Composite

Access nondistributed variables on multiple workers from client

Constructor

Composite

Description

Variables that exist on the workers running an spmd statement are accessible on the client as a Composite object. A Composite resembles a cell array with one element for each worker. So for Composite C:

C{1} represents value of C on worker1
C{2} represents value of C on worker2
etc.

spmd statements create Composites automatically, which you can access after the statement completes. You can also create a Composite explicitly with the Composite function.

Methods

exist	Check whether Composite is defined on workers
gather	Transfer distributed array, Composite array or gpuArray to local workspace
subsasgn	Subscripted assignment for Composite
subsref	Subscripted reference for Composite

Other methods of a Composite object behave similarly to these MATLAB^® array functions:

disp	Display Composite
end	Indicate last Composite index
isempty	Determine whether Composite is empty
length	Length of Composite
ndims	Number of Composite dimensions
numel	Number of elements in Composite
size	Composite dimensions
