It is now well established that the device scaling predicted by Moore's Law is no longer a
viable option for increasing the clock frequency of future uniprocessor systems at the rate …

Efficient tracing of system-wide execution, allowing integrated analysis of both kernel space
and user space, is something difficult to achieve. The following article will present you a new …

K42 is an open-source, Linux-compatible, scalable operating-system kernel that can be
used for rapid prototyping of operating-system policies and mechanisms. This paper reviews …

Hardware performance counters (HPCs) are increasingly being used to analyze
performance and identify the causes of performance bottlenecks. However, HPCs are …

Adaptive, or self-aware, computing has been proposed to help application programmers
confront the growing complexity of multicore software development. However, existing …

As the complexity of computing systems increases, application programmers must be
experts in their application domain and have the systems knowledge required to address the …

With the growing awareness that individual hardware cores will not continue to produce the
same level of performance improvement, there is a need to develop an integrated approach …

This paper presents a finding and a technique on program behavior prediction. The finding
is that surprisingly strong statistical correlations exist among the behaviors of different …

Virtual machines for languages such as the Java programming language make extensive
use of online profiling and dynamic optimization to improve program performance. But …

Accurately predicting program behaviors (eg, locality, dependency, method calling
frequency) is fundamental for program optimizations and runtime adaptations. Despite …
