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?

  • Recording Hardware Performance Information

    On Linux* OS, the Intel® Trace Collector can sample hardware counters with the Performance Application Programming Interface (PAPI). Because PAPI might not be available on a system, support for it is provided as an additional layer on top of the normal Intel® Trace Collector.

    This layer is implemented in the VT_sample.c source file. It is a sample file that traces counters available through PAPI High level API.

    To record hardware counters, do the following:

    Initialize and Finalize

    The application has to bootstrap the communication between the VTserver and its clients. This is done as follows:

    1. The application server initiates its processes.

    2. Each process calls VT_clientinit().

    3. VT_clientinit() allocates a port for TCP/IP communication with the VTserver or other clients and generates a string which identifies the machine and this port.
