I am new to multi-gpu training. My code ran perfectly on my Laptop's GPU (single RTX 3060) and it runs out of memory using four GPUs. I think it may be due to a misconfiguration of my GPUs or misuse of DDP strategy in Lightning. I hope someone can help me debug the log messages...

Run runai help submit for details on available flags. Here is a part of the available flags related to Resource Allocation in Run:AI: GPU-related flags: --gpu-memory <string>: GPU memory that will be allocated for this Job (e.g., 1G, 20M, etc). Attempting to allocate more GPU ...
Make sure that the modules you intend to debug are built with the compiler generating debug symbols. If a module has no symbols, then debugging is disabled for all functions in that module. Note: CPU/GPU Debugging Support The Legacy CUDA debugger only supports debugging GPU CUDA kernels. ...
