> The NodeManager invokes an external binary (e.g. {{nvidia-smi}}) to discover attached GPUs. Right now, there is a hard-coded 10-second timeout on execution of this binary and a hard-coded max error count of 10, beyond which the NodeManager will stop attempting discovery. This change will provide new configuration properties to control both the timeout and the max errors, which is useful in environments where there may be a delay in binding the GPU to the host. Default values for the new configuration properties will be set so as to maintain the existing behavior.
