Dear NAMD user
I am using NAMD platform for MD simulations. I want to use the GPU nodes on
the HPC with 4 GPU V100 and 24 cores

when i run the command
/namd2 +p24 +decvices 0,1

the Benchmark Days/ns is .01,
then I compared the simulation output performance with 4GPU
  /namd2 +p24 +decvices 0,1 ,2,3

  I got the same !!

it looks very poor performance for me

anyone can help me i can utilize this HPC

Lamya :)
