Hi, I'm trying to run multiworkload smt. I an the hello world program from tests, and I see that one of the outputs is displayed after m5exit. What is the reason for this?
./build/X86/gem5.opt ./configs/example/se.py --smt --cpu-type=DerivO3CPU --caches -c tests/test-progs/hello/bin/x86/linux/hello;tests/test-progs/hello/bin/x86/linux/hello gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Oct 10 2019 16:33:12 gem5 started Oct 17 2019 20:49:36 command line: ./build/X86/gem5.opt ./configs/example/se.py --smt --cpu-type=DerivO3CPU --caches -c tests/test-progs/hello/bin/x86/linux/hello Global frequency set at 1000000000000 ticks per second warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes) 0: system.remote_gdb: listening for remote gdb on port 7000 **** REAL SIMULATION **** info: Entering event queue @ 0. Starting simulation... Hello world! Exiting @ tick 16684000 because exiting with last active thread context Hello world! I assume its because m5exit occurs as soon as one thread is complete, and doesn't wait for the other one. Is there any workaround for this?

N = 33, 31 qubits required Random seed: 5 N = 33, 31 qubits required Random seed: 5 warn: MOVNTDQ: Ignoring non-temporal hint, modeling as cacheable! So I think that the problem is not in the way I framed the command. However, It has its own issue. OS: Ubuntu 18.04 gem5 version: a3d2a9ec92ad4406ccf51ff45a4a1d2aa16eaa69
