摘要： A non-disruptive unassignment of an address from a fabric responsive to a request from a channel adapter. A logout command requests the fabric to unassign an address. The status of the address is thereby changed from active to unassigned and an acknowledgment sent back to the channel adapter.

摘要： An exemplary embodiment of the invention relates to a method, system, and storage medium for resolving contention issues by a channel in a fibre optic switch environment that occur during channel program execution. The method comprises a channel receiving a status packet indicating a device is no longer busy. The method also includes specifying whether the channel intends to re-initiate a channel program that previously resulted in the device busy status. If the channel does not intend to re-initiate the channel program, a first combination of bits in a re-initiate field of a status-acceptance packet are set which indicate that the channel will take no further action. If the channel intends to re-initiate the channel program, a second combination of bits in the re-initiate field of the status-acceptance packet are set, indicating that the channel will re-initiate the channel program. The method further includes transmitting the status-acceptance packet to a control unit. The invention also includes a system and a storage medium.

摘要： State information is communicated in a network to more efficiently utilize network resources. A first node forms a single extended query requesting state information from at least one logical image of a second node. The extended query is a single query requesting state information for multiple logical images of the first node. The requested state information includes the status of logical paths previously established between the multiple logical images of the first node and the at least one logical image of the second node. Upon sending the extended query to the second node, a single extended response can be formed at the second node having the requested state information.

摘要： The present invention provides for a method of transferring information in a network computing system environment. The network environment includes a main storage coupled to a channel subsystem with a plurality of channels which is in processing communication with a control unit capable of coupling to a plurality of input/output devices. At first the packets of data are sent concurrently to and from the main storage. Next execution of certain channel functions are transferred to the control unit so that certain commands can be combined with the data packets in one sequence. Finally only one start data command and only one end command notification needs to be sent before and after a plurality of data packets is transferred respectively. In one embodiment another method is employed in the same network computing system environment having the steps of: fetching said command from said main storage; fetching associated data from said main storage; and transferring said fetched command along with said fetched associated data to said control unit.

摘要： A method of data processing includes a processor of a data processing system executing a controlling thread of a program and detecting occurrence of a particular asynchronous event during execution of the controlling thread of the program. In response to occurrence of the particular asynchronous event during execution of the controlling thread of the program, the processor initiates execution of an assist thread of the program such that the processor simultaneously executes the assist thread and controlling thread of the program.

摘要： A performance monitoring technique provides task-switch immune operation without requiring storage and retrieval of the performance monitor state when a task switch occurs. When a hypervisor signals that a task is being resumed, it provides an indication, which starts a delay timer. The delay timer is resettable in case a predetermined time period has not elapsed when the next task switch occurs. After the delay timer expires, analysis of the performance monitor measurements is resumed, which prevents an initial state or a state remaining from a previous task from corrupting the performance monitoring results. The performance monitor may be or include an execution trace unit that collects taken branches in a current trace and may use branch prediction success to determine whether to collect a predicted and taken branch instruction in a current trace or to start a new segment when the branch resolves in a non-predicted direction.

摘要： A technique for indicating a safe shared resource condition with respect to a disabled thread provides a mechanism for providing a fast indication to other hardware threads that a temporarily disabled thread can no longer impact shared resources, such as shared special-purpose registers and translation look-aside buffers within the processor core. Signals from pipelines within the core indicates whether any of the instructions pending in the pipeline impact the shared resources and if not, then the thread disable status is presented to the other threads via a state change in a thread status register. Upon receiving an indication that a particular hardware thread is to be disabled, control logic halts the dispatch of instructions for the particular hardware thread, and then waits until any indication that a shared resource is impacted by an instruction has cleared. Then the control logic updates the thread status to indicate the thread is disabled.

摘要： Techniques for simulating exclusive use of a processor core amongst multiple logical partitions (LPARs) include providing hardware thread-dependent status information in response to access requests by the LPARs that is reflective of exclusive use of the processor by the LPAR accessing the hardware thread-dependent information. The information returned in response to the access requests is transformed if the requestor is a program executing at a privilege level lower than the hypervisor privilege level, so that each logical partition views the processor as though it has exclusive use of the processor. The techniques may be implemented by a logical circuit block within the processor core that transforms the hardware thread-specific information to a logical representation of the hardware thread-specific information or the transformation may be performed by program instructions of an interrupt handler that traps access to the physical register containing the information.

摘要： A system for authenticating a requesting entity in a subnet communications environment includes determining a client identification of a client node associated with the requesting entity, and determining whether the requesting entity associated with the client node is acting in a supervisor capacity. A key to the requesting entity is returned from a resource provider node upon determining that the client identification of the client node indicates that the client node is permitted to access one or more resources of the provider node, and that the client node is acting in a supervisor capacity.
