TimingSimpleCPU does not deadlock. I'm running on the develop branch without modification. Here is the configuration I'm running: ./build/X86/gem5.opt configs/example/se.py --cmd=/path/to/app --num-cpus=16 --cpu-type=DerivO3CPU --caches --l2cache --l1d_size=64kB --l1i_size=16kB --l2_size=4MB --mem-type=DDR3_1600_8x8 My application spawns 16 pthreads, and the threads perform atomic arithmetic operations and use pthread barriers. From what I can tell, the issue is that on one of the barriers only one or two threads are ever woken up once all threads are ready. When running with the above configuration, the simulation just hangs. When I run with ruby caches, the simulation eventually terminates from the Sequencer panicking on "Possible Deadlock detected." Are pthread barriers not currently supported? I tried using m5threads, but as per this issue (https://github.com/gem5/m5threads/issues/2), I can't compile it with my gcc and kernel versions. I would greatly appreciate any help with this issue.
