Szilard Nemeth commented on YARN-9136:
--------------------------------------
Hi [~mhudaky]!
1. Comment to the part that describes response for FPGA devices:
{code}
The response to this request if there are FPGA device(s) present
{code}
Looking at this method:
org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin.fpga.FpgaResourcePlugin#getNMResourceInfo,
it seems in case of FpgaResourcePlugin, the response is empty so the response
won't have the list of NMDeviceResourceInfo objects serialized.
How did you come to the conclusion that these type of objects are being
serialized in case of FPGA devices are present?
I'm not sure in case of FPGa, the method
org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin.deviceframework.DevicePluginAdapter#getNMResourceInfo
or the same method of FpgaResourcePlugin will be invoked.
[~pbacsko] Can you help with this?
2. Nit: With 2 occurrences, you have:
{code}
AssignedDevice include container ID
{code}
include should be includes.
3. GPU devices can be manually configured, nvidia-smi is not a prerequisite
software to install to the system:
{code}
Contains all GPU Device Information in the system, fetched from nvidia-smi.
{code}
Please remove any reference to nvidia-smi.
