Query: Proceedings 5th Workshop on Programming Language Approaches to
  Concurrency and Communication-cEntric Software   PLACES 2013 (full title: Programming Language Approaches to Concurrency- and
Communication-cEntric Software) was the sixth edition of the PLACES workshop
series. After the first PLACES, which was affiliated to DisCoTec in 2008, the
workshop has been part of ETAPS every year since 2009 and is now an established
part of the ETAPS satellite events. This year, PLACES was the best attended
workshop at ETAPS 2013.
  The workshop series was started in order to promote the application of novel
programming language ideas to the increasingly important problem of developing
software for systems in which concurrency and communication are intrinsic
aspects. This includes software for multi- and many-core systems, accelerators
and large-scale distributed and/or service-oriented systems. The scope of
PLACES includes new programming language features, whole new programming
language designs, new type systems, new semantic approaches, new program
analysis techniques, and new implementation mechanisms.
