Hi all, I am trying to run BFS benchmark from the GAP benchmark suite (https://github.com/sbeamer/gapbs) using GEM5 SE. If I use an input graph with up to 16 million vertices everything works fine. However, when I use an input graph with more than 16 million vertices I obtain the following error: **** REAL SIMULATION **** src/sim/simulate.cc:194: info: Entering event queue @ 0.  Starting simulation... src/sim/syscall_emul.cc:85: warn: ignoring syscall set_robust_list(...)       (further warnings will be suppressed) src/sim/mem_state.cc:443: info: Increasing stack size by one page. src/sim/syscall_emul.cc:74: warn: ignoring syscall mprotect(...) src/sim/mem_state.cc:443: info: Increasing stack size by one page. src/sim/mem_state.cc:443: info: Increasing stack size by one page.

On my machine the benchmark runs correctly. Has anyone ever had similar problems using relatively large workloads? PS. I'm aware that I'm using the old "se.py," but I believe this is not the cause of the problem. Thank you in advance, Mirco Mannino
