Sir,
We have installed amber12 in a GPU server. Test run fine.
On trying pmemd.cuda.MPI on a protein-ligand system. Its hanging on the
last line of the .out file i attached together. After half an hour (but
without showing any error) i terminated the run. the same with a dna-
ligand system. Please have a look at the .out file which includes all the
inputs given. And i am trying pmemd for the first time. Please give some
suggestions too.
"
The same .out file is given below:
