[AMBER] Speed issue with Accelerated molecular dynamics.

Hi!

     I am trying to preform aMD on a system.
     I was getting 8.06 ns/day using classical MD. When i tried using aMD,
the speed dropped to 6.38 ns/day.
     My system has 238234 atoms (i.e. ~.2 million).
     I am using TIP3P water in a box with periodic boundaries.
     Protein being simulated is a dimer.
     I am using a K20 GPU card for this simulation.
     I am unable to understand why this speed drop happened when it should
accelerate and what can be done to fix this.
     Please advice.


Regards

Abhilash
