Hello,
I am trying to run the blackscholes program from the PARSEC2.1 benchmark suite
in QEMU SPARC user mode.
In this case I am trying to run with just 2 threads. Unfortunately, when I try
to run the program it hangs with the following prints:
HELPME: /mada/users/cromom/ESESC_PROJECT/esesc/emul/qemu1/target-sparc/cpu.h:516
HELPME: /mada/users/cromom/ESESC_PROJECT/esesc/emul/qemu1/target-sparc/cpu.h:516
I also turned on the print_syscall prints and have the attached the debugging
output below.
This problem can be reproduced by running the following command from within the
blackscholes sparc-linux directory(which I can provide) referencing the local
qemu installation:
/qemu/sparc-linux-user/qemu-sparc blackscholes 2 input_file output_file
Thank you for your help,
David
