In computing, an array of structures (AoS), structure of arrays (SoA) or array of structures of arrays (AoSoA) are contrasting ways to arrange a sequence of records in memory, with regard to interleaving, and are of interest in SIMD and SIMT programming.

Mar 26, 2019 · This chapter examines a useful user code transformation: moving from data organized in an Array of Structures (AoS) to an organization of Stucture of Arrays (SoA). This transformation allows the compiler to access data more efficiently on the processor.

Aug 9, 2021 · Learn about the pros and cons of distinct memory layouts, as well as memory pools for asynchronous memory allocation to enable zero-copy functionality.

Dec 18, 2018 · Here is how to use the SoA to optimize caching and performance when accessing one member of a structure in a collection.

We present diferent techniques for in-lining (embedding) inner arrays into an AOS or SOA layout, as well as the design and implementation of an embedded C++/CUDA DSL that lets programmers write such layouts in a notation close to standard C++.

To read or write any cell, you need to perform one, two, or three actions: Read the contents of a row in a row buffer, which temporarily discharges the capacitors. Read or write a specific cell in this buffer.

Memory access patterns are critical for performance, especially on parallel architectures such as GPUs. Because of this, the choice between an array-of-structures (AoS) data layout and a structure-of-arrays (SoA) layout has a large impact on overall program performance.

Clas-sical data layout transformations include grouping together data elds that have similar access patterns, or transforming Array-of-Structures (AoS) to Structure-of-Arrays (SoA). This paper presents an optimization infrastructure to automatically de-termine an improved data layout for OpenCL programs written in AoS layout.

Feb 18, 2025 · The SoA representation allows us to do optimizations like vectorization that can help us decrease the runtime of programs. In addition, if coupled with in place updates, the SoA representation will allow us to skip unused fields which can further decrease the runtime.

The SoA layout is not a good option because the color channels of a pixel are stored far apart in the memory space. We describe how to construct AoS and SoA fields with our ti.root.X statements.
