Muitos historiadores e escritores modernos estão imbuídos do dogma marxista, segundo o qual o advento do socialismo é não só inevitável, como também extremamente desejável, e as forças traba- lhistas foram designadas para a histórica missão de destruir o sistema capitalista. Partindo dessa premissa, consideram natural que os par- tidos de “esquerda”, os eleitos, recorram à violência e ao crime para atingir seus objetivos.

Basic operating decisions include product positioning or pricing. Strategic business decisions involve priorities, goals and directions at the broadest level. In all cases, BI is most effective when it combines data derived from the market in which a company operates (external data) with data from company sources internal to the business such as financial and operations data (internal data). When combined, external and internal data can provide a more complete picture which, in effect, creates an "intelligence" that cannot be derived by any singular set of data.^[3] Amongst myriad uses, business intelligence tools empower organizations to gain insight into new markets, to assess demand and suitability of products and services for differentmarket segments and to gauge the impact of marketing efforts.^[4]

Abstract This paper shows that many applications exhibit execution- phase-specific sensitivity towards approximation of the in- ternal subcomputations. Therefore, approximation in certain phases can be more beneficial than others. Further, this paper presents OPPROX, a novel system for application’s execution- phase-aware approximation. For a user provided error bud- get and target input parameters, OPPROX identifies different program phases and searches for profitable approximation settings for each phase of the application execution. Our evaluation with five benchmarks and four existing transfor- mations show that our phase-aware optimization on average does 14% less work for a 5% error tolerance bound and 42% less work for a 20% tolerance bound

Approximate computing trades accuracy of computation for savings in execution time and/or energy by leveraging approx- imation opportunities across the computing stack, including programming languages[ 14 , 34 , 38 , 40 ], compilers[ 7 , 26 , 42 , 43 ], runtime systems[ 9 , 18 , 21 ], and hardware[ 17 , 19 , 32 , 41 ]. In addition to data-parallel and streaming applications[ 23 , 24 , 39 ] researchers proposed approximation techniques suit- able for iterative numerical computations, such as iterative solvers, large scale numerical models, and sparse matrix calculations[16, 46, 47]. Approximate computing techniques typically introduce inexactness and/or approximation by transforming compute- intensive kernels, which we call approximable blocks (ABs). Furthermore, many approximation techniques expose knobs to calibrate the approximation levels (ALs), which control the error or speedup. For instance, loop perforation [ 26 , 43 ] skips a fraction of a loop’s iterations, and exposes this fraction as a knob to control the accuracy/speedup tradeoff.

Outer-Loop Pattern. Many applications follow a compu- tation pattern in which the majority of computation is per- formed inside a main loop (we refer to it as the outer loop) encompassing all the ABs. Examples of outer loops include timestep loops in scientific simulations, convergence loops in iterative solvers, or enumerator loops for processing a series of information blocks (e.g., video frames).

For large applications with multiple ABs, the trade-off between speedup and error becomes complex. Often the optimum configuration of ALs in the various ABs are not obvious, especially if the approximation of internal ABs influences the number of iterations of the outer loop. Off-line exhaustive search can be possible only for a small number of approximate program configurations[ 43 ], and the majority of the previous approaches used various heuristic search strategies based on representative inputs[ 7 , 14 , 26 , 38 ], or dynamically tuned the ALs based on the observed errors from the approximated regions[ 7 , 25 , 38 , 44 ]. While many of these techniques identify and leverage properties of specific code patterns in ABs, they typically apply the same transformation for the entire execution and/or input. Such fixed optimization choices may lead to rigid transformed programs that miss fine-grained optimization opportunities

Phase-Aware Optimization. For many iterative computa- tions, the outer loop controls the precision of the final solution. Here, the iterations of the outer loop naturally segment the overall application execution into multiple phases. We define a phase as a segment of execution that has distinct speedup or error characteristics. For example, a numerical solver execu- tion can go through an initialization phase, a maturity phase, and a convergence phase. Our experimental results show that two different phases of the computation may generate different amounts of error for the same level of approximation. This exposes a new opportunity for optimization algorithms – they can select not just how much to approximate, but also in which phase to approximate. We find empirically that for some applications (such as LULESH[ 3 ]), approximating one phase may induce almost 8X less error than applying the same approximation in another phase of the executio

Our Solution Approach. We present OPPROX, a system for phase-aware optimization of approximate programs. OPPROX takes as inputs: a program with tunable approximable blocks and a user-provided accuracy specification, which consists of (1) a set of representative inputs that exercise the application’s desired functionality, (2) an accuracy metric that tells how to compute the difference between the results of the exact and the approximate execution, and (3) an error budget e b that specifies how much reduction in the accuracy metric in the final output the user is ready to tolerate
