Skip Statement rules of the structural operational semantics of a language, ensuring that the equivalence is a congruence. Moreover, for several formats it is determined what is the coarsest congruence with respect to all operators in this format that is finer than partial or completed trace equivalence. « Operational semantics » Patrick Cousot Jerome C. Hunsaker Visiting Professor Massachusetts Institute of Technology Department of Aeronautics and Astronautics Operational Semantics. Pages 13-35.

Denotational semantics involves modeling programs as static mathematical objects, namely as set-theoretic functions with speciﬁc properties. We, however, will focus on a form of semantics called operational semantics. An operational semantics is a mathematical model 1.2 Operational Semantics The idea behind Operational Semantics is to express the meaning of a program starting from a certain state by looking at its end result, i.e. the state in which the memory is after execution This book provides a self-contained introduction to structural operational semantics, featuring semantic definitions using big-step and small-step semantics of many standard programming language constructs, including control structures, structured declarations and objects, parameter mechanisms and procedural abstraction, concurrency, nondeterminism and the features of functional programming OPERATIONAL SEMANTICS The style of operational semantics we shall study is that developed by Plotkin and Kahn (who called it natural semantics). The language is defined by a set of inference rule.

Labelled Operational semantics and attribute grammars are examples of formalisms that can be used for generating compilers.

Mathematical description of the meaning of programs written in that language •What a program computes, and what it does Operational semantics: define how programs execute •Often on an abstract machine (mathematical model of computer) •Analogous to interpretation CSE 6341 1 Operational Semantics Winskel, Ch. 2 Big-step operational semantics (most related) Slonneger and Kurtz Ch 8.4, 8.5, 8.6 Small-step operational semantics operational semantics also proved useful in work with Krzysztof Apt on count-able nondeterminism [4,5]. A realisation struck me around then. I, and others, were writing papers on denotational semantics, proving adequacy relative to an operational semantics.

Typically, these operations map one-to-one to operations defined in the RPC interface in xla_data.proto . A note on nomenclature: the generalized data type XLA deals with is an N-dimensional array holding elements of some uniform type (such as 32-bit float).
