3.3 Combined Automatic and Directed Parallelization Using the kf77 Driver

Use a combination of automatic and directed parallelization on a large program where you want to control parallization of a small number of loops, but you want KAP to control parallelization of the remaining loops.

To cause KAP to perform both automatic and directed parallelization, use the the -concurrentize switch and the correct compiler and linker switches for your version of DIGITAL UNIX on the kf77 command line.

Insert PCF directives around those loops you want to parallelize explicitly. KAP does directed parallelization on the loops enclosed with PCF directives and automatic parallelization on the remaining program.

In the following command line example, myprog_pcf.f contains PCF directives:

kf77 -fkapargs='-conc' myprog_pcf.f
