nnp-predict

Hi,

I just noticed that nnp-predict can only predict one configuration for each time, is it possible to predict multiple configurations in input.data at once? For example, I want to check the accuracy of NNPs to predict some (e.g., 100 configs) testing configurations, it is inconvenient to use nnp-predict one by one. Many thanks for your help in advance.

Cheers,
zezhu

Hello!

That's what the tool nnp-dataset is good for, e.g. like this:

mpirun -np 16 nnp-dataset 0

This will compute the predictions for all structures in input.data while distributing the work onto 16 MPI tasks. The 0 argument tells it not to shuffle the structures internally. Enabling this with 1 may yield better load balancing but the output order will then also be randomized.

Best,
Andreas
