Feedback-Directed Metamorphic Testing
ACM Transactions on Software Engineering and Methodology, 2023Over the past decade, metamorphic testing has gained rapidly increasing attention from both academia and industry, particularly thanks to its high efficacy on revealing real-life software faults in a wide variety of application domains. On the basis of a set of metamorphic relations among multiple software inputs and their expected outputs, metamorphic

Optimal Direct Velocity Feedback
Applied Mathematics and Computation, 2013We present a novel approach to the problem of Direct Velocity Feedback (DVF) optimiza- tion of vibrational structures, which treats simultaneously small as well as large gains. For that purpose, we use two different approaches. The first one is based on the gains optimization using the Lyapunov equation.

Feedback directed optimization of TCMalloc
Proceedings of the workshop on Memory Systems Performance and Correctness, 2014TCMalloc [9] is an open-source memory allocator. Its use of thread-local caches of free objects enables most allocations/deallocations to be satisfied from thread-local heaps not requiring locks, making it a highly scalable memory allocator for multi-threaded applications.

ParTool: A Feedback-Directed Parallelizer
2011We present a tool which gives detailed feedback to application developers on how their programs can be made amenable to parallelization. Also, the tool automatically parallelizes the code for a large number of constructs. Since the tool outputs a parallelized code with OpenMP pragmas, the feedback cycle can be run any number of times till the desired ...

Feedback-Directed Random Test Generation
29th International Conference on Software Engineering (ICSE'07), 2007We present a technique that improves random test generation by incorporating feedback obtained from executing test inputs as they are created. Our technique builds inputs incrementally by randomly selecting a method call to apply and finding arguments from among previously-constructed inputs.

Feedback-directed specialization of code
Computer Languages, Systems & Structures, 2010Based on feedback information, a large number of optimizations can be performed by the compiler. This information actually indicates the changing behavior of the applications and can be used to specialize code accordingly. Code specialization is a way to facilitate the compiler to perform optimizations by providing the information regarding variables ...

Feedback directed implicit parallelism
ACM SIGPLAN Notices, 2007In this paper we present an automated way of using spare CPU resources within a shared memory multi-processor or multi-core machine. Our approach is ( i ) to profile the execution of a program, ( ii ) from this to identify pieces of work which are promising sources of parallelism, (
