mpirun 에 host 기재하기

% mpirun -host node1,node1,node2,node2 ...

mpirun 에 hostfile로 지정하기

% cat my_hosts
a slots=2 max_slots=20
b slots=2 max_slots=20
c slots=2 max_slots=20
d slots=2 max_slots=20

Suppose you issue the following command to run program a.out:


% mpirun -np 1 --hostfile my_hosts --host c a.out
