Patent number: 9104493Abstract: A system and method of managing a cluster of distributed machines is described. A cluster manager receives status updates regarding tasks running on each machine in the cluster from a task tracker running on the machine. The cluster manager receives resource requests from a job tracker created by a client wishing to run a job in the cluster. The cluster manager is responsible for implementing push-based fair scheduling of resources to the job trackers. The job tracker is responsible for running tasks for one job in the resource identified by the cluster manager. In one embodiment, the job tracker can run in the client for small jobs and in the cluster for larger jobs. The cluster manager can also be restarted, for example, for software updates without restraining the cluster.Type: GrantFiled: November 6, 2012Date of Patent: August 11, 2015Assignee: FACEBOOK, INC.Inventors: Dmytro Molkov, Ramkumar Venkat Vadali, Chun-Yang Chen, Joydeep Sen Sarma

Patent number: 8442563Abstract: Automated text-based messaging interaction using natural language understanding technologies enables text-based messages to be received from users and interpreted by a self-service application platform so that the self-service application platform can respond to the text-based messages in an automated manner. The characters and strings of characters contained within the text message are interpreted to extract words, which are then processed using a natural language understanding engine to determine the content of the text-based message. The content is used to generate a response message from static and/or dynamic grammars to automate the process of interacting with a user via text-based messages. Multiple text-based message formats are supported, including text messages transmitted using Short Messaging Service (SMS), instant messaging, chat, and e-mail.Type: GrantFiled: December 11, 2009Date of Patent: May 14, 2013Assignee: Avaya Inc.Inventors: Chun-Yang Chen, Russell Gulli, Christopher Passaretti, Chingfa Wu, Stephen Buckley
