클러스터로 openfoam 하려고 하는데
라즈베리 / odroid c2로 다른 기종해서 해보려고 하고 있습니다
그래서 mpirun을 실행해보려고 하는데 라즈베리 파이는 잘 되는데
odroid c2는 mpirun만 실행해도 illegal instruction 에러가 발생합니다. (apt-get으로 설치)
strace를 통해 추적해보면 /proc/cpuinfo 이거나 geteuid() 아닐까 의심이 되는데
혹시 이런 경험을 해보신분 계시는지 궁금합니다.

It is possible that you forgot to specify how many processes to run
