Abstract: A system and method of fault tolerance for distributed applications in a virtualized environment is provided by utilizing Application Agent (AA) of the application Peer-to- Peer (P2P) overlay network. The system and method of the present invention includes the steps of pre-deployment of Virtual Machine (VM) images by executing application by User by invoking the Application Agent (502) and the Application Agent (AA) contact the nearest front end node (504). The Application Agent (AA) request for deployment of virtual machines (VMs) based on task requirement upon receipt of response from front end node (506). Thereafter, a structured overlay network is formed based on virtual machines (VMs) allocated by the front end node (508) and Application Agent (AA) further tracks the status of virtual machines (VMs). Upon successful deployment of virtual machine (VM) images, tasks are spawn during execution of application (404) by replicating computational tasks and data items in DHT (Distributed Hash Table)-based peer to peer (P2P) overlay network with small overhead. Computational tasks are allocated to virtual machines (VMs) (406) and completed task are registered accordingly (408) upon successful allocation of said tasks. Further, the Application Agent (AA) retrieves output data of each completed task. Pre-deployment of virtual machine (VM) images enables Application Agent (AA) to initiate deployment of virtual machines (VMs) based on task requirement and tracking the deployment of VM status. Further, Distributed Hash Tables (DHTs) are leverage to provide long-term fault tolerance which enables remote computational steering without advance reservation.

Abstract: The present invention relates to an apparatus (200) and method (500) for parallel moving adaptive window filtering edit distance computation that utilizes an adaptive window filtering mechanism to accelerate edit distance computation for increased efficiency and shorter times by searching along a critical path that provides a high rate for string similarity matching. The apparatus (200) of the present invention comprising at least one central processing unit (202); at least one storage unit (210); at least one memory module (204, 206); at least one 1/0 hub (212); a plurality of input devices (214); and at least one parallel computation acceleration device (208). The at least one parallel computation acceleration device (208) further comprising at least one match filtering scoping unit (302) which scopes a region of interest of a reference list that is most similar to a search string for matching operation; at least one edit distance adaptive window determining unit (304) to prepare for window setting based on user input and to calculate distance values on critical path. String filtering is performed automatically, wherein strings are sorted based on character offset to ensure all possibilities of matching are covered. Further, a feedback mechanism is provided for the automatic threshold based filtering to initialize the adaptive window setting based on user input to prepare for the threshold-based filtering and to calculate the distance values on the critical path; and to obtain the final distance value to determine whether the comparison is the intended match or not.
