Binary instrumentation frameworks are widely used to implement profilers, performance
evaluation, error checking, and bug detection tools. While dynamic binary instrumentation …

Ethereum smart contracts are programs that can be collectively executed by a network of
mutually untrusted nodes. Smart contracts handle and transfer assets of values, offering …

The locality metrics are many, for example, miss ratio to test performance, data footprint to
manage cache sharing, and reuse distance to analyze and optimize a program. It is unclear …

In this paper we present a profiling methodology and toolkit for helping developers discover
hidden asymptotic inefficiencies in the code. From one or more runs of a program, our …

Many opportunities for easy, big-win, program optimizations are missed by compilers. This is
especially true in highly layered Java applications. Often at the heart of these missed …

Understanding why the performance of a multithreaded program does not improve linearly
with the number of cores in a shared-memory node populated with one or more multicore …

Languages such as Java and C#, as well as scripting languages like Python, and Ruby,
make extensive use of Collection classes. A collection implementation represents a fixed …

Calling context enhances program understanding and dynamic analyses by providing a rich
representation of program location. Compared to imperative programs, object-oriented …

This paper defines a new analysis paradigm, blended program analysis, that enables
practical, effective analysis of large framework-based Java applications for performance …

As computer architectures become increasingly complex and heterogeneous, it becomes
progressively more difficult to write applications that make good use of hardware resources …
