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
Performance measurement — with a process is the complement to process execution. Based on measured performance, the feedback control loop may be closed. The metrics to assess performance is set according to a determined econometric model. The expected best result is… … Wikipedia
Performance tuning — is the improvement of system performance. This is typically a computer application, but the same methods can be applied to economic markets, bureaucracies or other complex systems. The motivation for such activity is called a performance problem … Wikipedia
Loop fusion — Loop fusion, also called loop jamming, is a compiler optimization, a loop transformation, which replaces multiple loops with a single one. Example in C int i, a [100] , b [100] ; for (i = 0; i < 100; i++) { a [i] = 1; } for (i = 0; i < 100; i++)… … Wikipedia
Loop nest optimization — (LNO) is a special case of loop transformation, dealing with nested loops, that allows large reductions in the cache bandwidth necessary for some common algorithms.Example: Matrix multiplyMany large mathematical operations on computers end up… … Wikipedia
Loop tiling — Loop tiling, also known as loop blocking, strip mine and interchange, unroll and jam, or supernode partitioning, is a loop optimization used by compilers to make the execution of certain types of loops more efficient.Loop tiling partitions a loop … Wikipedia
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
Loop interchange — In compiler theory, loop interchange is the process of exchanging the order of two iteration variables. For example, in the code fragment: for i from 0 to 10 for j from 0 to 20 a [i,j] = i + jloop interchange would result in: for j from 0 to 20… … Wikipedia
Loop antenna — A shortwave loop antenna A loop antenna is a radio antenna consisting of a loop (or loops) of wire, tubing, or other electrical conductor with its ends connected to a balanced transmission line. Within this physical description there are two very … Wikipedia
Loop-switch sequence — A loop switch sequence is a specific derivative of the spaghetti code programming antipattern where a clear set of steps is implemented as a byzantine switch within a loop. Also known as The FOR CASE paradigm… … Wikipedia
