Categories: General Date: Mar 1, 2018 Title: Liu and Wang Present at 38th ACM SIGPLAN Conference on PLDI 2018
UTSA assistant professors of computer science Dr. Tongping Liu and Dr. Wei Wang recently submitted a paper to be published in the 38th ACM SIGPLAN Conference on Programming Language Design and Implementation (PLDI) proceedings.
PLDI is the premier forum for researchers, developers, practitioners, and students in the design and implementation of Programming Language. Their paper, titled “iReplayer: In-situ and Identical Record-and-Replay for Multithreaded Applications,” aims to identically replay multithreaded programs in the original process, under the in-situ setting.
The novel in-situ and identical replay makes IdealReplay more likely to reproduce errors, and allows it to directly employ debugging mechanisms (e.g. watchpoints) to aid failure diagnosis. IdealReplay implements multiple methods to reduce its performance and support identical replay.
Currently, IdealReplay only incurs around 3% performance overhead, which allows it to be always enabled in the production environment. It will enable a range of possibilities, such as automatic failure analysis and error prevention.
PLDI 2018 will take place June 20-22 in Philadelphia, Pennsylvania.
