I try to use "addstripe" command to add power net on ALPA,but its run so long(>24h),the detial as follows:

%setAddStripeMode -ignore_DRC true -respect_routes all -skip_via_on_pin {Pad Block Cover Standardcell Physicalpin} -skip_via_on_wire_shape {blockring stripe followpin corewire blockwire iowire padring ring fillwire noshape } -spacing_from_block 5

%addstripe -nets {VDD VSS} -layer ALPA -direction horizontal -width 10 -spacing 5 -number_of_sets 10  -set_to_set_distance 150 -start_from bottom -start_offset 242 -switch_layer_over_obs false -max_same_layer_jog_length 2 -padcore_ring_top_layer_limit ALPA  -padcore_ring_top_layer_limit TM2  -block_ring_top_layer_limit ALPA  -block_ring_bottom_layer_limit TM2 -use_wire_group 0 -snap_wire_center_to_grid None

I guess some options I choose cause this dilemma?

By the way I have  exculded the influence of insufficient computing resources.

I will very appreciate it if someone can give me advise, thanks a lot.
