http://jeffe.cs.illinois.edu/compgeom/code.html WebThe polyhedral model for loop parallelization has proved to be an effective tool for advanced optimization and automatic parallelization of programs in higher-level languages. Yet, to integrate such optimizations seamlessly into production compilers, they must be performed on the compiler's internal, low-level, intermediate representation (IR).

The polyhedral model (also called the polytope method) is a mathematical framework for programs that perform large numbers of operations -- too large to be explicitly enumerated -- thereby requiring a compact representation. Nested loop programs are the typical, but not the only example, and the most … See more Consider the following example written in C: The essential problem with this code is that each iteration of the inner loop on a[i][j] requires that the previous iteration's result, a[i][j - 1], be … See more The following C code implements a form of error-distribution dithering similar to Floyd–Steinberg dithering, but modified for pedagogical … See more • "The basic polytope method", tutorial by Martin Griebl containing diagrams of the pseudocode example above • "Code Generation in the Polytope Model" See more • Frameworks supporting the polyhedral model • Loop nest optimization • Loop optimization See more WebNov 13, 2024 · Hi, I am trying to plot the feasible set of a JuMP model as a 3D figure.

If neither Fourier-Motzkin nor block elimination is implemented or if the V-representation is already computed then :ProjectGenerators is chosen. Otherwise, Polyhedra lets the library decide. theraband made in germany
