Implicit And Explicit Parallelism

Implicit Parallelism

• This approach uses c, c++, forton, pascal to write the source program.   
• Sequentially coded program is translated in to parallel object by a parallelizing compiler.
• The system will do the the parallelism in our code.

Explicit parallelism:

• The programmer requires more effort to develop a source program using c, c++, forton or pascal.
• Parallelism is explicitly specified in the user program.
• This reduces the burden on the compiler to detect parallelism and target machine resources.
