Get current parallel pool
p = gcp returns a
parallel.Pool object representing the current parallel pool. The current pool is where parallel language features execute, such as
If no parallel pool exists,
gcp starts a new parallel pool and returns a pool object for that, unless automatic pool starts are disabled in your parallel preferences. If no parallel pool exists and automatic pool starts are disabled,
gcp returns an empty pool object.
p = gcp('nocreate') returns the current pool if one exists. If no pool exists, the
'nocreate' option causes
gcp not to create a pool, regardless of your parallel preferences settings.
Find Size of Current Pool
Find the number of workers in the current parallel pool.
p = gcp('nocreate'); % If no pool, do not create new one. if isempty(p) poolsize = 0; else poolsize = p.NumWorkers end
Delete Current Pool
Use the parallel pool object to delete the current pool.
