Re: [ESPResSo-users] Configuration file for building Espresso with LB

[Owen Hickey]

Hello Edith,

The message indicates that no GPU capable of running CUDA code was
detected. The easiest way to solve this is to run configure with the
option --without-cuda. The LB is much faster on a GPU but if you don't
have one available the CPU version is an alternative.

Good luck,

Owen
