This report does not provide enough information for us to be of any
help. (It basically just says "an error occurred").
It's worth (a) re-running the calculation on a different machine, if
possible, to see if you always get the same problem; (b) examining the
output to see if there are any clues, such as bad or unusual energies,
that help help; (c) running a short version of the simulation on the
CPU, since error messages on CPU's are often more helpful than those on
GPUs.
....good luck....dac
