.. _neuron-runtime-faq: NeuronX runtime FAQ ================== .. contents:: Table of Contents :local: :depth: 1 Where can I find information about Neuron Runtime 2.x (``libnrt.so``) --------------------------------------------------------------------- See :ref:`introduce-libnrt` for detailed information about Neuron Runtime 2.x (``libnrt.so``). What will happen if I will upgrade Neuron Framework without upgrading latest kernel mode driver? ------------------------------------------------------------------------------------------------ Application start would fail with the following error message: .. code:: bash 2021-Aug-11 19:18:21.0661 24616:24616 ERROR NRT:nrt_init This runtime requires Neuron Driver version 2.0 or greater. Please upgrade aws-neuron-dkms package. Do I need to recompile my model to use the Runtime Library? ----------------------------------------------------------- No. Runtime 2.x supports all the models compiled with Neuron Compiler 1.x. Do I need to change my application launch command? -------------------------------------------------- No. How do I restart/start/stop the NeuronX Runtime? ----------------------------------------------- Since Neuron Runtime is a library, starting/stopping application would result in starting/stopping the Neuron Runtime. How do I know which runtimes are associated with which Neuron Device(s)? ------------------------------------------------------------------------ `neuron-ls` and `neuron-top` can be used to find out applications using Neuron Devices. What about RedHat or other versions of Linux and Windows? -------------------------------------------------------- We don't officially support it yet. How can I take advantage of multiple NeuronCores to run multiple inferences in parallel? --------------------------------------------------------------------------------------- Examples of this for TensorFlow and MXNet are found :ref:`here ` and :ref:`here `.
