摘要： Systems and methods for scanning ports for work are provided. One system includes one or more processors, multiple ports, a first tracking mechanism, and a second tracking mechanism for tracking high priority work and low priority work, respectively. The processor(s) is/are configured to perform the below method. One method includes scanning the ports, finding high priority work on a port, and accepting or declining the high priority work. The method further includes changing a designation of the processor to TRUE in the first tracking mechanism if the processor accepts the high priority work such that the processor is allowed to perform the high priority work on the port. Also provided are computer storage mediums including computer code for performing the above method.

摘要： For movement of partial data segments within a computing storage environment having lower and higher levels of cache by a processor, a whole data segment containing one of the partial data segments is promoted to both the lower and higher levels of cache. Requested data of the whole data segment is split and positioned at a Most Recently Used (MRU) portion of a demotion queue of the higher level of cache. Unrequested data of the whole data segment is split and positioned at a Least Recently Used (LRU) portion of the demotion queue of the higher level of cache. The unrequested data is pinned in place until a write of the whole data segment to the lower level of cache completes.

摘要： A method for efficiently using a large secondary cache is disclosed herein. In certain embodiments, such a method may include accumulating, in a secondary cache, a plurality of data tracks. These data tracks may include modified data and/or unmodified data. The method may determine if a subset of the plurality of data tracks makes up a full stride. In the event the subset makes up a full stride, the method may destage the subset from the secondary cache. By destaging full strides, the method reduces the number of disk operations that are required to destage data from the secondary cache. A corresponding computer program product and apparatus are also disclosed herein.

摘要： One embodiment of an adapter card in accordance with the invention includes a circuit board connectable to a motherboard of a computer system. A logic chip is connected to the circuit board to provide functionality to the adapter card. One or more programmable devices are connected to the circuit board and store data read by the logic chip upon initialization. This data may include first character data to program the logic chip to have a first character and second character data to program the logic chip to have a second character. A switching mechanism is provided to switch between the first and second character data in response to an external input, thereby causing the logic chip to read one of the first and second character data.

摘要： Updating code of a single processor in a multi-processor system includes halting transactions processed by a first processor in the system and processing of transactions by a second processor in the system are maintained. The first processor then receives new code and an operating system running on the first processor is terminated whereby all processes and threads being executed by the first processor are terminated. Execution of a self-reset of the first processor is commenced and interrupts associated with the first processor are disabled. Only those system resources exclusively associated with the first processor are reset, and memory transactions associated with the first processor are disabled. An image of the new code is copied into memory associated with the first processor, registers associated with the first processor are reset and the new code is booted by the first processor.

摘要： Provided are a computer program product, system, and method for managing data in a first cache and a second cache. A reference count is maintained in the second cache for the page when the page is stored in the second cache. It is determined that the page is to be promoted from the second cache to the first cache. In response to determining that the reference count is greater than zero, the page is added to a Least Recently Used (LRU) end of an LRU list in the first cache. In response to determining that the reference count is less than or equal to zero, the page is added to a Most Recently Used (LRU) end of the LRU list in the first cache.

摘要： A method to enable a user mode process to operate in a privileged execution mode is disclosed. Applicants' method provides an operating system comprising a privileged execution mode and a non-privileged execution mode, and a plurality of user mode strings operating in the non-privileged execution mode. The computing device receives a request from a first user mode string to operate in the privileged execution mode to perform one or more designated tasks. Applicants' method authorizes the first user mode string to operate in the privileged execution mode, and the first user mode string performs those one or more designated tasks using the privileged execution mode. Applicants' method continues to permit the first user mode string to operate in the privileged execution mode after completion of the one or more designated tasks.

摘要： A sleep function capable of putting a fixed high-priority thread to sleep within a time-window is disclosed. After a sleep request has been made by a fixed high-priority thread via the sleep function, a determination is made whether or not the fixed high-priority thread is awoken before a requested sleep duration under the sleep request. If the fixed high-priority thread is awoken before the requested sleep duration, the number of tasks for the fixed high-priority thread to perform is increased in order to delay the start sleep time of the fixed high-priority thread from a point within a first time-window in which the sleep request was made to an end boundary of the first time-window.
