DIRAC

Users running the DIRAC RELCCSD module should be aware that they must use the following configuration in their inputs:

**RELCC
.INTERFACE
DIRAC6

If they also use the MOLTRA module in their CCSD (or CCSD(T) or FSCC) calculations, they must also add the following lines:

**MOLTRA
.SCHEME
6
.HTSORT
1

Given the high data transfer load that the current (since DIRAC-23.0) default scheme (SCHEME4) implies in Hábrók, we ask all DIRAC users who use these features to include the aforementioned variables in their input files. More information can be found here and here.
