Re: [AMBER] Error: invalid configuration argument launching kernel kPMEFillChargeGridBuffer

Good morning,

after testing the installation, the error is still appearing in every
CUDA execution of the user's input but not with the CPU version of
Amber14 or previous versions of Amber with CUDA. Any hint about how to
avoid it or what else can I check?

Many thanks,
Pablo.
