ZPL ...
Is an array language
-- whole arrays are manipulated with primitive operations
•Requires
new thinking strategies --
•Forget
one-operation-a-time scalar programming
•Think of the computation globally -- make the global
logic work
efficiently and leave the details to the compiler
•Is
parallel, but there are no parallel constructs in the language; the
compiler...
•Finds
all concurrency
•Performs
all interprocessor communication
•Implements
all necessary synchronization (almost none)
•Performs
extensive parallel and scalar optimizations
