... many processors can manipulate the data in the nodes of the data structure in parallel. Each processor in the CM can have its own local variables. These variables are called parallel variables, ... implementing parallel nat- ural language programs on real hardware has clarified which operations and programming techniques are the most efficient and useful. Programs that build upon general algorithms ... or parallel fields. When a host computer program per- forms a serial operation on a parallel variable, that op- eration is performed separately in each processor in the CM. For example, a...
