BB_REDIRECTION equivalent in NOMAD 4 #101

Open unlusoycan opened 1 year ago

unlusoycan commented 1 year ago

I see that the BB_REDIRECTION parameter in NOMAD 3 is deprecated in NOMAD 4. I would like my own black box to handle the output file writing. I do this in NOMAD 3 by setting BB_REDIRECTION no. How can I communicate this setting in NOMAD 4?

The documentations mentions that black boxes may write output files, but I cannot find how to do it in the linked Advanced functionalities section.

This feature is not yet available in Nomad 4.

The part of the documentation mentioning that blackboxes may write output file is not up to date (copied from Nomad 3).

I think I also just now encountered this issue:

  1. The blackbox program must return the evaluation values by displaying them in the standard output (default) or by writing them in an output file (see Advanced functionalities about advanced output options).

Quote from here.

I am also looking for my blackbox to write evaluation values to a specific file and for NOMAD essentially ignore the blackbox standard out/err.

This feature is now implemented and will be available in the next release 4.4. The release will be available in November.
