File: psb_zspins.f90 ! ! Subroutine: psb_zspins ! Takes a cloud of points and inserts them into a sparse matrix. ! ! Parameters: ! nz - integer. The number of points to insert. ! ia - integer,dimension(:). The row indices of the points. ! ja - integer,dimension(:). The column indices of the points. ! val - real,dimension(:). The values of the points to be inserted. ! a - type(). The sparse destination matrix. ! desc_a - type(). The communication descriptor. ! info - integer. Eventually returns an error code. ! is - integer(optional). The row offset. ! js - integer(optional). The column offset. ! subroutine psb_zspins(nz,ia,ja,val,a,desc_a,info,is,js,rebuild) use psb_descriptor_type use psb_spmat_type use psb_serial_mod use psb_const_mod use psb_error_mod implicit none !....parameters... type(psb_desc_type), intent(inout) :: desc_a type(psb_zspmat_type), intent(inout) :: a integer, intent(in) :: nz,ia(:),ja(:) complex(kind(1.d0)), intent(in) :: val(:) integer, intent(out) :: info integer, intent(in), optional :: is,js logical, intent(in), optional :: rebuild !locals..... integer :: i,icontxt,nprocs ,glob_row,row,k,start_row,end_row,& & first_loc_row,nrow,j, err,locix,locjx,err_act,& & dectype,mglob, nnza,m,n, pnt_halo,ncol, nh, ip, spstate integer,pointer :: tia1(:),tia2(:), temp(:) integer :: nprow,npcol, myrow ,mycol, iflag, isize, irlc logical, parameter :: debug=.false. integer, parameter :: relocsz=200 logical :: rebuild_ interface psb_cdins subroutine psb_cdins(nz,ia,ja,desc_a,info,is,js) use psb_descriptor_type implicit none type(psb_desc_type), intent(inout) :: desc_a integer, intent(in) :: nz,ia(:),ja(:) integer, intent(out) :: info integer, intent(in), optional :: is,js end subroutine psb_cdins end interface character(len=20) :: name, ch_err info = 0 name = 'psb_zspins' call psb_erractionsave(err_act) icontxt = desc_a%matrix_data(psb_ctxt_) dectype = desc_a%matrix_data(psb_dec_type_) mglob = desc_a%matrix_data(psb_m_) ! check on blacs grid call blacs_gridinfo(icontxt, nprow, npcol, myrow, mycol) if (npcol.ne.1) then info = 2030 call psb_errpush(info,name) goto 9999 endif if (.not.psb_is_ok_dec(dectype)) then info = 3110 call psb_errpush(info,name) goto 9999 endif if (nz <= 0) then info = 1111 call psb_errpush(info,name) goto 9999 end if if (size(ia) < nz) then info = 1111 call psb_errpush(info,name) goto 9999 end if if (size(ja) < nz) then info = 1111 call psb_errpush(info,name) goto 9999 end if if (size(val) < nz) then info = 1111 call psb_errpush(info,name) goto 9999 end if if (present(rebuild)) then rebuild_ = rebuild else rebuild_ = .false. endif spstate = a%infoa(psb_state_) if (psb_is_bld_dec(dectype)) then call psb_cdins(nz,ia,ja,desc_a,info) if (info /= 0) then info=4010 ch_err='psb_cdins' call psb_errpush(info,name,a_err=ch_err) goto 9999 end if nrow = desc_a%matrix_data(psb_n_row_) ncol = desc_a%matrix_data(psb_n_col_) if (spstate == psb_spmat_bld_) then call psb_coins(nz,ia,ja,val,a,desc_a%glob_to_loc,1,nrow,1,ncol,info) if (info /= 0) then info=4010 ch_err='psb_coins' call psb_errpush(info,name,a_err=ch_err) goto 9999 end if else info = 1123 call psb_errpush(info,name) goto 9999 end if else if (psb_is_asb_dec(dectype)) then nrow = desc_a%matrix_data(psb_n_row_) ncol = desc_a%matrix_data(psb_n_col_) call psb_coins(nz,ia,ja,val,a,desc_a%glob_to_loc,1,nrow,1,ncol,& & info,rebuild=rebuild_) if (info /= 0) then info=4010 ch_err='psb_coins' call psb_errpush(info,name,a_err=ch_err) goto 9999 end if else info = 1122 call psb_errpush(info,name) goto 9999 end if call psb_erractionrestore(err_act) return 9999 continue call psb_erractionrestore(err_act) if (err_act.eq.act_abort) then call psb_error(icontxt) return end if return end subroutine psb_zspins
