Common Subexpression Elimination in Dotty

Martin Odersky, Dmytro Petrashko, Allan Vincent Roger Renucci

Common subexpression elimination is a well-known compiler optimisa- tion that improves running time of compiled applications by avoiding the repetition of the same computation. Although it has been implemented on a low level such as bytecode, it misses mul ...

RRB Vector: A Practical General Purpose Immutable Sequence

Martin Odersky, Tiark Rompf, Nicolas Alexander Stucki, Vlad Ureche

State-of-the-art immutable collections have wildly differing performance characteristics across their operations, often forcing programmers to choose different collection implementations for each task. Thus, changes to the program can invalidate the choice ...

Isolates, channels, and event streams for composable distributed programming

Martin Odersky, Aleksandar Prokopec

The actor model has been a model of choice for building reliable distributed systems. On one hand, it ensures that message-processing is serialized within each actor, preserving the familiar sequential programming model. On the other hand, programs written ...

Effects as Implicit Capabilities

Martin Odersky

We propose to investigate a new approach to effect checking that has an elegant solution to the effect polymorphism problem. The central idea is that instead of talking about effects we talk about capabilities. For instance, instead of saying a function “t ...

ScalaDyno: Making Name Resolution and Type Checking Fault-tolerant

Martin Odersky, Vlad Ureche, Cédric Bastin

The ScalaDyno compiler plugin allows fast prototyping with the Scala programming language, in a way that combines the benefits of both statically and dynamically typed languages. Static name resolution and type checking prevent partially-correct code from ...

Spiral in Scala: Towards the Systematic Construction of Generators for Performance Libraries

Martin Odersky, Tiark Rompf, Alen Stojanov

Program generators for high performance libraries are an appealing solution to the recurring problem of porting and optimizing code with every new processor generation, but only few such generators exist to date. This is due to not only the difficulty of t ...

Functional programming (FP) is regularly touted as the way forward for bringing parallel, concurrent, and distributed programming to the mainstream. The popularity of the rationale behind this viewpoint (immutable data transformed by function application) ...

Type errors reported by compilers can sometimes be cryptic, or difficult to understand. In this paper, we propose a type debugging framework that exposes a high-level representation of the typechecking decision-making process that users normally do not hav ...

Delite: A Compiler Architecture for Performance-Oriented Embedded Domain-Specific Languages

Martin Odersky, Tiark Rompf, Hassan Chafi

Developing high-performance software is a difficult task that requires the use of low-level, architecture-specific programming models (e.g., OpenMP for CMPs, CUDA for GPUs, MPI for clusters). It is typically not possible to write a single application that ...

Yin-Yang: Concealing the Deep Embedding of DSLs

Martin Odersky, Christoph Koch, Amir Shaikhha, Sandro Stucki, Vojin Jovanovic, Vladimir Nikolaev

Deeply embedded domain-specific languages (EDSLs) intrinsically compromise programmer experience for improved program performance. Shallow EDSLs complement them by trading program performance for good programmer experience. We present Yin-Yang, a framework ...
