New page

Multi-threading is only possible in the '''Commercial Edition'''.

Threads are represented by the <vp>thread</vp> class/interface. And it is very simple to create a new thread:

<vip>clauses
...
T = thread::start(myThread), % start a new thread which executes the predicate myThread
...

predicates
myThread : ().
clauses
myThread() :-
...</vip>

Using anonymous predicates it is also very simple to transfer data to the new thread:

<vip>clauses
...
SomeData = ...,
T = thread::start( { :- myThreadWithData(SomeData) }),
...

predicates
myThreadWithData : (complexData ThreadInputData).
clauses
myThreadWithData(ThreadInputData) :-
...</vip>

You can wait for thread termination, because a thread object is a synchronization object:

<vip>clauses
...
SomeData = ...,
T = thread::start( { :- myThreadWithData(SomeData) } ),
... % stuff done in parallel with T
T:wait(), % Wait for T to terminate
...</vip>

Thread safe acces to shared data can be done using [[Language Reference/Monitors|monitors]] and/or synchronization objects like <vp>criticalSection</vp>, <vp>event</vp>, <vp>mutex</vp> and <vp>semaphore</vp>.
