The first ACM Workshop on Challenges in Performance Methods for Software Development was held in Austin, Texas, on Jan. 31 2015, and was co-located with the 2015 ACM/SPEC International Conference on Performance Engineering (ICPE). Its purpose was to open up new avenues of research on methods for software developers to address performance problems. The software world is changing, and there are new challenges. As its name implies, the workshop includes the description of problems as well as solutions. The acronym WOSP-C also recalls the original discussion-heavy format of WOSP, the ACM International Workshop on Software and Performance, which has been a co-organizer of ICPE since 2010.
