Dear users I want to run a quantum espresso program (with passwordless ssh). I prepared a hostfile named 'texthost' at my input directory. I get this error when I run the program:
texthost: # This is a hostfile. # I have 4 syetems are paralleled by mpich2 # The following nodes are that machines I want to use: #clie...@master.cluster.umz slots=4 khal...@client1.cluster.umz slots=4 max-slots=4 #khal...@client2.cluster.umz slots=4 max-slots=4 khal...@client3.cluster.umz slots=8 max-slots=8 command: mpirun --host texthost -np 2 /home/client3/espresso-5.0.2/bin/pw.x -in AdnAu.rx.in | tee AdnAu.rx.out error: ssh: Could not resolve hostname texthost: Name or service not known after press ctrl+c: ^C[mpie...@master.cluster.umz] HYDU_sock_write (./utils/sock/sock.c:291): write error (Bad file descriptor) [mpie...@master.cluster.umz] HYD_pmcd_pmiserv_send_signal (./pm/pmiserv/pmiserv_cb.c:170): unable to write data to proxy [mpie...@master.cluster.umz] ui_cmd_cb (./pm/pmiserv/pmiserv_pmci.c:79): unable to send signal downstream [mpie...@master.cluster.umz] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status [mpie...@master.cluster.umz] HYD_pmci_wait_for_completion (./pm/pmiserv/pmiserv_pmci.c:197): error waiting for event [mpie...@master.cluster.umz] main (./ui/mpich/mpiexec.c:331): process manager error waiting for completion Could you help me please?
