Re: [AMBER] CUDA and Restraint Error

update.7 for AMBER v18 addresses this problem. I am not sure if there is a patch for v16 to fix this issue, somebody from the GPU code developers team will need to confirm.

I am having trouble running restrained MD simulation with pmemd.cuda on

Just to be sure: have you installed all updates, especially update.7,
which addresses problems in using COM restraints in pmemd.cuda? Go
to $AMBERHOME, and type "./update_amber --help" for information, and
"./update_amber --update" to get your code up to date. Then, re-run
configure and make.
