/* ERROR/WARNING messages:

E: Insufficient memory on accelerator

There is insufficient memory on one of the devices specified for the gpu
package

E: Cannot use newton pair with eam/alloy/gpu pair style

Self-explanatory.

E: Incorrect args for pair coefficients

Self-explanatory.  Check the input script or data file.

E: No matching element in EAM potential file

The EAM potential file does not contain elements that match the
requested elements.

E: Cannot open EAM potential file %s

The specified EAM potential file cannot be opened.  Check that the
path and name are correct.

E: Incorrect element names in EAM potential file

The element names in the EAM file do not match those requested.
