Building high-performance virtual machines is a complex and expensive undertaking; many
popular languages still have low-performance implementations. We describe a new …

Most high-performance dynamic language virtual machines duplicate language semantics
in the interpreter, compiler, and runtime system. This violates the principle to not repeat …

Effect handlers are a program structuring paradigm with rising popularity in the functional
programming language community and can express many advanced control flow …

The Java Virtual Machine (JVM) has been widely adopted in part because of its classfile
format, which is portable, compact, modular, verifiable, and reasonably easy to work with …

While event-driven programming is a widespread model for asynchronous computing, its
inherent control flow fragmentation makes event-driven programs notoriously difficult to …

The Ruby programming language is dynamically typed, uses dynamic and late bound
dispatch for all operators, method calls and many control structures, and provides extensive …

Coroutines are non-preemptive lightweight processes. Their advantage over threads is that
they do not have to be synchronized because they pass control to each other explicitly and …

Sampling profilers are popular because of their low and adjustable overhead and because
they do not distort the profile by modifying the application code. A typical sampling profiler …

Contemporary concurrent server applications, commonly built of smaller and independent
services, are using concurrent threads to serve many incoming requests and often have to …

In this paper, we describe the Eureka Programming Model (EuPM) that simplifies the
expression of speculative parallel tasks, and is especially well suited for parallel search and …
