illegal instruction (CPU mismatch)

[Mahmood Naderan]

I ran the command from the compute node. I also set the number of the threads to 1.

mahmood@compute-0-1:tran-bt-o-40$ ulimit -c unlimited
mahmood@compute-0-1:tran-bt-o-40$ gdb --args /share/apps/siesta/openmpi-2.0.0/bin/mpirun -hostfile hosts.txt -np  sc.sh

So, please see the output

Do you have any idea? Still I am not able to see the illegal instruction
