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

This paper presents Spectral Profiling, a new method for profiling program execution without
instrumenting or otherwise affecting the profiled system. Spectral Profiling monitors EM …

This paper presents an approach for zero-overhead profiling (ZOP). ZOP accomplishes
accurate program profiling with no modification to the program or system during profiling and …

Calling contexts are very important for a wide range of applications such as profiling,
debugging, and event logging. Most applications perform expensive stack walking to …

Faults that occur in production systems are the most important faults to fix, but most
production systems lack the debugging facilities present in development environments …

Path profiles provide a more accurate characterization of a program's dynamic behavior than
basic block or edge profiles, but are relatively more expensive to collect. This has limited …

Modern processors are hungry for instructions. To satisfy them, compilers need to find and
optimize execution paths across multiple basic blocks. Path profiles provide this context, but …

Micro architectures increasingly rely on dynamic optimization to improve performance in
ways that are difficult or impossible for ahead-of-time compilers. Dynamic optimizers in turn …

Dynamic binary modification tools form a software layer between a running application and
the underlying operating system, providing the powerful opportunity to inspect and …

Leveraging side-channels enables zero-overhead detection of anomalies. These channels
offer a non-instrumented program profiling capability by means of the distinct signatures …
