Q. What is Program Annotation Packages?
A quite renowned scheme in this field is OpenMP a newly designed industry standard for shared memory programming on architectures with uniform memory access features. OpenMP is based on functional parallelism and concentrates mainly on the parallelisation of loops. OpenMP applications use a special compiler to evaluate annotations in application's source code and to transform code in an explicitly parallel code that can then be implemented. Shared memory scheme offers low level management of shared memory system however they tends to be error prone and tedious. They are more appropriate for system programming than to application programming.
