      Hi vijay, thank you for the feedback. About DNS , no right example hitting my mind at this moment. I will keep the question in mind and will post it when I found something more suitable to your question.

    Hi Ramdev,
    Do you have any article regarding Infiniband on Linux. I am interested on this topic. Also if you have something on HPC (High Performance Computing), that will be good also.
