  Cerium is parallel programming framework developed by C++.
  Describe Task-Dependency for parallel computing.
  Task-Dependency can't ensure data correctness.
  Task parameters has no type information for the use of untyped pointer.
  Wrong type cast will produce undefined results.
  Object-oriented programming(OOP) is incompatible with parallel computing.
  Continuation based C(CbC) is programming language which uses Code Segment.
  Use Code Segment as a unit of parallel computing.
  We are developing Gears OS using Code/Data Segment.
  Parallelism in a high performance Gears OS with Code/Data Segment.
  We show same implementation of Gears OS using CbC.
  Gears OS implementation is a guide to programming using Code/Data Segment.
