I am receiving the same error and I am running OpenMP binaries in Gem5. I have found a patch for m5 not sure if it applies for gem5 as well or not? http://www.cs.virginia.edu/~jm6dg/fractal/smp.htm (Do you suggest this patch?) ./build/X86/gem5.opt ./configs/example/se.py --cpu-type=timing --num-cpus=8 --clock=4GHz --num-dirs=1 --l2_size=4MB --l1d_size=64kB --l1i_size=64kB -- num-l2caches=1 --l2_assoc=16 -c ./benchmarks/rodinia/bin/backprop -o 64 Global frequency set at 1000000000000 ticks per second 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7008 0: system.remote_gdb.listener: listening for remote gdb #1 on port 7009 0: system.remote_gdb.listener: listening for remote gdb #2 on port 7010 0: system.remote_gdb.listener: listening for remote gdb #3 on port 7011 0: system.remote_gdb.listener: listening for remote gdb #4 on port 7012 0: system.remote_gdb.listener: listening for remote gdb #5 on port 7013 0: system.remote_gdb.listener: listening for remote gdb #6 on port 7014 0: system.remote_gdb.listener: listening for remote gdb #7 on port 7015 **** REAL SIMULATION **** info: Entering event queue @ 0.
