A program pro le attributes run-time costs to portions of a program's execution. Most pro ling systems su er from two major de ciencies: rst, they only apportion simple metrics, such as execution frequency or elapsed time to static, syntactic units, such as procedures or statements; second

One of the major challenges of post-PC computing is the need to reduce energy consumption, thereby extending the lifetime of the batteries that p ower these mobile devices. Memory is a particularly important tar get for e orts to improve energy e ciency. Memory technolo gy is becoming available

The very high level and constant growth in salaries for corporate executives has been a trend causing debate for over a decade now. It has given rise to a range of argu-ments for and against high salary levels. The single most prevalent argument for high executive salaries has been the argument

) and ªhidden ac-tionº (leading to moral hazard). Our theoretical analysis suggests four em-pirical predictions. 1. Venture capitalists operate in environments where their relative ef®ciency in selecting and monitoring investments gives them a comparative advantage over other investors. This suggests strong

of the quality of results and execution e ciency, is a feature that enables the integration of designer knowledge about the system structure into an otherwise fully automatic clustering process. We use a case study to show how our new features simpli ed the task of extracting the subsystem structure ofamedium

Temporal plans permit significant flexibility in specifying the occurrence time of events. Plan execution can make good use of that flexibility. However, the advantage of execution flexibility is counterbalanced by the cost during execution of propagating the time of occurrence of events

While ne-grained concurrent languages can naturally capture concurrency in many irregular and dynamic problems, their exibility has generally resulted in poor execution e ciency. In such languages the computation consists of many small threads which are created dynamically and synchronized

-level, uniform abstraction over different data representations and execution strategies. To enable parallel operations to run effi-ciently, FlumeJava defers their evaluation, instead internally con-structing an execution plan dataflow graph. When the final results of the parallel operations are eventually needed

comprehensive BEC classifi cation for the former Nelson Forest Region (NFR) was completed in 1992. This was followed by publication of a fi eld guide characterizing the site series for 18 subzones and variants of the NFR. A preliminary assessment indicates there are major defi ciencies in the BEC classifi

-memory execution mode is supported which establishes customized EEs in compute nodes without a#ecting the OS/data stored in the permanent storage. Experimental results demonstrate the e#ciency of SLIM in a network involving 272 machines.
