Backend.AI agent kernels in various programming languages / toolkits and frameworks.
Here we list the latest versions of our supported kernel images. "*" in the Query mode column means that it supports preservation of global contexts across different query runs.

Since Backend.AI v19.03, the kernel-runner component are completely separated from the kernel images as they are mounted at runtime by the agent.
All you need to do for a new kernel is specifying a set of Backend.AI-specific labels and preparation of the jail policy.
ai.backend.kernelspec: For now, it's set to "1".ai.backend.features: A list of constant strings indicating which Backend.AI kernel features are available for the kernel.- batch: Can execute user programs passed as files.
- query: Can execute user programs passed as code snippets while keeping the context across multiple executions.
- uid-match: As of 19.03, this must be specified always.
- user-input: The query/batch mode supports interactive user inputs.
ai.backend.resource.min.*: The minimum amount of resource to launch this kernel. At least, you must define the CPU core (cpu) and the main memory (mem). In the memory size values, you may use binary scale-suffixes such asmforMiB,gforGiB, etc.ai.backend.base-distro: Either "ubuntu16.04" or "alpine3.8". Note that Ubuntu 18.04-based kernels also need to use "ubuntu16.04" here.ai.backend.runtime-type: The type of kernel runner to use. (One of the directories in theai.backend.kernelnamespace.)ai.backend.runtime-path: The path to the language runtime executable.ai.backend.service-ports: A list of 3-tuple strings specifying services available via network tunneling. Each tuple consists of the service name, the service type (one of pty, http, or tcp) and the container-side port number. Backend.AI manages the host-side port mapping and network tunneling via the API gateway automagically.ai.backend.envs.corecount: The list of environment variables to be set as the number of available CPU cores to the container. This is for legacy parallel computation libraries.
Note that the implementation of query/batch modes, runtime-type and service-ports are the responsibility of the kernel runner in the agent codebase. For most computation kernels based Python (e.g., Anaconda, NVIDIA GPU Cloud, etc.) may simply reuse the implementation and labels from the standard "python" image.
Currently we support two major base Linux distros, Ubuntu and Alpine.
