Abstract: A method of dynamic parallelization for programs in systems having at least two processors includes examining computer code of a program to be performed by the system, determining a largest possible parallel region in the computer code, classifying data to be used by the program based on a usage pattern and initiating multiple, concurrent processes to perform the program. The multiple, concurrent processes ensure a baseline performance that is at least as efficient as a sequential performance of the computer code.

Abstract: Objects of an object set stored in an archive may be randomly accessed using the addresses of the objects stored in the archive. However, archives often fail to enable random access to the data within an object, without accessing other portions of the object, due to the variable compression of respective segments of the object. Random-access capabilities within the objects may be provided by segmenting the object into segments of a segment size, generating a block map specifying the block sizes of respective blocks corresponding to respective segments of the objects, and storing the block map in the archive as an object of the object set. Additionally, hashcodes may be calculated respective blocks and included in the block map in order to expose alterations of respective blocks, and/or to update an archive to an updated version of the archive by comparing the hashcodes and retrieving and substituting the updated blocks.

Abstract: Documents distributed in parallel are processed. One or more digital document packages are received, where each digital document package includes a content portion and an identity-verification code (IVC) verifying an identity of a source from which the digital document package is received. Each IVC may be a private-key encryption of a content-verification code hashed from the content portion of each digital document package. A master digital document package is created, which includes a master content portion equivalent to the content portion in each unmodified digital document package, and one or more different IVCs, each IVC obtained from a digital document package received from a different source.
