NTAUPAR = [integer] 

Default: NTAUPAR = depends on MAXMEM used in low scaling GW and RPA/ACFDT calculations.

Description: NTAUPAR available as of VASP.6, specifies the number of MPI groups sharing same imaginary time grid points. The default value of NTAUPAR is set automatically and depends on MAXMEM, the available memory for each rank on one node.
