File: psb_zspins.f90 ! ! Subroutine: psb_zspins ! Takes a cloud of coefficients and inserts them into a sparse matrix. ! Note: coefficients with a row index not belonging to the current process are ! ignored. ! If desc_a is in the build state this routine implies a call to psb_cdins. ! ! Parameters: ! nz - integer. The number of points to insert. ! ia(:) - integer The row indices of the coefficients. ! ja(:) - integer The column indices of the coefficients. ! val(:) - complex The values of the coefficients to be inserted. ! a - type(). The sparse destination matrix. ! desc_a - type(). The communication descriptor. ! info - integer. Error code ! rebuild - logical Allows to reopen a matrix under ! certain circumstances. ! subroutine psb_zspins(nz,ia,ja,val,a,desc_a,info,rebuild) use psb_tools_mod, psb_protect_name => psb_zspins use psb_descriptor_type use psb_spmat_type use psb_serial_mod use psb_const_mod use psb_error_mod use psb_penv_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 logical, intent(in), optional :: rebuild !locals..... integer :: nrow, err_act,mglob,ncol, spstate integer :: ictxt,np,me logical, parameter :: debug=.false. integer, parameter :: relocsz=200 logical :: rebuild_ integer, allocatable :: ila(:),jla(:) character(len=20) :: name, ch_err info = 0 name = 'psb_zspins' call psb_erractionsave(err_act) ictxt = psb_cd_get_context(desc_a) mglob = psb_cd_get_global_rows(desc_a) call psb_info(ictxt, me, np) if (.not.psb_is_ok_desc(desc_a)) 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 (nz==0) return if (present(rebuild)) then rebuild_ = rebuild else rebuild_ = .false. endif spstate = a%infoa(psb_state_) if (psb_is_bld_desc(desc_a)) then if (psb_is_large_desc(desc_a)) then allocate(ila(nz),jla(nz),stat=info) if (info /= 0) then ch_err='allocate' call psb_errpush(4013,name,a_err=ch_err,i_err=(/info,0,0,0,0/)) goto 9999 end if call psb_cdins(nz,ia,ja,desc_a,info,ila=ila,jla=jla) if (info /= 0) then ch_err='psb_cdins' call psb_errpush(4013,name,a_err=ch_err,i_err=(/info,0,0,0,0/)) goto 9999 end if nrow = psb_cd_get_local_rows(desc_a) ncol = psb_cd_get_local_cols(desc_a) if (spstate == psb_spmat_bld_) then call psb_coins(nz,ila,jla,val,a,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 call psb_cdins(nz,ia,ja,desc_a,info) if (info /= 0) then ch_err='psb_cdins' call psb_errpush(4013,name,a_err=ch_err,i_err=(/info,0,0,0,0/)) goto 9999 end if nrow = psb_cd_get_local_rows(desc_a) ncol = psb_cd_get_local_cols(desc_a) if (spstate == psb_spmat_bld_) then call psb_coins(nz,ia,ja,val,a,1,nrow,1,ncol,info,gtl=desc_a%glob_to_loc) 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 end if else if (psb_is_asb_desc(desc_a)) then if (psb_is_large_desc(desc_a)) then allocate(ila(nz),jla(nz),stat=info) if (info /= 0) then ch_err='allocate' call psb_errpush(4013,name,a_err=ch_err,i_err=(/info,0,0,0,0/)) goto 9999 end if ila(1:nz) = ia(1:nz) jla(1:nz) = ja(1:nz) call psb_glob_to_loc(ila(1:nz),desc_a,info,iact='I') call psb_glob_to_loc(jla(1:nz),desc_a,info,iact='I') nrow = psb_cd_get_local_rows(desc_a) ncol = psb_cd_get_local_cols(desc_a) call psb_coins(nz,ia,ja,val,a,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 nrow = psb_cd_get_local_rows(desc_a) ncol = psb_cd_get_local_cols(desc_a) call psb_coins(nz,ia,ja,val,a,1,nrow,1,ncol,& & info,gtl=desc_a%glob_to_loc,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 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 == psb_act_abort_) then call psb_error(ictxt) return end if return end subroutine psb_zspins
