💽 LAT - Lara Autotuning Tool

  • Developed at SPeCS at FEUP.
  • LAT is a tool for code autotuning, built using LARA (a Javascript based language that supports source code transformations) and applied using the Clava tool.
  • LAT mimics Intel Software Autotuning Tool (ISAT) behaviour for testing multiple instances of the same code. However, it is build entirely on LARA. Because of this it is platform agnostic and can be more flexible and easier to expand, both in functionalities and languages (not only C and C++).
Tools: cmake | clava | lara
