codistributor1d.defaultPartition

Default partition for codistributed array

Syntax

P = codistributor1d.defaultPartition(n)

Description

P = codistributor1d.defaultPartition(n) is a vector with sum(P) = n and

length(P) = numlabs. The first rem(n,numlabs) elements of P are equal to ceil(n/

numlabs) and the remaining elements are equal to floor(n/numlabs). This function

is the basis for the default distribution of codistributed arrays.

Examples

If numlabs = 4, the following code returns the vector [3 3 2 2] on all workers:

spmd

P = codistributor1d.defaultPartition(10)

end
