• Loop unwinding — Loop unwinding, also known as loop unrolling, is a loop transformation technique that attempts optimize a program s execution speed at the expense of its size.The goal of loop unwinding is to increase the programs speed by reducing (or… …   Wikipedia

• Loop unswitching — (размыкание цикла) состоит в вынесении условия за пределы цикла и дублирования тела цикла с помещением соответствующих вариантов в соответствующие ветви условия. Это позволяет улучшить производительность за счёт того, что современные процессоры… …   Википедия

• Loop optimization — In compiler theory, loop optimization plays an important role in improving cache performance, making effective use of parallel processing capabilities, and reducing overheads associated with executing loops. Most execution time of a scientific… …   Wikipedia

• Compiler optimization — is the process of tuning the output of a compiler to minimize or maximize some attributes of an executable computer program. The most common requirement is to minimize the time taken to execute a program; a less common one is to minimize the… …   Wikipedia

• Software pipelining — In computer science, software pipelining is a technique used to optimize loops, in a manner that parallels hardware pipelining. Software pipelining is a type of out of order execution, except that the reordering is done by a compiler (or in the… …   Wikipedia

• Algorithmic efficiency — In computer science, efficiency is used to describe properties of an algorithm relating to how much of various types of resources it consumes. Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or… …   Wikipedia
