This is an internal function.
make_chunks(nelements, nworkers, scheduling = 1, chunk_size = NULL)(integer) Total number of elements to iterate over.
(integer) Number of workers available.
(numeric) A strictly positive scalar.
Only used if argument chunk_size is NULL.
(numeric) The maximum number of elements per
chunk, or NULL. If NULL, then the chunk sizes are given by the
scheduling argument.
A list of chunks, where each chunk is an integer vector of
unique indices in [1, nelements]. The union of all chunks
holds nelements elements and equals 1:nelements.
If nelements == 0, then an empty list is returned.
Attribute ordering of chunk_size or scheduling can
be used to control the ordering the elements are iterated over, which
only affects the processing order not the order values are returned.
This attribute can take the following values:
index vector - an numeric vector of length nelements specifying
how elements are remapped
function - an function taking one argument which is called as
ordering(nelements) and which must return an
index vector of length nelements, e.g.
function(n) rev(seq_len(n)) for reverse ordering.
"random" - this will randomize the ordering via random index
vector sample.int(nelements).
