When I specify only -H like so: mpirun -H localhost -np 1 prog1 : -H A.lan -np 4 prog2 : -H B.lan -np 4 prog2 I get the same error: "There are not enough slots available in the system to satisfy the 4 slots that were requested by the application: prog2 Either request fewer slots for your application, or make more slots available for use". > Also, do you have at least 4 cores on both A.lan and B.lan ?

Re: [OMPI users] mpirun works with cmd line call , but not with app context file arg
Out of curiosity, why do you specify both --hostfile and -H ? Do you observe the same behavior without --hostfile ~/.mpihosts ? Also, do you have at least 4 cores on both A.lan and B.lan ?

[OMPI users] mpirun works with cmd line call , but not with app context file arg
Hi, openmpi 1.10.3 this call: mpirun --hostfile ~/.mpihosts -H localhost -np 1 prog1 : -H A.lan -np 4 prog2 : -H B.lan -np 4 prog2 works, yet this one: mpirun --hostfile ~/.mpihosts --app ~/.mpiapp doesn't. where ~/.mpiapp -H localhost -np 1 prog1 -H A.lan -np 4 prog2 -H B.lan -np 4 prog2 it says "There are not enough slots available in the system to satisfy the 4 slots that were requested by the application: prog2 Either request fewer slots for your application, or make more slots available for use". ___ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
