Seismic imaging, used in energy exploration, is arguably the most compute and data intensive application in the private sector. The commonly used methods involve solving the wave equations numerically using finite difference formulations. Writing optimised code for these applications involves multiple man-years of effort that needs to be repeated every time a new development needs to be factored in – for every target platform. <br><br>DeVito is a new tool for performing optimised Finite Difference (FD) computation from high-level symbolic problem definitions. The application developer needs to provide a differential equation in symbolic form. DeVito performs automated code generation and Just-In-time (JIT) compilation based on this symbolic equation to create and execute highly optimised Finite Difference kernels on multiple computer platforms. DeVito has been designed to be used as part of complex workflows involving data flows across multiple applications over different nodes of a cluster.
