A mechanism is provided for fostering the adoption of grid computing by bridging the thread-oriented paradigm (used in single and multi-processor computers) and the job-oriented paradigm (used in grid computing). This mechanism allows an application developer to write an application in the same manner as if he were writing a thread-oriented program (in terms of creating and joining threads). However, when the application is executed on a client computer and the mechanism is invoked, the mechanism interacts with a resource management interface to cause a distributed resource manager to create, distribute, and manage the execution of jobs on the resource computers of a grid. Thus, rather than actually spawning threads on the client computer, the mechanism causes jobs to be spawned and executed on the grid. By doing this, the mechanism allows the application to take advantage of grid computing without requiring the application to be grid-aware.

A method for estimating energy usage of a program code executed by a very long instruction word (VLIW) processor. The program code includes multiple instructions, which are organized as groups referred to as execution sets. The instructions of an execution set are executed simultaneously. A no operation (NOP) energy and incremental instruction energy for each execution set of the program code are determined to compute a base energy of each execution set. An inter-execution set energy of each execution set is then computed. The estimated energy usage of each execution set is determined by adding the corresponding inter-execution set energies to the base energies. A stall energy consumed on account of executing the program code is then computed. Finally, the estimated energy usage of the program code is determined by adding the stall energy to the determined energies of all the execution sets.

A signal conditioning circuit dynamically adjusts a compression ratio, so as to compress a signal and avoid limiting to the extent possible, thereby avoiding distorting the signal by clipping. An input signal is applied to the input of a programmed gain amplifier (PGA) or other amplifier whose gain can be controlled by a gain control signal.
