Hi Trinayan,
I'm not aware of any deadlock/livelock bugs that would cause this. Is you simulation getting to a GPU kernel launch? It could be an issue with the GPU pipeline, something in SE mode, or the Ruby protocol. A trace would be useful to help you identify the source of the problem. The following flags may be useful: For the GPU: --debug-flags=GPUALL For the protocol: --debug-flags=ProtocolTrace,Ruby For syscalls: --debug-flag=SyscallAll --ExecAll may also be useful for the CPU's execution trace.

First of all the simulation hangs. After I check the simout, I see some open calls failing when trying to load some libraries. Maybe the hang is because of this. But the surprising thing is that these libraries are not on my system at all. Things like libhsa-ext-finalize64.so.1, libhsa-ext-image64.so.1 , libhsa-amd-aqlprofile64.so.1 namely. I am not sure how to get these because they were not installed when I installed the components required for the simulator. Could you let me know how to resolve this? Thank you. Best, Trinayan
