MULTITHREADING

"Multithreading is a widespread programming and execution model that allows multiple threads to exist within the context of a single process. These threads share the process's resources, but are able to execute independently."

SOURCE: http://en.wikipedia.org/wiki/Multithreading_(software)#Multithreading


motivation


  • Complementary related threads
  • Utilise spare DaSH-cycles
  • Each coordinated
  • Other threads,  e.g. data and management?
  • Strategy - others that should know?



yarn for the thread 

"Computers"


  • Where have they come from?
  • Where are they now?
  • Where are they going?
