! Subroutine writes restart snapshot, i.e. parameters, meta and data blocks
! to the HDF5 format restart files in order to resume a terminated job later.
! Subroutine stores restart snapshots in the HDF5 format.

! Arguments:
!
! problem - the problem's name;
! nrun - the snapshot number;
! iret - the return flag to inform if subroutine succeeded or failed;
! status - the subroutine call status;
