Hi Lara,
Please take a read of
http://ambermd.org/gpus/ which should hopefully tell you what you need to no. In short what you would do is:
cd run1
export CUDA_VISIBLE_DEVICES=0
$AMBERHOME/bin/pmemd.cuda -O -i ... &
cd ../run2
export CUDA_VISIBLE_DEVICES=1
$AMBERHOME/bin/pmemd.cuda -O -i ... &
cd ../run3
export CUDA_VISIBLE_DEVICES=2
$AMBERHOME/bin/pmemd.cuda -O -i ... &
All the best
Ross
