The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read/write accesses (I/Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I/O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I/O streams is used to apply controls to guarantee quality of service to all I/O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I/O stream is created that will always be applied to that I/O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I/O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.

The present invention relates to a method for a random access process in a mobile communication system. According to the exemplary embodiments, in the case where a mobile terminal requests a random access to a network, when the network is not able to promptly allocate a resource for the random access to the mobile terminal due to an insufficient resource, the mobile terminal is maintained in a standby state without repeatedly requesting the random access to the network. Accordingly, it is possible to reduce the uplink signal interference caused by the repeated random access request, reduce the possibility of communication contention between the mobile terminals for the access to the mobile communication system, and reduce the power consumption of the mobile terminal.

Techniques used to enhance the execution of long-running or complex software application instances and jobs on computing systems are disclosed herein. In one embodiment, a real time, self-predicting job resource monitor is employed to predict inadequate system resources on the computing system and failure of a job execution on the computing system. This monitor may not only determine if inadequate resources exist prior to execution of the job, but may also detect in real time if inadequate resources will be encountered during the execution of the job for cases where resource availability has unexpectedly decreased. If a resource deficiency is predicted on the executing computer system, the system may pause the job and automatically take corrective action or alert a user. The job may resume after the resource deficiency is met. Additional embodiments also integrate this resource monitoring capability with the adaptive selection of a computer system or application execution environment based on resource capability predictions and benchmarks.

When large numbers of children play in a playground, part of the power of their play could be usefully harnessed resulting in large energy storage. This stored energy can then be converted for basic, low-power, applications in the school such as lighting, communication, or operating fans. Energy can be produced through the use of pneumatic (i.e., compressed air) systems such as cylinders, motors, valves, and regulators for the conversion of human power of children's play in school playgrounds and other public places. The energy of the compressed air can then be converted to electricity for purposes such as lighting and communication. This provides a low-cost, low-resource means of generation of electricity, especially for use in developing countries.

Embodiments of the present invention provide an architecture for securely and efficiently executing byte code generated from a general programming language. In particular, a computer system is divided into a hierarchy comprising multiple types of virtual machines. A thin layer of software, known as a virtual machine monitor, virtualizes the hardware of the computer system and emulates the hardware of the computer system to form a first type of virtual machine. This first type of virtual machine implements a virtual operating domain that allows running its own operating system. Within a virtual operating domain, a byte code interpreter may further implement a second type of virtual machine that executes byte code generated from a program written in a general purpose programming language. The byte code interpreter is incorporated into the operating system running in the virtual operating domain. The byte code interpreter implementing the virtual machine that executes byte code may be divided into a kernel component and one or more user level components. The kernel component of the virtual machine is integrated into the operating system kernel. The user level component provides support for execution of an applet and couples the applet to the operating system. In addition, an operating system running in a virtual operating domain may be configured as a special purpose operating system that is optimized for the functions of a particular byte code interpreter.
