The maturation of the Web platform has given rise to sophisticated and demanding Web
applications such as interactive 3D visualization, audio and video software, and games. With …

Virtual machines face significant performance challenges beyond those confronted by
traditional static optimizers. First, portable program representations and dynamic language …

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

Performance for the Java™ Platform has evolved in stages. Early VM's were interpreter-only.
Later VM's were interpreter plus template generated code, and finally interpreter plus …

The efficient implementation of behaviorally reflective languages imposes a formidable
challenge. By definition, behavioral reflection allows a program to modify, even at run-time …

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

Version 6 of Sun Microsystems' Java HotSpot™ VM ships with a redesigned version of the
client just-in-time compiler that includes several research results of the last years. The client …

Instrumenting code to collect profiling information can cause substantial execution
overhead. This overhead makes instrumentation difficult to perform at runtime, often …

Researchers are actively exploring techniques to enforce control-flow integrity (CFI), which
restricts program execution to a predefined set of targets for each indirect control transfer to …

Arbitrary program extension at run time in language-based VMs, eg, Java's dynamic class
loading, comes at a startup cost: high memory footprint and slow warmup. Cloud computing …
