[s2;%% This class is indented as loop`-parallelization tool. Whenever
|
|
loop iterations are independent (they do not share any data),
|
|
CoWork can be used to relatively easily spawn loop iterations
|
|
over thread and thus over CPU cores. CoWork works with fixed`-size
|
|
global thread pool, which is created during initialization phase
|
|
(first CoWork constructor called). No more thread are created
|
|
or destroyed during normal work. Nesting of CoWork instances
|
|
is also possible. Of course, not only loop iterations can be
|
|
parallelized, whenever there are two or more actions that can
|
|
run in parallel, you can use CoWork.&]
