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 labs:

spmd
    P = codistributor1d.defaultPartition(10)
end
