labReceive

Receive data from another worker

Syntax

data = labReceive
data = labReceive(srcWkrIdx)
data = labReceive('any',tag)
data = labReceive(srcWkrIdx,tag)
[data,srcWkrIdx,tag] = labReceive


Arguments

srcWkrIdx	labindex of a particular worker from which to receive data.
tag	Tag defined by the sending worker’s labSend function to identify particular data.
'any'	Character vector to indicate that data can come from any worker.
data	Data sent by the sending worker’s labSend function.

Description

data = labReceive receives data from any worker with any tag.

data = labReceive(srcWkrIdx) receives data from the specified worker with any tag

data = labReceive('any',tag) receives data from any worker with the specified tag.

data = labReceive(srcWkrIdx,tag) receives data from only the specified worker with the specified tag.

[data,srcWkrIdx,tag] = labReceive returns the source worker labindex and tag with the data.

Tips

This function blocks execution in the worker until the corresponding call to labSend occurs in the sending worker.

Extended Capabilities

GPU Arrays

Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.

This function fully supports GPU arrays. For more information, see Run MATLAB Functions on a GPU.

If data is a gpuArray, data transfer between multiple GPUs in a parallel pool uses fast peer-to-peer communication, including NVLink, if available.
