Behavior of RCTD multi-cores

[WuRAFY]

Firstly, thanks for the great tool. When I run RCTD with max_cores=8, I found that RCTD initiated 8 jobs and each job occupied multiple cores. Actually, RCTD occupied all cores available (50 in taotal) even I limit the max number cores. Can you help?

Much thanks, FY
