M.S. Paper Title: EIN notation in the Diderot compiler

Abstract:
Research scientists and medical professionals use imaging technology
to measure a wide variety of biological and physical objects. The
increasing sophistication of imaging technology creates demand for
equally sophisticated computational techniques to analyze and
visualize the image data. Diderot is a domain-specific programming
language for scientific visualization. Diderot supports a high-level
model of computation based on continuous tensor fields. These tensor
fields are reconstructed from discrete image data using separable
convolution kernels or from applying differentiation on fields.
Diderot’s surface language is similar to its mathematical counterpart.
For example, the tensor and field operations ∇, · are supported
in Diderot. The current direct-style Diderot compiler is limited by
the type of operations it supports. To address these limitations, we
introduce the design and implementation of EIN notation in the Diderot
compiler. EIN notation is inspired by Einstein index notation with
some extensions to represent the algorithms used in image analysis.
The notation allows a concise and expressive way to represent a
diverse set of tensor and field operations. We extend the operations
supported in the surface language while providing the basis for more
operations. The mathematically well-founded compiler can do
index-based optimizations supported by tensor calculus to find
algebraic identities and simplification and do domain-specific
optimizations.

Charisee's advisor is Prof. John Reppy
