parfevalOnAll

Execute function asynchronously on all workers in parallel pool

Syntax

F = parfevalOnAll(p,fcn,numout,in1,in2,...)

F = parfevalOnAll(fcn,numout,in1,in2,...)

Description

F = parfevalOnAll(p,fcn,numout,in1,in2,...) requests the asynchronous

execution of the function fcn on all workers in the parallel pool p, expecting numout

output arguments from each worker and supplying input arguments in1,in2,... to

each worker. F is a parallel.FevalOnAllFuture object, from which you can obtain the

results when all workers have completed executing fcn.

F = parfevalOnAll(fcn,numout,in1,in2,...) requests asynchronous execution

on all workers in the current parallel pool. If no pool exists, it starts a new parallel pool,

unless your parallel preferences disable automatic creation of pools.

Examples

Close all Simulink models on all workers.

p = gcp(); % Get the current parallel pool

f = parfevalOnAll(p,@bdclose,0,'all');

% No output arguments, but you might want to wait for completion

wait(f);
