WSL2 Docker释放磁盘空间

Docker使用久了，会残留很多中间生成的镜像，占用磁盘空间。

要清理Docker镜像，本来是挺简单的，一条命令就搞定了：

gavinb

The following error message may be encountered when building CUDA code with CMake:

error LNK2019: unresolved external symbol __cudaRegisterLinkedBinary

It is caused by generated glue code not being linked in. The glue code is generated into files named with the project and a suffix:

myprojectname.device-link.obj

Ensure CUDA is enabled as a language for the project:

Multi-node-training on slurm with PyTorch

What's this?

• A simple note for how to start multi-node-training on slurm scheduler with PyTorch.
• Useful especially when scheduler is too busy that you cannot get multiple GPUs allocated, or you need more than 4 GPUs for a single job.
• Requirement: Have to use PyTorch DistributedDataParallel(DDP) for this purpose.
• Warning: might need to re-factor your own code.
• Warning: might be secretly condemned by your colleagues because using too many GPUs.
