摘要： A multiprocessor system which includes automatic workload distribution. As threads execute in the multiprocessor system, an operating system or hypervisor continuously learns the execution characteristics of the threads and saves the information in thread-specific control blocks. The execution characteristics are used to generate thread performance data. As the thread executes, the operating system continuously uses the performance data to steer the thread to a core that will execute the workload most efficiently.

摘要： A system and method for error correction and detection in a memory system. The system includes a memory controller, a plurality of memory modules and a mechanism. The memory modules are in communication with the memory controller and with a plurality of memory devices. The mechanism detects that one of the memory modules has failed possibly coincident with a memory device failure on an other of the memory modules. The mechanism allows the memory system to continue to run unimpaired in the presence of the memory module failure and the memory device failure.

摘要： In a communications channel coupled to multiple duplicated subsystems, a method, interposer and program product are provided for verifying integrity of subsystem responses. Within the communications channel, a first checksum is calculated with receipt of a first response from a first subsystem responsive to a common request, and a second checksum is calculated for a second response of a second subsystem received responsive to the common request. The first checksum and the second checksum are compared, and if matching, only one of the first response and the second response is forwarded from the communications channel as the response to the common request, with the other of the first response and the second response being discarded by the communications channel.

摘要： A system for implementing computer security is provided. The system includes a computer processor and an application configured to execute on the computer processor, the application implementing a method that includes creating a token and populating a payload section of the token with key material and selecting a wrapping method that specifies how the key material is securely bound to key control information. A structure of the key control information in the token is independent of the wrapping method. Implementing computer security also includes wrapping the key material and binding key control information to the key material in the token. The key control information includes information relating to usage and management of the key material.

摘要： A method is described for implementing a trusted computing environment within a data processing system where the data processing system includes a single hardware trusted platform module (TPM). Multiple logical partitions are provided in the data processing system. A unique context is generated for each one of the logical partitions. When one of the logical partitions requires access to the hardware TPM, that partition's context is required to be stored in the hardware TPM. The hardware TPM includes a finite number of storage locations, called context slots, for storing contexts. Each context slot can store one partition's context. Each one of the partitions is associated with one of the limited number of context storage slots in the hardware TPM. At least one of the context slots is simultaneously associated with more than one of the logical partitions. Contexts are swapped into and out of the hardware TPM during runtime of the data processing system so that when ones of the partitions require access to the hardware TPM, their required contexts are currently stored in the hardware TPM.

摘要： Connects a host computer system (such as a mainframe or host server system) to a large multimedia (MM) distribution network having wide scalability without being limited by bandwidth constraints in the host system or in any multimedia controller for controlling "on demand" viewing of movies at a large number of set-top-boxes (STBs) with TV sets. Connected to the host system is a network distribution arrangement comprised of a plurality of multimedia (MM) adapters, each MM adapter containing a plurality of MM controllers, each MM controller being connected to a multiplicity of MM pairs, each MM pair being connected to the network for controlling a direct distribution of movies to a large number of STBs. Each MM pair includes a disk adapter and a network adapter connected by a common MM pair bus for transmitting disk data blocks directly to the STBs. The disk adapter controls and receives data from one or more disk devices. The network adapter sends the disk data to the network. In each MM pair, a pair bus connects the network adapter to transmit data from the disk adapter to the network. Data files (movies) are stored on the disks, and any file can be selected by an STB for transmission to the STB. Data blocks are read directly from the disk to the pair bus and then directly through the network to the requesting STB. Any STB may issue interactive commands to control a data file while it is being received.

摘要： A control process which enables a non-supervisory "using program" (e.g. application programs) to directly interface one or more shared asynchronous hardware facilities in a computer system. Any using program may request the operating system (OS) to set up a "special environment" with an AHF during which the using program can directly issue requests to the AHF for its services. The OS sets up a session for the using program having the "special environment", which specifies restrictions on storage accesses by the AHF for accesses made on behalf of the using program--to insure system data integrity. These restrictions are not changeable by the using program. The "special environment" exists until the session is ended by the using program or by a terminating condition. The "special environment" is tailored to be different among the different using program concurrently using the same AHF, so that the "special environment" of one using program cannot interfere with the "special environment" of another using program. During a session, work requests for any using program are communicated directly to the AHF from the using program, and completion of any work request is communicated directly by the AHF to the using program without any interruption of the using program or OS involvement.
