title: Unified Parallel C - examples and list of extensions
body: <p>Where can I find examples of code, written in "Unified Parallel C"?</p>
  
  <p>I also interested in normative documents about this language (standards, reference manuals, online-accessible books and courses). What extensions were added to C to get UPC?</p>
  
  <p>Is this dialect alive or dead?</p>
