Composite
Create Composite object
Syntax
C = Composite()
C = Composite(nlabs)
Description
C = Composite() creates a Composite object on the client using workers from the
parallel pool. The actual number of workers referenced by this Composite object depends
on the size of the pool and any existing Composite objects. Generally, you should
construct Composite objects outside any spmd statement.
C = Composite(nlabs) creates a Composite object on the parallel pool set that
matches the specified constraint. nlabs must be a vector of length 1 or 2, containing
integers or Inf. If nlabs is of length 1, it specifies the exact number of workers to use. If
nlabs is of size 2, it specifies the minimum and maximum number of workers to use. The
actual number of workers used is the maximum number of workers compatible with the
size of the parallel pool, and with other existing Composite objects. An error is thrown if
the constraints on the number of workers cannot be met.
A Composite object has one entry for each lab; initially each entry contains no data. Use
either indexing or an spmd block to define values for the entries.
Tips
• A Composite is created on the workers of the existing parallel pool. If no pool exists,
Composite starts a new parallel pool, unless the automatic starting of pools is
disabled in your parallel preferences. If there is no parallel pool and Composite
cannot start one, the result is a 1-by-1 Composite in the client workspace.
