loop fusion การใช้

• Loop fusion does not always improve run-time speed.
• This includes loop interchange, loop fusion, loop unrolling, loop distribution, data prefetch, and more.
• ;Loop fusion or loop combining or loop ramming or loop jamming : Another technique which attempts to reduce loop overhead.
• This book detailed the construction of an APL C, which performed certain optimizations such as loop fusion specific to the needs of an array language.
• The "'Tensor Contraction Engine "'( TCE ) transforms tensor summation expressions to low level code ( C / Fortran ) for specific hardware being mindful of memory availability, communication costs, loop fusion and ordering, etc . . . . It is used primarily in computational chemistry.
• Instance-wise analysis and transformation allows the polyhedral model to unify additional transformations ( such as index set splitting, loop peeling, tiling, loop fusion or fission, and transformation of imperfectly nested loops ) with those already unified by the unimodular framework ( such as loop interchange, skewing, and reversal of perfectly nested loops ).
