[AMBER] simulating with "gbsa=1" on gpu give only 0.18ns per/day

Hi everyone,


I am trying to do (GB/SA) calculation with intrinsic water model. In my simulation I also want to include surface area so I was planning to use "gbsa=1" .

As I am running on GPU I am getting only 0.18ns per day only, bust as soon I am removing "gbsa=1" I am getting decent speed of 10ns per day.


So simulating while use "gbsa=1" seems to be impossible.

Can anyone suggest me what should I do?


This is my script

  imin=0,irest=1,ntx=5,
  nstlim=10000000,dt=0.001,
  ntf=2,ntc=2,ntb=0,
  igb=8,gbsa=1,cut=9999.0,rgbmax=15.0,
  ntpr=500, ntwx=500, ntwr=10000,
  saltcon=0.2,
  temp0=300.0,
  ntt=1,tautp=1.0,
  nscm=0,




Thanking you,

Abhishek
