The HPFF was convened and chaired by Ken Kennedy of Rice University.
Building on the array syntax introduced in Fortran 90, HPF uses a data parallel model of computation to support spreading the work of a single array computation over multiple processors.
The updated report removed material which was already covered by Fortran 95.
While some vendors did incorporate HPF into their compilers in the 1990s, some aspects proved difficult to implement and of questionable use.
For example, the BIT data type proposal for the Fortran-2008 standard contained a number of new intrinsic functions taken directly from HPF.
