What happens if the number of workers vacant are less than the minimum value in the specified range of SPMD?

spmd (m,n)
    <statements>
end

If n workers aren't available, it is mentioned in the document that the statement would wait until enough workers are available. What would happen if m workers aren't available? Will it wait for at least m workers to be available?

The spmd reference page states:

spmd(m,n), statements, end uses a minimum of m and a maximum of n workers to evaluate statements. If there are not enough workers available, an error is thrown. m can be zero, which allows the block to run locally if no workers are available.

So, if m workers are not available, an error will be thrown.
