The BackburnerManagerGroupCapability keyword
specifies whether the nodes in your rendering network are equipped
with GPU-accelerated graphics cards or not. Based on the value of
this keyword, the Visual Effects and Finishing application enables
or disables the submission of jobs that require a GPU (such as floating
point jobs) to the rendering network.
The
BackburnerManagerGroupCapability keyword uses the following syntax
BackburnerManagerGroupCapability <group_capability>
where <group_capability> can be software, gpu,
or hybrid depending on the hardware of the
nodes in the rendering network.
- If none of the nodes in your rendering
network are equipped with GPUs, set the value of the keyword to software.
The application does not send jobs that require a GPU to the rendering
network, but only jobs that can be rendered in software mode (using
OSMesa) by the render nodes.
- If ALL the nodes in your rendering network
are equipped with GPUs, set the value of the keyword to gpu.
The application sends all jobs to the GPU-equipped nodes, even if
some jobs do not specifically require a GPU render node. The GPU-equipped
render nodes will render jobs that require a GPU, as well as OSMesa
jobs.
NoteIf your rendering
network also contains render nodes without a GPU, but the BackburnerManagerGroupCapability keyword
is incorrectly set to gpu,
all jobs are sent only to GPU-equipped render nodes, and the nodes
without a GPU are never used.
- If your rendering network contains a
mix of nodes with GPUs and without GPUs, set the keyword to hybrid. The
application sends all jobs to the rendering network, and Backburner Manager
distributes each job to the appropriate type of render node. Jobs that
require a GPU are sent only to GPU-equipped render nodes, while jobs
that do not require a GPU are sent to any available render node
(GPU or non-GPU) to be rendered in software mode.
NoteSet the BackburnerManagerGroupCapability
keyword to gpu or hybrid only if you are sure that
at least one node in your rendering network is equipped with a GPU.
Attempting to submit a job that requires a GPU to a rendering network with
no GPU-equipped render node results in the job being stuck in the
rendering queue indefinitely.
