Patent number: 11271838Abstract: Embodiments include method, systems and computer program products for timing synchronization. Aspects include sending to a remote system a first base packet, the first base packet is sent at a first send event time and then recording the first send event time in a memory. Aspects also include sending to the remote system a second base packet, wherein the payload comprises instructions for the remote computing system and receiving a first remote packet, wherein a payload comprises a first received time indicating a time the first base packet was received. Aspects then include recording the first received time and recording a second received time, wherein the second received time indicates a time the first remote packet was received by the base system. Aspects include receiving a second remote packet, wherein a payload comprises a second sent time indicating a time the first remote packet was sent.Type: GrantFiled: January 13, 2017Date of Patent: March 8, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Donald Crabtree, Richard K.

Patent number: 10659376Abstract: A computer-implemented method for message handling between a receiver and a sender of a throttling system is provided. The computer-implemented method includes receiving a first message that includes a completion queue element by the receiver from the sender. The computer-implemented method includes detecting that a number of outstanding completion queue elements in a completion queue meets or exceeds a high mark and instructing the sender to enter a throttle mode. The computer-implemented method includes receiving a second message without a completion queue element by the receiver from the sender. The computer-implemented method includes detecting that the number of the outstanding completion queue elements in the completion queue meets or is below a low mark and instructing the sender to exit the throttle mode.Type: GrantFiled: May 18, 2017Date of Patent: May 19, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Scott E. Davies, Richard K. Errickson, Jinghong Ma, Andrew W. Piechowski, Peter K. Szwed, Ambrose A. Verdibello, Jr.

Patent number: 10616115Abstract: Embodiments are directed to a computer system for managing data transfer. The computer system includes a memory, a processor communicatively coupled to the memory, a send component and a receive component having a message queue and a controller. A single link interface communicatively couples the send component to the receive component. The single link interface includes a mainline channel and a sideband channel, and the computer system is configured to perform a method. The method includes transmitting mainline channel messages over the mainline channel from the send component to the receive component. The method further includes transmitting sideband channel messages over the sideband channel from the send component to the message queue of the receive component. The method further includes utilizing the controller to control a flow of the sideband channel messages to the message queue without relying on sending feedback to the send component about the flow.Type: GrantFiled: November 1, 2017Date of Patent: April 7, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Richard K. Errickson, Thomas A. Gregg, Leonard W. Helmer, Jr., Michael P. Lyons, Kulwant M. Pandey, Peter K. Szwed

Patent number: 10089171Abstract: A method, computer program product, and system to control event logging and error recovery in a system including adapters, ports, and channels are described. The method includes storing a recovery threshold for each event type among a plurality of event types and storing a level-specific logging threshold for each event type, implementing event handlers for each of the channels, the ports, and the adapters of the system, and implementing a threshold manager for the events identified by the event handlers based on the level-specific logging threshold and the recovery threshold for each of the respective event types of each of the events. For any identified event corresponding with a given event type, the implementing the threshold manager includes considering the recovery threshold and the level-specific logging threshold at every level regardless of a level at which the identified event is identified.Type: GrantFiled: August 31, 2016Date of Patent: October 2, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Richard K.
