-------------------------------
Labels: mesosphere (was: )
> Initial support for GPU resources.
> ----------------------------------
>
> Key: MESOS-4424
> URL: https://issues.apache.org/jira/browse/MESOS-4424
> Project: Mesos
> Issue Type: Epic
> Components: isolation
> Reporter: Benjamin Mahler
> Assignee: Kevin Klues
> Labels: mesosphere
>
> Mesos already has generic mechanisms for expressing / isolating resources,
> and we'd like to expose GPUs as resources that can be consumed and isolated.
> However, GPUs present unique challenges:
> * Users may rely on vendor-specific libraries to interact with the device
> (e.g. CUDA, HSA, etc), others may rely on portable libraries like OpenCL or
> OpenGL. These libraries need to be available from within the container.
> * GPU hardware has many attributes that may impose scheduling constraints
> (e.g. core count, total memory, topology (via PCI-E, NVLINK, etc), driver
> versions, etc).
> * Obtaining utilization information requires vendor-specific approaches.
> * Isolated sharing of a GPU device requires vendor-specific approaches.
> As such, the focus is on supporting a narrow initial use case: homogenous
> device-level GPU support:
> * Fractional sharing of GPU devices across containers will not be supported
> initially, unlike CPU cores.
> * Heterogeneity will be supported via other means for now (e.g. using agent
> attributes to differentiate hardware profiles, using portable libraries like
> OpenCL, etc).
