Bugs have been introduced into the lj/gpu potential in the main LAMMPS distribution; this needs to be updated. For GPU acceleration, please use the code at:

http://code.google.com/p/gpulammps/source/checkout

and read the new README in lib/gpu and documentation in doc/Section_start.html under running on GPUs as this has changed. If you still have problems, I can address them for this code.

Thanks. - Mike

Did you download the code with the svn checkout instructions from the site I provided? Is the root directory name for the distribution gpulammps? The code is not available from the main LAMMPS site.

Srinivas,

From your message, it looks like you didn’t try using the code at:

http://code.google.com/p/gpulammps/source/checkout

as Mike suggested. Would you mind trying this and letting us know?

Thanks,

Paul
