failed Kevin S. Wed, 10/29/2014 - 19:37 Hello, I am running Intel MPI for Intel mp_linpack benchmark (xhpl_em64t). Steps: 1. I sourced the mpivars.sh from /opt/intel/impi/bin64/mpivars.sh 2. I did "mpdboot -f hostfile" $ cat hostfile node 1 node 23. I did "mpirun -f hostfile -ppn 1 -np

2 ./xhpl_em64t" After step 3, errors occured.

Their hardware is identical, and they are running CentOS 7. I'm using Intel's cluster compiler and MPI implementation. Everything is setup: I can ssh between all the nodes without a password, and I've shared the /opt directory with nfs, so http://serverfault.com/questions/648317/intel-mpi-gives-channel-initialization-failed-error-mpirun which mpicc and which mpirun succeeds on all nodes. mpirun -hosts node1 -n 24 /home/cluster/test is the command I'm trying to run (test is compiled from test.c from the Intel compiler's test directory and is nfs shared between all nodes). It works fine on any single node, but if I try to run it across more than one node, I get: [cluster@headnode ~]$ mpirun -hosts headnode -n 10 /home/cluster/test Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(784)...................: MPID_Init(1323).........................: channel initialization failed MPIDI_CH3_Init(141).....................: MPID_nem_tcp_post_init(644).............: MPID_nem_tcp_connect(1107)..............: MPID_nem_tcp_get_addr_port_from_bc(1342): Missing ifname or invalid host/port description in business card Google has not given me any useful answers.

MPI calls: Impact of Pthread core affinity on MPI over Infiniband Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi Amirul, The port on the IB HCA is still in an Initializing http://mailman.cse.ohio-state.edu/pipermail/mvapich-discuss/2013-December/004730.html state. This could probably be because opensmd service is not running or has to http://stackoverflow.com/questions/31057694/gethostbyname-fail-after-switching-internet-connections be restarted. The "State" field for the connected port should show "Active" once this is fixed.

Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(498)..............: MPID_Init(187).....................: channel initialization failed MPIDI_CH3_Init(89).................: MPID_nem_init(320).................: MPID_nem_tcp_init(171).............: MPID_nem_tcp_get_business_card(418): MPID_nem_tcp_init(377).............: gethostbyname failed, MacBook-Pro.local (errno 1) Everything works fine in the coffee shop, and then when I come home, I get the above error. Nothing else has changed. I've checked the /etc/hosts and /private/etc/hosts files, and they look okay - ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost I can ping localhost, so the problem isn't exactly that localhost isn't resolved. Rebooting always fixes the problem, but is there something simple I can do to "reset" my system so that it recognizes local host? I don't have access to the details of the MPI initialization routines in the code I am running and am not making any explicit calls to gethostname. I am using MPICH 3.1.4 (built Feb,
