (‘QPN’); receiving, in the I/O node on the parallel computer from the lightweight kernel, a connection request message; establishing by the I/O node on the I/O node a queue pair identified by a QPN for communications with the compute node; and establishing by the I/O node the requested connection by sending to the lightweight kernel a connection reply message.
