Abstract: A trusted computing environment may be dynamically certified by providing a selectable boot option that controls running a loadable boot image in one of a test mode and a production mode. The test mode may automate running a processing standard validation test to obtain a processing standard validation test result. Responsive to running the processing standard validation test with a successful test result, a record indicating the successful test result and the loadable boot image is stored within the trusted computing environment, utilizing a certification process. Responsive to running the production mode, the trusted computing environment and the loadable boot image may be loaded.

Abstract: A data backup and restore method and system for a multiple computer system environment is provided. The method/system comprises an automated approach for backing up and if necessary restoring computer system data from a first computer system to an auxiliary storage pool of a second computer system. At the first computer system, a renaming of system data to be backed up is accomplished such that the renamed system data designates the first computer system as the source system of the system data and comprises a name different from any name of system data at the second computer system. The renamed system data is then backup stored by the first computer system to the auxiliary storage pool of the second computer system. Multiple computer systems in the multisystem environment can be backed up to the same target computer system, either to the same auxiliary storage pool or to different auxiliary storage pools. Partial or complete restore of the backed up system data is also discussed.

Abstract: A stride enhancer provides high memory bandwidth on strides greater than one and minimizes requests to memory. The basic memory module (BSM) design uses line fetches as the basic cache complex fetch mechanism and allows operation of the BSM to be stride independent. In the preferred implementation, the BSM has two fetch modes; a normal mode and a line fetch mode. In the normal mode, a quadword (QW) is fetched as in the conventional design. In the line fetch mode, all double words (DWs) within the referenced line are returned to the storage control element (SCE) at two DWs per cycle for strides one through eight (twice the conventional bandwidth) or at least one DW per cycle for all other strides (equal to the conventional bandwidth). This is accomplished with two DW busses rather than a single QW bus and by interleaving DW storage locations within the BSM. In line fetch mode for strides one through eight, DWs are read out according to the stride on the two DW busses.

Abstract: A memory system and a unique memory chip is disclosed wherein multiple islands on a chip can be separately accessed by separate island controllers whereby concurrent use of the several islands or arrays on a chip can be achieved.
