he model was compiled with <code>STAN_THREADS=true</code>, the chains can run in parallel, with the <code>num_threads</code> argument
defining the maximum number of threads used to run the chains. If the model uses no within-chain parallelization
(<code>map_rect</code> or <code>reduce_sum</code> calls), the below command will run 4 chains in parallel, provided there are cores
available:</p>
<pre><code>./bernoulli sample num_chains=4 data file=bernoulli.data.json output file=output.csv num_threads=4</code></
