Hi @narendrachaudhary51 , You can review this pull request? Changes for Qtree building Kernel and Sort Kernel will be in a separate pull request.

@Pahandrovich The parallelization of the summarization kernel will not be beneficial without Qtree building. It might be same or slower then single threaded. This is due to irregular memory access. However, with the new tree building memory accesses become regular.
