Abstract: Methods, apparatus and systems for memory access obscuration are provided. A first embodiment provides memory access obscuration in conjunction with deadlock avoidance. Such embodiment utilizes processor features including an instruction to enable monitoring of specified cache lines and an instruction that sets a status bit responsive to any foreign access (e.g., write or eviction due to a read) to the specified lines. A second embodiment provides memory access obscuration in conjunction with deadlock detection. Such embodiment utilizes the monitoring feature, as well as handler registration. A user-level handler may be asynchronously invoked responsive to a foreign write to any of the specified lines. Invocation of the handler more frequently than expected indicates that a deadlock may have been encountered. In such case, a deadlock policy may be enforced. Other embodiments are also described and claimed.

Abstract: A power level monitor and performance tracking tool are provided for correlating system performance with processor management events. When power management requires a change to the state of a microprocessor, software will be notified. Multiple layers of software may be notified, including a firmware level, an operating system, as well as applications. The performance tracking tool tracks the times of the power management events as well as their impact to the microprocessor performance. The performance tracking tool may then display or record the state changes to processor performance. These changes may be correlated against other system events to aid in determining system performance problems with respect to power management.

Abstract: Techniques are described for optimizing memory management in a processor system. The techniques may be implemented on processors that include on-chip performance monitoring and on systems where an external performance monitor is coupled to a processor. Processors that include a Performance Monitoring Unit (PMU) are examples. The PMU may store data on read and write cache misses, as well as data on translation lookaside buffer (TLB) misses. The data from the PMU is used to determine if any memory regions within a memory heap are delinquent memory regions, i.e., regions exhibiting high numbers of memory problems or stalls. If delinquent memory regions are found, the memory manager, such as a garbage collection routine, can efficiently optimize memory performance as well as the mutators performance by improving the layout of objects in the heap. In this way, memory management routines may be focused based on dynamic and real-time memory performance data.

Abstract translation: 描述了用于优化处理器系统中的存储器管理的技术。 这些技术可以在包括片上性能监视的处理器以及外部性能监视器耦合到处理器的系统上实现。 包括性能监控单元（PMU）的处理器就是例子。 PMU可以将数据存储在读取和写入高速缓存未命中，以及翻译后备缓冲区（TLB）未命中的数据。 来自PMU的数据用于确定存储器堆中的任何存储器区域是否是过期存储器区域，即表现出大量存储器问题或失速的区域。 如果发现存在不正当的内存区域，诸如垃圾收集例程的存储器管理器可以通过改进堆中对象的布局来有效地优化存储器性能以及突变器的性能。 以这种方式，可以基于动态和实时存储器性能数据来集中存储器管理例程。

Abstract: An estimate of the throughput of a multi-threaded processor based on measured miss rates of a cache memory associated with the processor is adjusted to account for cache miss processing delays due to memory bus access contention. In particular, the throughput calculated from the cache memory miss rates is initially calculated assuming that a memory bus between the cache memory and main memory has infinite bandwidth, this throughput estimate is used to estimate a request cycle time between memory access attempts for a typical thread. The request cycle time, in turn, is used to determine a memory bus access delay that is then used to adjust the initial processor throughput estimate. The adjusted estimate can be used for thread scheduling in a multiprocessor system.

Abstract: A load balancer detects a server failure, and sends a failure notification message to the remaining servers. In response, one or more of the remaining servers may autonomically adjust their configuration parameters, thereby allowing the remaining servers to better handle the increased load caused by the server failure. One or more of the servers may also include a performance measurement mechanism that measures performance before and after an autonomic adjustment of the configuration parameters to determine whether and how much the autonomic adjustments improved the system performance. In this manner server computer systems may autonomically compensate for the failure of another server computer system that was sharing the workload.
