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
First Claim
1. A method of 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, the method comprising;
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, the connection request message including a type field identifying the message as a connection request message, a data communications network address for the compute node, a torus address for the compute node, a port value for the lightweight kernel, a port value for the I/O node, and a QPN for the compute node;
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, the connection reply message including a type field identifying the message as a connection reply message, the data communications network address of the compute node, the torus address of the compute node, the port value for the lightweight kernel, the port value of the I/O node, the QPN for the compute node, and the QPN for the I/O node.

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.
