we have to define some sort of physical representation for them. The most common representation is to lay out each element of the tensor contiguously in memory (that's where the term contiguous comes from), writing out each row to memory. ...
NCCL init hits CUDA failure 'invalid argument' on 12.2 driver Some users with 12.2 CUDA driver (535 version) report seeing "CUDA driver error: invalid argument" during NCCL or Symmetric Memory initialization. This issue is currently under investigation, see#150852. If you use PyTorch from source...
Causal Mask, and PrefixLM with just a few lines of idiomatic PyTorch code. This API leverages torch.compile to generate a fused FlashAttention kernel, which eliminates extra memory allocation and achieves performance comparable to handwritten implementations. Additionally, we automatically...
Linode GPU plans are available with a range of memory, storage, and GPUs. PyTorch Lightning can efficiently allocate the Nvidia RTX 6000’s Compute Unified Device Architecture (CUDA) cores. The CUDA cores are allocated (either specifically or automatically) to match the demands of training loops ...

Tensors and Dynamic neural networks in Python with strong GPU acceleration - Solid XPU UT test_memory_allocation (#141325) · pytorch/pytorch@1af69ee
Added correct handling for tensor allocation for large tensors when using torch.resize on CUDA (#52672). Fixed an illegal memory access that could happen when computing the inverse of a batch of matrices on CUDA (#53064). Fixed a bug where torch.sparse.addmm would compute the wrong results...
reserved是 Pytorch 进程管理的所有显存块,即torch.cuda.memory_reserved()的值 reserved=allocated+cached cuda context为每个使用 CUDA Runtime API 的进程必须创建的上下文,通常占用 500M ~ 1G 的显存,实际占用大小与 Cuda Driver 版本、Cuda 版本相关,官方知乎中有详细的介绍。
