Dear Aljoscha and Ufuk, Thank you for clarifying! Yes I'm running this wordcount application on a 64-core machine with 120GB ram allocated for users.

Definitely I will try this! The result will be really interesting for sure. In this case, am I still good to go with 64 task slots with a single task manager? Thank you. With best regards, Shinhyung Yang.
