    Description

      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).
