Methods And Apparatus For Virtual Machine Recovery

View page
US Patent:
20130332771, Dec 12, 2013
Filed:
Jun 11, 2012
Appl. No.:
13/493304
Inventors:
Valentina Salapura - Chappaqua NY, US
Richard E. Harper - Chapel Hill NC, US
Kyung D. Ryu - New City NY, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 11/14
US Classification:
714 15, 714E11117
Abstract:
Methods and apparatus for recovery of virtual machine failure. A succession of data images is captured, with each of the data images comprising an operating system of the virtual machine. The data images are images of data elements chosen based at least in part on their suitability for virtual machine restoration. Upon detection of a virtual machine failure, an attempt is made to restore the virtual machine using the highest ranked. If the attempt fails, further attempts are made using lower ranked data images, until an attempt is successful or all available data images have been used.

Checkpointing Using Compute Node Health Information

View page
US Patent:
20190196920, Jun 27, 2019
Filed:
Dec 22, 2017
Appl. No.:
15/853343
Inventors:
- Armonk NY, US
Yoonho PARK - Chappaqua NY, US
Chen-Yong CHER - Port Chester NY, US
Bryan ROSENBURG - Cortlandt Manor NY, US
Kyung RYU - New City NY, US
International Classification:
G06F 11/14
Abstract:
A method is disclosed, as well as an associated apparatus and computer program product, for checkpointing using a plurality of communicatively coupled compute nodes. The method comprises acquiring health information for a first node of the plurality of compute nodes, and determining a first failure probability for the first node using the health information. The first failure probability corresponds to a predetermined time interval. The method further comprises selecting a second node of the plurality of compute nodes as a partner node for the first node. The second node has a second failure probability for the time interval. A composite failure probability of the first node and the second node is less than the first failure probability. The method further comprises copying checkpoint information from the first node to the partner node.

Network Resiliency Through Memory Health Monitoring And Proactive Management

View page
US Patent:
20180097712, Apr 5, 2018
Filed:
Nov 19, 2017
Appl. No.:
15/817254
Inventors:
- Armonk NY, US
Chen-Yong Cher - Port Chester NY, US
Yoonho Park - Chappaqua NY, US
Bryan S. Rosenburg - Cortlandt Manor NY, US
Kyung D. Ryu - New City NY, US
International Classification:
H04L 12/26
H04L 12/24
Abstract:
A method for managing a network queue memory includes receiving sensor information about the network queue memory, predicting a memory failure in the network queue memory based on the sensor information, and outputting a notification through a plurality of nodes forming a network and using the network queue memory, the notification configuring communications between the nodes.

Method And Apparatus For Selective And Power-Aware Memory Error Protection And Memory Management

View page
US Patent:
20160301428, Oct 13, 2016
Filed:
Apr 11, 2015
Appl. No.:
14/684368
Inventors:
- Armonk NY, US
Chen-Yong Cher - Port Chester NY, US
Yoonho Park - Chappaqua NY, US
Bryan S. Rosenburg - Cortlandt Manor NY, US
Kyung D. Ryu - New City NY, US
International Classification:
H03M 13/35
G06F 11/10
Abstract:
A method for providing selective memory error protection responsive to a predictable failure notification associated with at least one portion of a memory in a computing system includes: obtaining an active error correcting code (ECC) configuration corresponding to the portion of the memory; determining whether the active ECC configuration is sufficient to correct at least one error in the portion of the memory affected by the predictable failure notification; when the active ECC configuration is insufficient to correct the error, determining whether data corruption can be tolerated by an application running on the computing system; when data corruption cannot be tolerated by the application, determining whether a stronger ECC level is available and, if a stronger ECC level is available, increasing a strength of the active ECC configuration; and when data corruption can be tolerated, performing page reassignment and aggregation of non-critical data.

US Patent:
20150227426, Aug 13, 2015

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 11/14
G06F 11/00
Abstract:
A method for selective duplication of subtasks in a high-performance computing system includes: monitoring a health status of one or more nodes in a high-performance computing system, where one or more subtasks of a parallel task execute on the one or more nodes; identifying one or more nodes as having a likelihood of failure which exceeds a first prescribed threshold; selectively duplicating the one or more subtasks that execute on the one or more nodes having a likelihood of failure which exceeds the first prescribed threshold; and notifying a messaging library that one or more subtasks were duplicated.
