Patent number: 11669406Abstract: A method and system of checkpointing single process application groups and multi-process application groups. In an exemplary embodiment, the method may include creating at least one full checkpoint for each application in an application group, and creating at least one incremental application checkpoint for each application in the application group. Further, each of the at least one incremental application checkpoint may be automatically merged against a corresponding full application checkpoint. Further, checkpointing may be synchronized across all applications in the application group. In the exemplary embodiment, each application may use both fork( ) and exec( ) in any combination.Type: GrantFiled: February 15, 2022Date of Patent: June 6, 2023Assignee: International Business Machines CorporationInventors: Keith Richard Backensto, Allan Havemose

Patent number: 11645163Abstract: A system and method thereof for performing loss-less migration of an application group. In an exemplary embodiment, the system may include a high-availability services module structured for execution in conjunction with an operating system, and one or more computer nodes of a distributed system upon which at least one independent application can be executed upon. The high-availability services module may be structured to be executable on the one or more computer nodes for loss-less migration of the one or more independent applications, and is operable to perform checkpointing of all state in a transport connection.Type: GrantFiled: March 1, 2022Date of Patent: May 9, 2023Assignee: International Business Machines CorporationInventors: Keith Richard Backensto, Allan Havemose

Patent number: 11573868Abstract: A system includes a multi-process application that runs. A multi-process application runs on primary hosts and is checkpointed by a checkpointer comprised of at least one of a kernel-mode checkpointer module and one or more user-space interceptors providing at least one of barrier synchronization, checkpointing thread, resource flushing, and an application virtualization space. Checkpoints may be written to storage and the application restored from said stored checkpoint at a later time. Checkpointing may be incremental using Page Table Entry (PTE) pages and Virtual Memory Areas (VMA) information. Checkpointing is transparent to the application and requires no modification to the application, operating system, networking stack or libraries. In an alternate embodiment the kernel-mode checkpointer is built into the kernel.Type: GrantFiled: April 19, 2022Date of Patent: February 7, 2023Assignee: International Business Machines CorporationInventors: Keith Richard Backensto, Allan Havemose

Patent number: 11487710Abstract: A system and method for storage checkpointing to a group of independent computer applications. The system has a storage disk that stores files; a storage access interface to access the storage disk; and a computer. The computer runs the group of independent computer applications and utilizes the files stored on the storage disk. A file system on the server accesses the files stored on the storage disk. An operating system and at least one device driver can be called by the file system, and at least one buffer buffers first data written to the storage disk and second data read from the storage disk.Type: GrantFiled: December 31, 2020Date of Patent: November 1, 2022Assignee: International Business Machines CorporationInventors: Allan Havemose, Keith Richard Backensto

Patent number: 10394621Abstract: A computer readable medium and method for providing checkpointing to Windows application groups. The checkpointing may be triggered asynchronously using Asynchronous Procedure Calls. The computer readable medium includes computer-executable instructions for execution by a processing system. The computer-executable instructions may be for reviewing one or more command line arguments to determine whether to start at least one of the application groups, and when determining to start the at least one of the application groups, creating a process table in a shared memory to store information about each process of the at least one of the application groups. Further, the instructions may be for registering with a kernel module to create an application group barrier, creating a named pipe for applications of the application group to register and unregister, triggering a checkpoint thread to initiate an application group checkpoint; and launching an initial application of the applications of the application group.Type: GrantFiled: January 10, 2017Date of Patent: August 27, 2019Assignee: OPEN INVENTION NETWORK LLCInventors: Keith Richard Backensto, Allan Havemose

Patent number: 10310754Abstract: A method and system for checkpointing at least one application in an application group. At least one full checkpoint and at least one incremental checkpoint are created for the application in the application group. The at least one incremental application checkpoint is merged against the at least one full application checkpoint, and checkpointing across all applications in the application group is synchronized. A storage checkpoint is taken for at least one of the full checkpoint and the incremental checkpoint, and memory and storage checkpoints are synchronized and consistent.Type: GrantFiled: October 16, 2018Date of Patent: June 4, 2019Assignee: Open Invention Network LLCInventors: Allan Havemose, Keith Richard Backensto

Patent number: 10303554Abstract: A method and system for storage checkpointing of an independent computer application. The independent computer application is launched by a coordinator; and the coordinator installs at least one of an exec interceptor and a fork interceptor. The coordinator also installs at least one file operations interceptor for all file operations and registers the independent computer application with the coordinator. The independent computer application is run and the at least one file operations interceptor is called upon encountering a file operation. The file operations interceptor logs a file event in a file operations database and passes the operation to at least one of a file system, an operating system, at least one or more device drivers, and a storage disk via a storage interface. The file operations interceptor also verifies that the file operation has been issued.Type: GrantFiled: March 8, 2017Date of Patent: May 28, 2019Assignee: OPEN INVENTION NETWORK LLCInventors: Allan Havemose, Keith Richard Backensto
