getCodistributor
Codistributor object for existing codistributed array
Syntax
codist = getCodistributor(D)
Description
codist = getCodistributor(D) returns the codistributor object of codistributed
array D. Properties of the object are Dimension and Partition for 1-D distribution; and
BlockSize, LabGrid, and Orientation for 2-D block cyclic distribution. For any one
codistributed array, getCodistributor returns the same values on all workers. The
returned codistributor object is complete, and therefore suitable as an input argument for
codistributed.build.
Examples
Get the codistributor object for a 1-D codistributed array that uses default distribution on
4 workers:
spmd (4)
I1 = eye(64,codistributor1d());
codist1 = getCodistributor(I1)
dim = codist1.Dimension
partn = codist1.Partition
end
Get the codistributor object for a 2-D block cyclic codistributed array that uses default
distribution on 4 workers:
spmd (4)
I2 = eye(128,codistributor2dbc());
codist2 = getCodistributor(I2)
blocksz = codist2.BlockSize
partn = codist2.LabGrid
