Multi-Node (DeepSeek V3.2)

:::{note} Only machines with AArch64 are supported currently. x86 will be supported soon. This guide takes A3 as the example. :::

Verify Multi-Node Communication Environment

Physical Layer Requirements:

The physical machines must be located on the same WLAN, with network connectivity.
All NPUs are connected with optical modules, and the connection status must be normal.

Verification Process:

Execute the following commands on each node in sequence. The results must all be success and the status must be UP:

:::::{tab-set} ::::{tab-item} A2 series

 # Check the remote switch ports
 for i in {0..7}; do hccn_tool -i $i -lldp -g | grep Ifname; done 
 # Get the link status of the Ethernet ports (UP or DOWN)
 for i in {0..7}; do hccn_tool -i $i -link -g ; done
 # Check the network health status
 for i in {0..7}; do hccn_tool -i $i -net_health -g ; done
 # View the network detected IP configuration
 for i in {0..7}; do hccn_tool -i $i -netdetect -g ; done
 # View gateway configuration
 for i in {0..7}; do hccn_tool -i $i -gateway -g ; done
 # View NPU network configuration
 cat /etc/hccn.conf

:::: ::::{tab-item} A3 series

 # Check the remote switch ports
 for i in {0..15}; do hccn_tool -i $i -lldp -g | grep Ifname; done 
 # Get the link status of the Ethernet ports (UP or DOWN)
 for i in {0..15}; do hccn_tool -i $i -link -g ; done
 # Check the network health status
 for i in {0..15}; do hccn_tool -i $i -net_health -g ; done
 # View the network detected IP configuration
 for i in {0..15}; do hccn_tool -i $i -netdetect -g ; done
 # View gateway configuration
 for i in {0..15}; do hccn_tool -i $i -gateway -g ; done
 # View NPU network configuration
 cat /etc/hccn.conf

:::: :::::

NPU Interconnect Verification:

1. Get NPU IP Addresses

:::::{tab-set} ::::{tab-item} A2 series

for i in {0..7}; do hccn_tool -i $i -ip -g | grep ipaddr; done

:::: ::::{tab-item} A3 series

for i in {0..15}; do hccn_tool -i $i -ip -g | grep ipaddr; done

:::: :::::

2. Cross-Node PING Test

# Execute on the target node (replace with actual IP)
hccn_tool -i 0 -ping -g address 10.20.0.20

Deploy DeepSeek-V3.2-Exp with vLLM-Ascend

Currently, we provide a all-in-one image (include CANN 8.2RC1 + SparseFlashAttention/LightningIndexer + MLAPO). You can also build your own image by referring to link.

DeepSeek-V3.2-Exp: require 2 Atlas 800 A3 (64G × 16) nodes or 4 Atlas 800 A2 (64G × 8). Model weight link
DeepSeek-V3.2-Exp-w8a8: require 1 Atlas 800 A3 (64G × 16) node or 2 Atlas 800 A2 (64G × 8). Model weight link

Run the following command to start the container in each node (You should download the weight to /root/.cache in advance):
