NAMD-CUDA GPU workload

Dear NAMD users,

I was running simulation on an 70,000-atom system of an ion channel (KcsA)
using NAMD 2.12 for Win64-multicore-CUDA on a desktop with an AMD 8-core
CPU and a GTX-1080 graphic card by:

"NAMD2 +p8 kcsa.conf > kcsa.log". I noticed that the workload of GPU was
only ~20% during the whole simulation process. I am wondering if there was
any way I could increase the workload of GPU to accelerate simulation.

Thanks for your help.
