Your cluster or multi-node appliance might contain nodes with different resources and different capacity. Therefore, each node can be configured separately.
Show node configuration
To display the current node configuration for a node (for example, lxd0), enter the following command:
amc node show <node>
This command will return output similar to the following:
name: lxd0
status: online
disk:
size: 100GB
network:
address: 10.119.216.34
bridge-mtu: 1500
config:
public-address: 10.119.216.34
use-port-forwarding: true
cpu-cores: 8
cpu-allocation-rate: 4
memory: 16GB
memory-allocation-rate: 2
gpu-slots: 10
gpu-encoder-slots: 0

Configure allocation rates
AMS allows over-committing available resources on a node. This mechanism improves resource usage, because usually, containers don’t use 100% of their dedicated resources all of the time.
By default, AMS uses a CPU allocation rate of 4 and a memory allocation rate of 2. See Over-committing for more information.
You can configure the allocation rates with the cpu-allocation-rate and memory-allocation-rate configuration items.
Use the following commands to set the allocation rates on a node (for example, lxd0):
amc node set <node> cpu-allocation-rate <value>
amc node set <node> memory-allocation-rate <value>
Configure GPU slots
GPU slots are used to share GPUs amongst containers. See About GPU support and GPU slots for more information.
Each GPU-equipped cluster node is configured with a number of GPU slots and a number of GPU encoder slots. See Node-specific configuration for the default values that are used. Nodes without GPU are configured with 0 GPU slots and 0 GPU encoder slots.
Use the following command to change the number of GPU slots for a node (for example, lxd0):
amc node set <node> gpu-slots <number>
