SQL & PL/SQL

Hi All,
Is it possible to call two separate Functions ( independent from each other) in parallel (Like in Java, using Threads).
I've a requirement of calling two(or more) Functions. Currently I am doing it serially however are independent to each other.
The snippet of code is like -

For chk in Cursor1
Loop
EXECUTE IMMEDIATE 'begin : 0 :=' || g_check_master (chk.check_id).exec_prog || '(:1 ,:2, :3, :4, :5); end;'
USING OUT l_ret_val
, IN pi_report_request_id
, IN g_check_master (chk.check_id).mapped_col_in_rep_sum
, IN pi_user_cec_id
, OUT po_err_code
, OUT po_err_msg;
IF (l_ret_val = pk_snme_constants.gc_failure) THEN
---do something 1
else
---do something 2
END IF;
end loop;
---------------------------------------------------------------------------------
g_check_master contains all the function names. Content of cursor1 will decide how many functions are to be called.
Pls guide if I can do it in parallel somehow?
