how long have you let it run? perhaps the java startup time is significant when running in simulation mode so it will take some time to get the ball rolling.
Try running: ./start_sim; java HelloWorld; ./stop_sim And just let it go ... if you get to the stop, then you know that the HelloWorld program ran successfully On Sat, Apr 16, 2011 at 11:15 PM, Zhe Wang <[email protected]> wrote: > Hi, > > The ptlsim keep printing the status update into the logfile like: > Completed 44560000 cycles, 40828598 commits: 134494 Hz, > 171620 insns/sec: rip ffffffff81050178 > > But on the QEMU screen, it freeze like: > > root@ubuntu:~# ./start_sim; > > Switching to simulation > ptlsim_ptlcall_init: Mapped Ptlcall MMIO page at phys 0x8ffff000, virt > 0x7fabc927b000 > > root@ubuntu:~# java HelloWorld > > > There are no "Hello, World" output as it supposed to be.
