labBarrier

Block execution until all workers reach this call

Syntax

labBarrier

Description

labBarrier blocks execution of a parallel algorithm until all workers have reached the call to labBarrier. This is useful for coordinating access to shared resources such as file I/O.

Examples

Synchronize Workers for Timing

When timing code execution on the workers, use labBarrier to ensure all workers are synchronized and start their timed work together.

labBarrier;
tic
    A = rand(1,1e7,'codistributed');
distTime = toc;
