摘要： A computer implemented method, apparatus, and computer usable program code for establishing a priority level for data in a cache. A determination is made whether data is designated for slower aging within the cache during execution of instructions for an application. The priority level for the data in the cache is set in response to a determination that the data is designated for slower aging. The priority level indicates that the data is aged slower than other data without the priority level.

摘要： Standalone software performance optimizer systems for hybrid systems include a hybrid system having a plurality of processors, memory operably connected to the processors, an operating system including a dispatcher loaded into the memory, a multithreaded application read into the memory, and a static performance analysis program loaded into the memory; wherein the static performance analysis program instructs at least one processor to perform static performance analysis on each of the threads, the static performance analysis program instructs at least one processor to assign each thread to a CPU class based on the static performance analysis, and the static performance analysis program instructs at least one processor to store each thread's CPU class. An embodiment of the invention may also include the dispatcher optimally mapping threads to processors using thread CPU classes and remapping threads to processors when a runtime performance analysis classifies a thread differently from the static performance analysis.

摘要： A symmetric multi-processor SMP system includes an SMP processor and operating system OS software that performs automatic SMP lock tracing analysis on an executing application program. System administrators, users or other entities initiate an automatic SMP lock tracing analysis. A particular thread of the executing application program requests and obtains a lock for a memory address pointer. A subsequent thread requests the same memory address pointer lock prior to the particular thread release of that lock. The subsequent thread begins to spin waiting for the release of that address pointer lock. When the subsequent thread reaches a predetermined maximum amount of wait time, MAXSPIN, a lock testing tool in the kernel of the OS detects the MAXSPIN condition. The OS performs a test to determine if the subsequent thread and address pointer lock meet the list of criteria set during initiation of the automatic lock trace method. The OS initiates an SMP lock trace capture automatically if all criteria or the arguments of the lock trace method are met. System administrators, software programmers, users or other entities interpret the results of the SMP lock tracing method that the OS stores in a trace table to determine performance improvements for the executing application program.

摘要： A method, computer program product, and system are provided for prefetching data into a cache memory. As a program is executed an object identifier is obtained of a first object of the program. A lookup operation is performed on a data structure to determine if the object identifier is present in the data structure. Responsive to the object identifier being present in the data structure, a referenced object identifier is retrieved that is referenced by the object identifier. Then, the data associated with the referenced object identifier is prefetched from main memory into the cache memory.

摘要： A method utilizes cluster-awareness to effectively support a live partition mobility (LPM) event and provide recovery from node failure within a Virtual Input/Output (I/O) Server (VIOS) cluster. An LPM utility creates a monitoring thread on a first VIOS on initiation of a corresponding LPM event. The monitoring thread tracks a status of an LPM and records status information in the mobility table of a database. The LPM utility creates other monitoring threads on other VIOSes running on the (same) source server. If the first VIOS VIOS sustains one of multiple failures, the LPM utility provides notification to other functioning nodes/VIOSes. The LPM utility enables a functioning monitoring thread to update the LPM status. In particular, a last monitoring thread may perform cleanup/update operations within the database based on an indication that there are nodes on the first server that are in failed state.
