It has some error in my code, but I can't find anything wrong with my code. EDA Playground says:
Execution interrupted or reached maximum runtime.
Here is my code:
forever #5 clk = ~clk;

Your testbench includes these lines:
forever
#5 clk = ~clk;
This code will keep executing forever. (The clue is in the syntax.) Therefore, your simulation will never stop. EDA Playground's maximum run time is 1 minute, so your simulation is killed after that. Hence your error message.
You need to stop this code executing when you are finished with it. You need something like this:
reg clk, clear, go;
...
initial
begin
go = 1'b1;
...
while (go)
#5 clk = ~clk;
end
initial begin
$dumpfile("systolic_array1.vcd");
$dumpvars(1,systolic_array);
#10
...
go = 1'b0;
end

another way is to use
$finish. initial #10000 $finish;
