Принадлежит: International Business Machines Corp

Occurrences of a particular event in an electronic device are counted by incrementing an event counter each time a variable number of the particular events have occurred, and automatically increasing that variable number as the total count increases. The variable number (prescale value) can increase geometrically according to a programmable counter base each time the count mantissa overflows. The event counter thereby provides hardware-implemented automatic prescaling while significantly reducing the number of interface bits required to support very large count ranges, and retaining high accuracy at very large event counts.

A kernel trace system is described that acts as a kernel driver to insert traces into an open system kernel using existing kernel probe application-programming interfaces (APIs) and copies these events to an existing logging module for transfer to user space. The new module aggregates kernel traces to a performance logging module. A performance logging module can be extended with the kernel trace system herein to include new events in an open kernel not originally included in the implementation of the performance logging module. In this way, the kernel trace system can cause events to be logged that were not logged in the kernel as provided by the operating system vendor, and can do so without requiring that a new version of the operating system be built. The probes can be inserted dynamically at run time on an existing kernel to extract additional trace information.

Hardware profiling mechanism to enable page level automatic binary translation

Принадлежит: Intel Corp

A hardware profiling mechanism implemented by performance monitoring hardware enables page level automatic binary translation. The hardware during runtime identifies a code page in memory containing potentially optimizable instructions. The hardware requests allocation of a new page in memory associated with the code page, where the new page contains a collection of counters and each of the counters corresponds to one of the instructions in the code page. When the hardware detects a branch instruction having a branch target within the code page, it increments one of the counters that has the same position in the new page as the branch target in the code page. The execution of the code page is repeated and the counters are incremented when branch targets fall within the code page. The hardware then provides the counter values in the new page to a binary translator for binary translation.

A failover guaranty estimator module performs a proof by contradiction method showing that a cluster failover guaranty can be met for the cluster. For potential failures for which failover is guaranteed, the method assumes a particular host set of one or more hosts fails, leaving one or more working hosts. The method performs a per-failure host set method for the failure host set. The per-failure host set method determines an amount of memory usage within each working host of the assumed working host set that would guaranty that a largest of the virtual machines in the failure host set would be orphaned. The per-failure host set method determines if the virtual machines in the failure set, other than the largest virtual machine in that set, would force the determined amount of memory usage within working hosts, resulting in, the failover guaranty not being met.

A processor performance profiler is enabled to for identify specific instructions causing performance issues within a program being executed by a microprocessor through random sampling to find the worst-case offenders of a particular event type such as a cache miss or a branch mis-prediction. Tracking all instructions causing a particular event generates large data logs, creates performance penalties, and makes code analysis more difficult. However, by identifying and tracking the worst offenders within a random sample of events without having to hash all events results in smaller memory requirements for the performance profiler, lower performance impact while profiling, and decreased complexity to analyze the program to identify major performance issues, which, in turn, enables better optimization of the program in shorter developer time.

In an embodiment of the invention an application provider may include “tracing elements” in a target software application. While working with the application the trace elements are detected and provide a “baseline trace” indicating proper application execution. The provider then supplies the application, which still includes the trace elements, and the baseline trace to a user. The user operates the application to produce a “real-time trace” based on the application still having trace elements that produce trace events. A comparator then compares the baseline and real-time traces. If the traces are within a pre-determined range of each other the user has a level of assurance the software is operating correctly. If the level of assurance is low, an embodiment may trigger a hardware interrupt or similar event to prevent further execution of software. Other embodiments are described herein.
