Passwordless SSH install for Intel® Parallel Studio XE Cluster Edition

I have established secure shell (SSH) connectivity on my cluster where each node has a public key. However, when I use any secure shell utility on the cluster, I am still prompted for a password. What am I doing wrong?

  • Ordering of images on different nodes using Coarray Fortran and IntelMPI

    Hello

    I have a question about ordering of images when -coarray=distributed compiler option is used and the program is run on a cluster using IntelMPI libraries.

    Assuming that the number of images is the same as the number of CPUs, are the images running on CPUs within the same node indexed by consecutive numbers?

  • Intel MPI issue with the usage of Slurm

    To whom it may concern,

    Hello. We are using Slurm to manage our Cluster. However, we met a new issue of Intel MPI with Slurm. When one node reboots, the Intel MPI will fail with that node but manaully restart of slurm daemon will fix it. I also tried to add "service slurm restart" in /etc/rc.local which runs in the end of booting but the issue is still there.
