</h3>
<p>We are using a spawning mechanism in multicore processing. Each
worker processor gets a copy of the required data and libraries. In case
of limited available memory and a large dataset, you can reduce the
number of CPU cores (nthread) to fit the processing into your system.
Following this recommendation, the processing time will increase;
however, the memory usage will decrease.</p>
