Improving performance is a central concern for software developers. To locate optimization
opportunities, developers rely on software profilers. However, these profilers only report …

In multicore systems, contention for access to main memory between application threads
complicates timing analysis and may lead to pessimistic bounds on execution time. This is …

Software is everywhere, from mission critical systems such as industrial power stations,
pacemakers and even household appliances. This growing dependence on technology and …

Architectural heterogeneity is increasing: numerous products and studies have proven the
benefits of combining cores and accelerators with varying ISAs into a single system …

To understand, debug, and predict the performance of complex software systems, we
develop the concept of probabilistic performance annotations. In essence, we annotate …

We present HORNET, a parallel, highly configurable, cycle-level multicore simulator based
on an ingress-queued worm-hole router NoC architecture. The parallel simulation engine …

Current memory reclamation mechanisms for highly-concurrent data structures present an
awkward trade-off. Techniques such as epoch-based reclamation perform well when all …

This paper tries to identify waiting events that limit the maximal throughput of a multi-
threaded application. To achieve this goal, we not only need to understand an event's …

Program anomaly detection analyzes normal program behaviors and discovers aberrant
executions caused by attacks, misconfigurations, program bugs, and unusual usage …

In parallel programs, the tasks of a given application must cooperate in order to accomplish
the required computation. However, the communication time between the tasks may be …
