A variety of data parallel programming environments are available today, most widely used of which are: Message Passing Interface: It is a cross-platform message passing programming interface for parallel computers. It defines the semantics of library functions to allow users to write portable message passing programs in C, C++ and Fortran.
An accumulating snapshot table often has multiple date columns, each representing a milestone in the process. Therefore, it's important to have an entry in the associated date dimension that represents a placeholder for an unknown date, as many of the milestone dates are unknown at the time of the creation of the row.
Fields may be stored in a random access file. [7] A file may be written to or read from in an arbitrary order. To accomplish the arbitrary access, the operating system provides a method to quickly seek around the file. [8] Once the disk head is positioned at the beginning of a record, each file field can be read into its corresponding memory field.
