Using Statement-Level Parallelism

Using Statement-Level Parallelism

As noted under "Statement-Level Parallelism", you can use statement-level parallelism in three language packages: Fortran 77, Fortran 90, and C. This type of parallelism is unique in that you begin with a normal, serial program, and you can always return the program to serial execution by recompiling. Every other parallel model requires you to plan and write a parallel program from the start.

The parallel features of all three of these languages are documented in detail in the manuals listed in Table 3-2.

In addition to these products from Silicon Graphics, Inc., the High Performance Fortran (HPF) compiler from the Portland Group is a compiler for Fortran 90 augmented to the HPF standard. It supports automatic parallelization. (Refer to http://www.pgroup.com for more information).

The FORGE products from Applied Parallel Research (APRI) contain a Fortran 77 source analyzer that can insert parallelizing directives, although not the directives supported by MIPSpro Fortran 77. (Refer to http://www.infomall.org/apri for more information.)
