You should try to dig in what exactly happened with the simulation.
The error printed seems to point that the application did something
wrong. It is trying to read from an address it should not.

Yes you are right. I had infact used the quotes but missed it in the mail,
sorry about that. But even with that, I get the same error.
Also they parsing is working fine as I printed out the names of the
executables being signed to each thread.
Thanks for looking into this.

your command line should use encapsulate your SMT commands in

separate command on the shell.

Hi,
The configs/example/se.py script has a small error that does not allow
proper workload assignment to SMT threads. I made the following changes to
fix that part:

I am simulating X86 with detailed core. The simulation aborts with the
following error:

Any ideas of what might be going wrong ? I'd be happy to provide more
debug information. Thanks for your help !
