A method and system for determining potential deadlock conditions in a target multi-threaded software application. The target application is first run in a virtual machine and the events within the application are recorded. The recorded events are replayed and analyzed to identify potential lock acquisition conflicts occurring between threads of the application. The potential lock acquisition conflicts are identified by analyzing the order in which resource locks are obtained and pairs of resources that have respective locks obtained in different orders are analyzed. These analyzed pairs are used to define a different order of events in the target application that, when the target application is re-run with the second order of events, may trigger a deadlock condition. The target application is then re-run with the different order of events in an attempt to trigger and then identify potential deadlock situations.

Номер: US20120066616A1
Автор: Alex J. Glover, Daniel James Plaster, Herman H. Ng, Shawn M. Woods
Принадлежит: Individual

Various embodiments provide message queue management techniques designed to reduce the likelihood of multi-component applications becoming nonresponsive and enable recovery options for individual components if they do become nonresponsive. In at least some embodiments, a message queue manager detects when a component of an application interface becomes nonresponsive and detaches the component from a shared message queue. The shared message queue can continue to process messages for other responsive components while messaging for the nonresponsive component is managed via a separate queue. The message queue manager can also notify a user regarding the nonresponsive component and provide the user with options to facilitate recovery of the nonresponsive component. Further, in at least some embodiments, the message queue manager can monitor a detached component and reattach the detached component when it becomes responsive again.

When plural virtual servers are distributed to plural physical servers, efficient distribution is performed in terms of the processing capacity of the physical servers and their power consumption. Firstly a second load of each virtual server in future is predicted based on a first load in a prescribed time period up to the present of each of the plural virtual servers. Next, the schedule is determined to distribute the plural virtual servers to the plural physical servers based on the second load of each virtual server so that a total of the second loads of one or a plurality of the virtual servers distributed to a physical server is within a prescribed range of proportion with respect to processing capacity of the physical server. Furthermore, the distribution is instructed (execution of redistribution) in accordance with the schedule.

A processor includes an initiating hardware thread, which initiates a first assist hardware thread to execute a first code segment. Next, the initiating hardware thread sets an assist thread executing indicator in response to initiating the first assist hardware thread. The set assist thread executing indicator indicates whether assist hardware threads are executing. A second assist hardware thread initiates and begins executing a second code segment. In turn, the initiating hardware thread detects a change in the assist thread executing indicator, which signifies that both the first assist hardware thread and the second assist hardware thread terminated. As such, the initiating hardware thread evaluates assist hardware thread results in response to both of the assist hardware threads terminating.

A storage device including a migration source logical volume of an application copies data stored in the logical volume into a migration destination logical volume of the application. After the copy process is started, the storage device stores data written into the migration source logical volume as differential data without storing the data into the migration source logical volume. When the copy process is completed for the data stored in the migration source logical volume, a management computer starts copying of the differential data, and in a time interval after the copying of the data stored in the migration source logical volume is completed but before the copying of the differential data is completed, a computer being a migration destination of the application is turned ON, thereby reducing power consumption at the time of application migration.

Systems and methods are disclosed herein to automatically replicate virtual machine image (VM) files on secondary VM computing devices, from a primary VM computing device. The secondary VM computing devices are automatically selected by constantly reviewing the operating parameter values (e.g., cost of resources, power consumption, etc.) of a number of secondary VM computing devices available of storing VM image replicas. The replica of the primary VM image is stored in the secondary VM computing devices in geographically disparate cloud locations. The primary VM image is automatically broken into constituent data blocks stored in an active index, which is compared against a stale index of data blocks. When an update is detected in the primary VM image, the comparison of indices will indicate that there is new data. Only the new data is used to update the secondary VM images, thereby reducing network traffic and latency issues.

Table-driven soaker tool for information handling systems

Номер: US20120124350A1
Автор: Meik Neubauer
Принадлежит: International Business Machines Corp

A soaker tool for an information handling system (IHS) exercises the IHS to provide a predetermined amount of utilization that a user may specify. The soaker tool schedules wait times following respective utilization times in alternating fashion to achieve a desired utilization value for a predetermined time period. The soaker tool monitors for a dispatch interrupt during the utilization times. Should a dispatch interrupt occur during a utilization time, the soaker tool accounts for the dispatch interrupt by determining a remainder utilization time to maintain utilization accuracy. The soaker tool may employ a parameter table that specifies utilization times, wait times, loop counts and adjustment cycles indexed to the respective utilization values that a user may select. The soaker tool may employ adjustment cycles to compensate for cumulative timing errors that may occur when running the tool for extended time periods.

Embodiments relate to systems and methods for brokering optimized resource supply costs in a host cloud-based network using predictive workloads. In aspects, a set of usage histories can store patterns for users in a host cloud-based network recording the consumption of processor, memory, storage, operating system, application, or other resources subscribed to by the user. The operator of the cloud management system hosting the workloads of one or more users can track the aggregate user histories reflecting those workloads, and analyze them in terms of different time periods over which demands for resources may intensity or relax. The cloud management system can examine those workload patterns, and generate a set of predictively re-assigned workloads to be supported by different sets of resource servers during offpeak and/or other periods. The workload realignment to different resource servers can permit the operator of the cloud management system and/or other cloud provider to realize cost savings or other benefits by procuring resources on a predictive basis.

A technique for reducing reader overhead when referencing a shared data element while facilitating realtime-safe detection of a grace period for deferring destruction of the shared data element. The grace period is determined by a condition in which all readers that are capable of referencing the shared data element have reached a quiescent state subsequent to a request for a quiescent state. Common case local quiescent state tracking may be performed using only local per-reader state information for all readers that have not blocked while in a read-side critical section in which the data element is referenced. Uncommon case non-local quiescent state tracking may be performed using non-local multi-reader state information for all readers that have blocked while in their read-side critical section. The common case local quiescent state tracking requires less processing overhead than the uncommon case non-local quiescent state tracking.
