This probably means that one (or more) of your cores was not running. > > > When the number of instructions is increased, then i got the following > result: > =========================================================== > warn: Increasing stack size by one page. > warn: Increasing stack size by one page. > warn: Increasing stack size by one page. > Exiting @ cycle 56291500 because target called exit() > ============================================================= This implies that the target application (assuming you are in system emulation mode) called exit.

Is your scheduler assigning a thread to each core? You might want to try Full System mode as you wont has the physical memory problem and can use traditional scripts. > > devraj > > > ------------------------------------------------------------------------ > > _______________________________________________ > m5-users mailing list > [email protected] > http://m5sim.org/cgi-bin/mailman/listinfo/m5-users _______________________________________________ m5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/m5-users
