Patent number: 8607199Abstract: A technique for debugging code during runtime includes providing, from an outside process, a trigger to a daemon. In this case, the trigger is associated with a registered callback function. The trigger is then provided, from the daemon, to one or more designated tasks of a job. The registered callback function (that is associated with the trigger) is then executed by the one or more designated tasks. Execution results of the executed registered callback function are then returned (from the one or more designated tasks) to the daemon.Type: GrantFiled: December 16, 2009Date of Patent: December 10, 2013Assignee: International Business Machines CorporationInventors: Chulho Kim, Hanhong Xue, Tsai-Yang Jea, Hung Q.

Publication number: 20130232262Abstract: A message flow controller limits a process from passing a new message in a reliable message passing layer from a source node to at least one destination node while a total number of in-flight messages for the process meets a first level limit. The message flow controller limits the new message from passing from the source node to a particular destination node from among a plurality of destination nodes while a total number of in-flight messages to the particular destination node meets a second level limit. Responsive to the total number of in-flight messages to the particular destination node not meeting the second level limit, the message flow controller only sends a new packet from among at least one packet for the new message to the particular destination node while a total number of in-flight packets for the new message is less than a third level limit.Type: ApplicationFiled: April 5, 2013Publication date: September 5, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: UMAN CHAN, DERYCK X.

Publication number: 20130173738Abstract: In a distributed computing system that includes compute nodes that include computer memory, globally accessible memory space is administered by: for each compute node: mapping a memory region of a predefined size beginning at a predefined address; executing one or more memory management operations within the memory region, including, for each memory management operation executed within the memory region: executing the operation collectively by all compute nodes, where the operation includes a specification of one or more parameters and the parameters are the same across all compute nodes; receiving, by each compute node from a deterministic memory management module in response to the memory management operation, a return value, where the return value is the same across all compute nodes; entering, by each compute node after local completion of the memory management operation, a barrier; and when all compute nodes have entered the barrier, resuming execution.Type: ApplicationFiled: January 4, 2012Publication date: July 4, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Tsai-Yang Jea, Yuan Yuan Nie

Publication number: 20130152101Abstract: A job may be divided into multiple tasks that may execute in parallel on one or more compute nodes. The tasks executing on the same compute node may be coordinated using barrier synchronization. However, to perform barrier synchronization, the tasks use (or attach) to a barrier synchronization register which establishes a common checkpoint for each of the tasks. A leader task may use a shared memory region to publish to follower tasks the location of the barrier synchronization register—i.e., a barrier synchronization register ID. The follower tasks may then monitor the shared memory to determine the barrier synchronization register ID. The leader task may also use a count to ensure all the tasks attach to the BSR. This advantageously avoids any task-to-task communication which may reduce overhead and improve performance.Type: ApplicationFiled: December 8, 2011Publication date: June 13, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Tsai-Yang Jea, William P.

Patent number: 8249314Abstract: A biometric representation of a fingerprint from which the original biometric cannot be recovered (privacy) and which can be canceled and reissued. For example, based on an individual's token, the representation can be scrambled uniquely to the individual. From the scrambled biometric representation it is not feasible to reconstruct the biometric and if the representation is compromised, a new one is easily issued. In another aspect, if a biometric can be represented by some other one-dimensional structure, a distance or similarity measure is defined to compare biometrics. Verification decisions can be made based on the distance between or similarity of biometrics.Type: GrantFiled: August 7, 2008Date of Patent: August 21, 2012Assignee: International Business Machines CorporationInventors: Rudolf M.

Patent number: 8135911Abstract: A method, system, and computer program product are provided for managing a cache. A region to be stored within the cache is received. The cache includes multiple regions and each of the regions is defined by memory ranges having a starting index and an ending index. The region that has been received is stored in the cache in accordance with a cache invariant. The cache invariant guarantees that at any given point in time the regions in the cache are stored in a given order and none of the regions are completely contained within any other of the regions.Type: GrantFiled: October 21, 2008Date of Patent: March 13, 2012Assignee: International Business Machines CorporationInventors: Uman Chan, Deryck X.

Patent number: 7138611Abstract: A heating structure and its temperature control method having therein a heat generating line and a controller. The heat generating line includes a PTC element and a short circuit line serially connected having an insulating fusible layer separating them. When a user sets a heating temperature, electric current is conducted to heat the PTC element, alternative string wave signals input into an AC phase shaping circuit and an AC phase delay shaping circuit are converted into square wave signals; and by measuring with a microprocessor at a given time the phase shift between the two phase shaping circuits to control the switch of a trigger circuit, the PTC element can keep on heating or reduce its temperature to therefore keep the heat generating line at a predetermined working temperature. The structure is applicable to heat generating devices such as electric ovens and heating blankets etc.Type: GrantFiled: March 2, 2005Date of Patent: November 21, 2006Inventor: Shuh-Tsai Yang
