Hello Dear Mr. Lin,
I just wanted to ask if there had been any progress on this issue that
you know of? It seems to persist through to
amber18, many in my research group are using this module and would be
glad for any update on the issue.
Best regards
Paul Westphälinger

I was in the modifying my scripts around to making it work due to the code changes between amber14 vs amber16 (Primarily because I use cuda 8.0 and some of the assembly functions originally built for amber 14 became intrinsics when cuda 8.0 came around.). If the memory hit is there I was going to take a look at whether or not the allocation of the COMs code was correct or not first. This also gives you a diff to look at in terms of changes that might have caused the errors (The amber update files are essentially diff files so if you want to apply them individually you can download them and do a "patch -p0 < updatefile" command. http://ambermd.org/bugfixes14.html). If you want we can speak off the mailing list about this.
