Abstract: A system, method and computer program product to execute a first and a second work-group, and compare the signature variables of the first work-group to the signature variables of the second work-group via a synchronization mechanism. The first and the second work-group are mapped to an identifier via software. This mapping ensures that the first and second work-groups execute exactly the same data for exactly the same code without changes to the underlying hardware. By executing the first and second work-groups independently, the underlying computation of the first and second work-groups can be verified. Moreover, system performance is not substantially affected because the execution results of the first and second work-groups are compared only at specified comparison points.

Abstract: A system and method for identifying optimal system architectures for a reference application are provided. The system and method comprise executing a reference application and a plurality of test applications on a current system architecture and sampling performance data for each of the applications. The performance data is used to compute an application signature for each application. A similarity element is derived from the application signatures that illustrates the similarity between each application and every other application. Using a similarity threshold and an algorithm, a subset of test applications that are similar to the reference application are derived.

Abstract: The present disclosure describes systems and methods for hierarchical, iterative backup and restoration of files in a hierarchy. Upon backup of a new or modified file, an identification file is created with entries identifying the new or modified file and current versions of all other files in the same directory. The identification file may be stored on the local system and marked for backup. This triggers standard backup routines, such that the identification file is then backed up as if it were a new file in the parent directory. Accordingly, a second identification file is created with entries identifying the first identification file (and thus the child directory) as well as any other current versions of files in the parent directory and identification files for other child directories. This process is iteratively repeated, climbing through the directory structure, until reaching a top-most or root folder.
Abstract translation: 本公开描述了用于层次结构中的文件的分级，迭代备份和恢复的系统和方法。 在备份新的或修改的文件时，将创建一个标识文件，其条目标识新的或修改的文件以及同一目录中所有其他文件的当前版本。 识别文件可能存储在本地系统上并进行备份。 这将触发标准备份例程，以便将身份文件备份为父目录中的新文件。 因此，创建具有标识第一标识文件（以及因此子目录）的条目以及父目录中的任何其它当前版本的文件以及其他子目录的标识文件的第二标识文件。 这个过程被迭代地重复，爬过目录结构，直到到达最顶层或根文件夹。

Abstract: A system for processing data comprises a deduplicating system, an interface, and a processor. The deduplicating system stores a copy of data stored in a data storage system by storing a set of segments that is able to reconstruct the data stored in the data storage system. The interface receives an indication to revert data stored in the data storage system to a state of data at a snapshot time stored in the deduplicating system. The processor is configured to determine a subset of the data stored in the data storage system that has changed between the data stored in the data storage system and the state of data at the snapshot time stored in the deduplicating system using a first list of fingerprints associated with the data stored on the data storage system and a second list of fingerprints associated with the state of data at the snapshot time stored in the deduplicating system.
