摘要： Mechanisms are provided for performing a floating point arithmetic operation in a data processing system. A plurality of floating point operands of the floating point arithmetic operation are received and bits in a mantissa of at least one floating point operand of the plurality of floating point operands are shifted. One or more bits of the mantissa that are shifted outside a range of bits of the mantissa of at least one floating point operand are stored and a vector value is generated based on the stored one or more bits of the mantissa that are shifted outside of the range of bits of the mantissa of the at least one floating point operand. A resultant value is generated for the floating point arithmetic operation based on the vector value and the plurality of floating point operands.

摘要： A system, method, and computer program product for semi-synchronously copying data from a first portion of memory to a second portion of memory are disclosed. The method comprises receiving, in a processor, a call for a semi-synchronous memory copy operation. The semi-synchronous memory copy operation preserves temporal persistence of validity for a virtual source address corresponding to a source location in a memory and a virtual target address corresponding to a target location in the memory by setting a flag bit. The call includes at least the virtual source address, the virtual target address, and an indicator identifying a number of bytes to be copied. The memory copy operation is placed in a queue for execution by a memory controller. The queue is coupled to the memory controller. At least one subsequent instruction is continued to be executed as the subsequent instruction becomes available from an instruction pipeline.

摘要： A computer implemented method, apparatus, and computer usable program code for returning a return code to an error hook in an application using a framework. An identifier and a pass-through are received from the error hook. The error hook is software code in the application. The pass-through is a set of parameters. If the identifier has an active status, a set of framework conditions is retrieved using the identifier. If the set of framework conditions is met, an inject callback is retrieved using the error identifier. The inject callback is called with the error identifier and the pass-through. An inject callback return code is received. If the inject callback return code is an execute return code, the execute return code is returned to the error hook.

摘要： A method, processing node, and computer readable medium for propagating data using mirrored lock caches are disclosed. The method includes coupling a first mirrored lock cache associated with a first processing node to a bus that is communicatively coupled to at least a second mirrored lock cache associated with a second processing node in a multi-processing system. The method further includes receiving, by the first mirrored lock cache, data from a processing node. The data is then mirrored automatically so that the same data is available locally at the second mirrored lock cache for use by the second processing node.

摘要： A method utilizes a multithreaded processor having at least one hardware thread among a plurality of hardware threads that is capable of being selectively activated and deactivated responsive to a control circuit. The control circuit additionally provides the capability of controlling how an inactive thread can be activated after the thread has been deactivated, e.g., by enabling or disabling reactivation in response to an interrupt.

摘要： A data processing system for storing and identifying footprint data in a data processing system enabling automated collection, identification and formatting recovery of footprint data executing on a mainline routine. A footprint area is allocated onto a failure recovery routine stack for use by the mainline routine for storing footprint data. The mainline routine stores footprint data within the first footprint area. The data processing system can then receive a request from a diagnostic tool, where the request includes at least one search parameter. The data processing system can output any footprint data to a diagnostic tool corresponding to the search parameters in the request.
