However, the main challenge of this approach is that the code implementing the desired concept often involves multiple classes, and may Krzysztof Czarnecki Electrical and Computer Engineering Department, University of Waterloo, Canada czarnecki@acm.org be scattered across and tangled with code implementing other concepts.

the purpose of this step is to .nd and mark other interactions that might be relevant to the implementation of the desired concept and happen either before or after invoking it.


All of these techniques attempt to minimize the power con sumption of a single device, managed individually by a user.

in contrast to the approach presented in this paper, virtualization and consolidation in clouds focus on highly centralized and controllable high-performance data centre environments.

the analysis is performed as the application runs, and is done by observing how values are used in the computation as opposed to reasoning about how they must have been used in the computation.


Nevertheless, current approaches are only focused in persistence, giving few or no support for (meta)model versioning, which is a necessary feature to allow incremental development and evolution of (meta)models.

the latter is very similar to a delta-based version control scheme since the stored metadata would show the changes between versions.


The aim of the algorithm is to allow multiple nodes in the virtual ring to enter into the Group Messaging Request (GMR) mode simultaneously or concurrently.

In consequence, the availability analyses ignores that the state of service providers and access points can change in the near future.

let us assume that, from previous experiences, engineers know that observing a continuous unavailability of a provider during the last week would likely mean that this provider disappeared.

Therefore, the case argument should be evaluated to head normal form i.e., a variable or an expression with a constructor at the outermost position.

similarly to the heap, we use G[r .e] either as a condition on a graph G or as a modi.cation of G. A brief explanation for each rule of the semantics follows: (varcons and varexp) Since these rules are used to perform a variable lookup in the heap, a new variable pointer for x is added to the graph if it does not yet contain such a pointer to denote that the value of x is needed in the computation.

this would incur a heavy runtime overhead because it would require book-keeping every time the branch instruction is executed.


For example, even something as simple as managing the access to some shared resource, say a database, might require the user code to register its intent to use the resource and to release it afterwards.

the use of runtime aspects means that it becomes possible not only to enforce some architectural constraints, but also to satisfy them directly and free the user of that task.


Since you are proceeding in a Step by Step fashion and learning about the change initiative and the organization as you go, this will provide a learning opportunity for everyone concerned.

The second and third columns present the average bytes written and read per subjob run, and the fourth column shows the ratio of I/O to execution time.

our approach prevents all dialog boxes from popping up, and the error string that would have been displayed in the dialog box is stored and sent back to the user.


But a pattern captures a part of a system that has a large number of inner connections and only a small number of connections to its environment, making its configuration nearly independent (Simon, 1969).

they have not been docum ented in the pattern format yet.


An alternative approach was that of Knuth [12], who, rather than examining faults, directly analyzed the errors (in the IEEE sense of the word) found or reported in ten years of development of his well-known typesetting software, TEX into nine categories (Knuth also recorded seven categories of enhancements ).

the proportions for Class .eld related (CF) .xes were somewhat outside their ranges, and large di.erences were found in the Method call related (MC), Assignment related (AS) and Method Declaration related (MD) groups, with 12.4%, 0.9% and 34.3% respectively in our results, with 21.9-22.9%,6.3-14.2% and 8.1-22.7% respectively in theirs.

Unlike in the first and the secondgeneration solutions, the third-generation architectures have two kinds of peers: peers and super-peers.

nowadays a developer must often decide between programming languages based on the requirements of a particular application, since most of their mobile versions of APIs have artificially hindered functionalities.


The TAU overhead for each method is different and is influenced by the time spent looking up the mapping table, string operations that depend upon the length of a method name, load on the system, and other plat- form specific parameters.

Neither of these features of the monad is activated by this example though.

large sorters that are not themselves sorting networks (with typical examples being radix sort and quicksort) often call small sorting networks when they need to sort small arrays during their execution.


Such reordering happens because the compiler optimistically assumes the operations never alias.

for mayalias operations, the compiler optimistically assumes they never alias with each other, so as to speculatively schedule them to run out of order; the compiler sets up the hardware to detect any aliases, if any, when the optimized code runs.


Hence, without prior knowledge of at least some nonlocal aspects of the network topology, the Byzantine general remains undetected.

Once the developer was warned by the tool about such inconsistencies, he/she is in charge of solving the detected problem (for instance by explicitly declaring the inconsistent methods as deviating cases to be included in the already existent alternative view).

the model-based pointcut approach addresses the fragile pointcut problem by replacing the intimate dependency of pointcut definitions on the base program by a more stable dependency on a conceptual model of the program.

to summarize, we make three main contributions: We observe the overload continuum: memory overloads encountered in a data center are, and will likely continue to include both transient and sustained bursts, although an overwhelming majority will be transient.


When passed to unstream, this results in two loops, one executed after the other, that write elements one by one into a newly allocated vector.

we chose Leap to contain four values so loops are unrolled four times since on x86-64 processors this tends not to put too much register pressure on the register allocator.


The shortcoming of the work is that the tool does not follow any industrial guideline while generating a Simulink model.

modularization of this sort is fairly well accepted and understood within the scienti.c computing community (though not necessarily easily implemented or universally used in such contexts), and I believe many will be satis.ed to develop coupled simulations without the bene.ts of CBSE unless they perceive a greater level of bene.t.


Unfortunately, time would pass between these meetings and the actual implementation of the API.

in another occasion, a client developer followed his dependency in order to switch teams: he had a dependency on the server team, who actually had a dependency in the infra-structure team, who depended on an external team to provide the component.
