threadBegin¶
Purpose¶
Marks the beginning of a multi-line block of code to be executed as a thread.
Format¶
threadBegin;
Examples¶
threadBegin;
m = n*p;
n = calcA(m);
threadEnd;
Notice that the writer-must-isolate rule (see Multi-Threaded Programming in GAUSS)
does not apply within the bounds of the threadBegin
/threadEnd
pair, as there is no risk of
simultaneous access to a symbol. The rule only applies between the threads in a given set (and their children).
See threadJoin
for an example of a fully-defined thread set.
