Since benchmarks drive computer science research and industry product development,
which ones we use and how we evaluate them are key questions for the community. Despite …

Developers frequently use inefficient code sequences that could be fixed by simple patches.
These inefficient code sequences can cause significant performance degradation and …

Performance bugs are programming errors that create significant performance degradation.
While developers often use automated oracles for detecting functional bugs, detecting …

Many popular cloud applications are large-scale distributed systems with each request
involving tens to thousands of RPCs and large code bases. Because of their scale …

When creating architectural tools, it is essential to know whether the generated results make
sense. Comparing a toolpsilas outputs against hardware performance counters on an actual …

Competing workloads on a shared storage system cause I/O resource contention and
application performance vagaries. This problem is already evident in today's HPC storage …

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

Inter-application I/O contention and performance interference have been recognized as
severe problems. In this work, we demonstrate, through measurement from Titan (world's …

A fundamental part of developing software is to understand what the application spends time
on. This is typically determined using a performance profiler which essentially captures how …

Often, the only sources of information about the evolution of software systems are the
systems themselves and their histories. Version control repositories contain information on …
