11 C | Parallel directives to generate multithreaded code for
12 C | various different compilers. The master preprocessor
13 C | file CPP_OPTIONS is used to select which of these options
14 C | is included in the code.
15 C | Note: Only some of the directives require end blocks.
16 C | For directives which do not require end blocks there
17 C | is no entry here.

22 C--
23 C-- Parallel directives for Kuck and Associates compiler.
24 C-- This is used to generate multi-threaded code on Digital
25 C-- systems. It can also be used under NT.
26 C-- Note: The KAP parallel proceesing tool has several bugs
27 C-- which means that if there are more threads (set via
28 C-- setenv PARALLEL) than iterations in the parallel
29 C-- loop the extra threads start on the section
30 C-- after the loop!
31 C-- To work around this we could place an extra dummy
32 C-- parallel section here. KAP places a barrier at the
33 C-- start of each parallel region which ensures that
34 C-- the extra threads wait (note this wait is in a busy loop).
35 C-- Without this feature the extra thread(s) will run on and may
36 C-- halt the program by calling STOP! Unfortunately that seems
37 C-- to cause a deadlock in a KAP library routine! Instead the
38 C-- current solution is to check for a thread reaching the
39 C-- shutdown part of main.F before other threads have
40 C-- completed computation ( see eedie.F ).
