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?

  • Installation

    On Linux* OS: After unpacking the Intel® Trace Collector archive in a folder of your choice read the file relnotes.txt for information on how to install Intel® Trace Collector.

    On Microsoft Windows* OS: run the installation file setup.exe and follow the instructions given in the installation wizard.

    Single-process Tracing

    Traces of just one process can be generated with the libVTcs library, which allows the generation of executables that work without MPI.

    Linking is accomplished by adding libVTcs.a (VTcs.lib on Microsoft* Windows* OS) and the libraries it needs to the link line:

    -lVTcs $VT_ADD_LIBS

    Analyzing the Results

    For interactive debugging the application has to be started so that stderr is printed to a console window. Then one can follow which errors are found while the application is running and start analyzing them without having to wait for it to complete. If critical errors are found early on one could even abort the run, fix the problem and restart. This ensures a much faster code and test cycle than a post-mortem analysis.

    Datatype Handling

    (LOCAL:DATATYPE)

    Unfreed data types can cause the same problems as unfreed requests, so the same kind of leak report is generated for them when their number exceeds CHECK-MAX-DATATYPES. However, because not freeing data types is common practice there is no leak report during finalize unless their number exceeds the threshold at that time. That is in contrast to requests which are always reported then.
