Hi,

The patch command should create a reject file: blabla.rej.
So look for files with a rej extension.
Also since in bugfix 11 there are only a few files to be patched in
src/pmemd/src/cuda, you could look at those files to see if the
patch has been applied:
http://ambermd.org/bugfixes/11.0/bugfix.11
