= PDAF_set_memberid = 

This page documents the routine `PDAF_set_memberid` of PDAF. The routine was introduced with PDAF 2.0.

The routine allows a user to reset the ensemble member counter inside PDAF. This routine should only be used in the flexible parallelization mode, thus when `PDAF_put_state_X` is used. Resetting the member counter, allows e.g. to enforce the execution of the analysis step in the case, when according to the PDAF-internal counter, the ensemble integration is not yet complete. For this, one has to specify the member-ID to be the ensemble size.

To just enforce an analysis step, we recommend to use the routine [wiki:PDAF_force_analysis]. This routine is also compatible with `PDAF_assimilate_X`.

[[span(style=color: #FF0000, '''Warning:''' This is a routine for advanced functionality of PDAF. Use it carefully, since it can break the assimilation process.)]]

The interface is the following:
{{{
  SUBROUTINE PDAF_set_memberid(member)
}}}
without the argument:
 * `member`: `integer, intent(in)` Member in index to which the PDAF-internal counting is reset.
