- How does one set the pytorch distributed hostname, port and . . .
Just resolved it, by adding an environment configuration: GLOO_SOCKET_IFNAME=eth0 How does one solve the: [W ProcessGroupGloo cpp:558] Warning: Unable to resolve hostname to a (local) address Using the loopback address as fallback Manually set the network interface to bind to with GLOO_SOCKET_IFNAM hellip;
- Distributed communication package - torch. distributed
If you’re using the Gloo backend, you can specify multiple interfaces by separating them by a comma, like this: export GLOO_SOCKET_IFNAME=eth0,eth1,eth2,eth3 The backend will dispatch operations in a round-robin fashion across these interfaces

NCCL and Gloo will try to find the right network interface to use If it is not the correct one, you can specify it by setting the environment variable NCCL_SOCKET_IFNAME or GLOO_SOCKET_IFNAME, depending on the backend you are using
- Why does pytorch gloo still send traffic from other TCP ports . . .
os environ['GLOO_SOCKET_IFNAME']=f'eth{args local_rank % 8}' dist init_process_group(backend='gloo', init_method='env: ') every local rank I tried specifiy LOO_SOCKET_IFNAME = eth {rank}, it doesn't work, there is still half workers choose eth0
- Tensorpipe requires setting both GLOO_SOCKET_IFNAME . . . - GitHub
On the FAIR cluster, nslookup $(hostname) reports 127 0 1 1 on every host, and this confuses gloo tensorpipe, requiring me to pass GLOO_SOCKET_IFNAME and TP_SOCKET_IFNAME in the environment for each worker, with the value set to the right interface for each worker
- Distributed Communication - FedLab 1. 3. 0 documentation
If the automatically detected interface does not work, users are required to assign a right network interface for Gloo, by assigning in code or setting the environment variables GLOO_SOCKET_IFNAME, for example export GLOO_SOCKET_IFNAME=eth0 or os environ['GLOO_SOCKET_IFNAME'] = "eth0"

If you are using gloo as your DDP communication backend, please set the correct network interface such as export GLOO_SOCKET_IFNAME=eth0 We provide examples with gloo and nccl as backend
