endp

endp

end process

Code: F3

Description: Synchronize the termination of a parallel construct. When all branches

have executed an endp instruction a ‘successor’ process then executes. Areg points

to the workspace of this successor process. This workspace contains a data structure

which holds the instruction pointer of the successor process and the number of

processes still active.

Definition:

if (word[Areg @ pp.Count] = 1)

{

Iptr′ ← word[Areg @ pp.IptrSucc]

Wptr′ ← Areg

}

else

word′[Areg @ pp.Count] ← word[Areg @ pp.Count]−1

start next process

Areg′ ← undefined

Breg′ ← undefined

Creg′ ← undefined

Error signals: none

Comments:

Secondary instruction.

Instruction is a descheduling point.
