 Parallelize the specified loops. When multiple loop specifiers are passed
 as parameters, there loops can be parallelized as a collapsed loop.
 krnl.parallel should be placed as the last operator before krnl.iterate,
 Since we do not want to parallelize the loop until we interpret krnl.block,
 krnl.permute and krnl.unroll.
+
+Optionally, a value may specifiy the number of threads requested for the
+parallel loop. A proc_bind string may also be specified; valid values are
+"primary", "close", or "spread". Default values are used when not specified.
