WebDSL: Linguistic Abstractions for Web Programming

Information systems store and organize data, and manage business processes concerned with that data. Information systems aim to support operations, management and decision-making in organizations. Web applications are ideal for implementing information systems. Although existing web frameworks provide abstractions for creating web applications,...

Accelerating Programmer-Friendly Intermittent Computing

The Internet of Things (IoT) is taking the world by storm, from smart lights to smart plant monitoring. This revolution is not only present in consumers’ homes, but companies are also looking for more and more ways to monitor every aspect of their production process. This transition to ubiquitous monitoring is made possible by extremely low...

Compiler Assisted Reliability Optimizations

Microprocessors are used in an expanding range of applications from small embedded system devices to supercomputers and mainframes. Moreover, embedded microprocessor based systems became essential in modern societies. Depending on the application domain, embedded systems have to satisfy different constraints. The major challenges today are cost,...

Automatic Hardware Generation for Reconfigurable Architectures

Reconfigurable Architectures (RA) have been gaining popularity rapidly in the last decade for two reasons. First, processor clock frequencies reached threshold values past which power dissipation becomes a very difficult problem to solve. As a consequence, alternatives were sought to keep improving the system performance. Second, because Field...

Language-parametric Techniques for Language-Specific Editors

The goal of this dissertation is to develop techniques that simplify the implementation of tool support for new languages. More specifically, we focus on language-parametric solutions for the implementation of language-specific editor support. In the first part of this dissertation we investigate generic techniques to recover from syntax errors...

Automated computational modelling for complicated partial differential equations

In engineering, physical phenomena are often described mathematically by partial differential equations (PDEs), and a commonly used method to solve these equations is the finite element method (FEM). Implementing a solver based on this method for a given PDE in a computer program written in source code can be tedious, time consuming and error...

Automated Solution of Partial Differential Equations with Discontinuities using the Partition of Unity Method

Although computers were invented to automate tedious and error-prone tasks, computer programming is a tedious and error-prone task itself. This is a well-known paradox in the field of computational mathematical modelling. Recently, automatic code generation has been proposed to solve this paradox. In this approach, a required code to model...

Compiler Assisted Runtime Adaptation

In this dissertation, we address the problem of runtime adaptation of the application to its execution environment. A typical example is changing theprocessing element on which a computation is executed, considering the available processing elements in the system. This is done based on the information and instrumentation provided by the compiler...

K-loops: Loop Transformations for Reconfigurable Architectures

The focus of this dissertation is on kernel loops (K-loops), which are loop nests that contain hardware mapped kernels in the loop body. In this thesis, we propose methods for improving the performance of such K-loops, by using standard loop transformations for exposing and exploiting the coarse grain loop level parallelism. We target a...

Recursive variable expansion: A transformation for reconfigurable computing

Reconfigurable computing, in which general purpose processor (GPP) is augmented with one or more FPGAs, is increasingly used for high-performance computing where massive fine-grain parallelism and pipelining can be exploited. A challenge is to exploit such massive parallelism on FPGAs and more specifically how to map an application on the...

The Molen compiler for reconfigurable architectures

In this dissertation, we present the Molen compiler framework that targets reconfigurable architectures under the Molen Programming Paradigm. More specifically, we introduce a set of compiler optimizations that address one of the main shortcomings of the reconfigurable architectures, namely the reconfiguration overhead. The proposed...

Compiler Strategies for Transport Triggered Architectures

Compiler technology plays an important role to enhance the performance of modern microprocessors. In this thesis, compiler techniques and strategies are described to enhance the performance of microprocessors based on the Transport Triggered Architecture. The interaction between two important phases in a compiler, instruction scheduling and...
