When the ThreadedGenerateData() function is called in an itk filter, the threads refer to the number of CPUs on a computer or the number of cores on each CPU. <br><br>For example, <span style="white-space:pre"> </span>i have 8 cpus on my laptop with 4 cores on each, so if I call SetNumberOfThreads(4), these 4 cores will belong to the same CPU ? <br><br>On the next lever, if I divide the work on each cpu and then also do multithreading in each CPU, will the number of threads correspond to the number of cores on each CPU ?<br>Thanks a lot for any insight..<br><br>Vikash<br><br></div></body></html>
