Hi, We have been trying to run MPI jobs (consisting of two different binaries, one each ) in two nodes, using hostfile option as following
mpirun --allow-run-as-root --mca pml yalla -n 1 --hostfile /root/host1 /root/app2 : -n 1 --hostfile /root/host2 /root/backend We are doing this in chroot environment. We have set the HPCX env in chroot'ed environment itself. /root/host1 and /root/host2 (inside chroot env) contains IPs of two nodes respectively. We are getting following error " all nodes which are allocated for this job are already filled " However when we use chroot but don't use hostfile option (both processes run in same node) OR we use hostfile option but outside chroot, it works. Anyone has any idea if chroot can cause above error and how to solve it ? Thanks Rahul
