WebHigh-Performance Fortran (HPF) was created as an extension of Fortran 90 with constructs that support parallel computing, Some HPF capabilities and constructs were incorporated in Fortran 95. The implementation of HPF features was uneven across vendors and OpenMP attracts vendors to better support OpenMP over HPF features. WebARRAY: Shall be an array of type INTEGER, REAL or COMPLEX.
