摘要： An apparatus and method authenticate computed results in a public distributed computing environment without the need for fully recomputing the results. The work unit is operated on by client code that computes one or more partial results along with the completed result. When the results are returned to the server, the server may decide to have a trusted computer system process the same work unit to compute the partial result according to a defined acceptance policy. In addition, the work unit name, user identity and current date are encrypted using a time-sensitive key. Should the server detect a problem with the results (e.g., decrypted work unit name does not match, recomputed partial result does not match), the results may be rejected according to a defined rejection policy. In this manner, it becomes very difficult to fool a server into thinking a work unit has been processed when it has not.

摘要： The present invention is a computer implemented method and system for minimizing contention for a shared resource between a plurality of processes executing computer instructions that are associated with said shared resource. The method analyzes at least one of said processes of computer instructions and determines whether at least one of said processes modifies said shared resource. If at least one of said processes does not modify said shared resource, the method controls access to said shared resource by at least one said process.

摘要： An apparatus, program product, and method perform address translation on a process-local, rather than system-wide, basis in a single-level store virtual memory management system using a plurality of process-local address translation data structures that are individually associated with particular software processes executing on a computer. By performing address translation on a process-by-process basis, many of the security concerns associated with system-wide address translation, e.g., attempting to access a virtual address for memory that has not been allocated for the associated process, are significantly reduced from the standpoint of accessing an address translation data structure, since it can be presumed that all of the information in a process-local address translation data structure was previously authorized for the process when added to the data structure. Relatively simpler and faster security checks can then be performed in association with accessing a process-local address translation data structure to minimize the processing delays associated with such accesses. In addition, with such a configuration, any additional security issues can be handled in additional fault handling processing that is executed less frequently than accesses to address translation data structures, such that such additional security processing has a reduced impact on system performance.

摘要： A conventional bi-endian computer system is enhanced to include mixed-endian circuitry that allows the computer system to dynamically change its endian mode. The mixed-endian computer system can change endian mode on a task by task basis if necessary. The mixed-endian circuitry automatically formats the data in the form expected by the running task, regardless of whether the task expects the data to be in big endian format or in little endian format. The mixed-endian circuitry also formats big and little endian instructions such that they can execute on the same computer system.
