Web– Parameterized tiled loops for free, PLDI 2007 – HiTLOG - A Tiled Loop Generator that is part of AlphaZ Overview of decoupled approach – find polyhedron that may contain any loop origins – generate code that traverses that polyhedron – post process the code to start a tile origins and step by tile size ... WebOur code generation efficiency is comparable to all existing code generation techniques including those for fixed tile sizes, and the resulting code is as efficient as, if not more …
Parametric Multi-Level Tiling of Imperfectly Nested Loops
WebAn approach is presented permitting us to build free scheduling for statement instances of affine loops. Under the free schedule, loop statement instances are executed as soon as their operands are available. This allows us to extract maximal fine-... WebThus the technique provides parameterized tiled loops for free! Our “one-size-fits-all” solution, which is available as open source software can be adapted for use in production … toughest phone 2022
Parameterized Tiling - Colorado State University
WebTiled loops with parameterized tile sizes (not compile time constants) enable runtime optimizations used in iterative compilation and automatic tuning. Previous parametric multi-level tiling approaches have been restricted to perfectly nested loops, where all statements are contained inside the innermost loop of a loop nest. ... Web–Parameterized tiled loops for free, PLDI 2007 –HiTLOG-A Tiled Loop Generator that is part of AlphaZ do ii = 1,6, by 2 do jj = 1, 5, by 2 do i = ii, ii+2-1 do j = jj, min(jj+2-1,5) A(i,j) = ... CS 553 Tiling, ISCC Code Gen, and Fourier Motzkin 5 Specifying Tiling as a Schedule to a Code Generator Rectangular tiling –tile size vector –tile offset, WebWhen an iteration space is rectangular, generating (even parameterized) tiled loops and separating full tiles are trivial problem. Changing strides (and possibly each loop bound individually) are sufficient. Parameterized tiled loops—where tile sizes are run-time parameters and therefore can be adjusted between runs and even during a sin- toughest phone in the world
