but if there is a place in the code where the main max_memory_allocated counter is updated won't this require a relatively simple change where instead of updating a single counter, it will update as many counters as there are registered to be updated? And...

max_split_size_mb是PyTorch中用于CUDA内存管理的一个环境变量参数。它设置了CUDA内存块可被分割的最大尺寸(以MB为单位)。这个参数的主要目的是减少内存碎片,从而避免在内存充足的情况下因无法找到连续的空闲内存块而导致的“CUDA out of memory”错误。 2. 查找如何设置max_split_size_mb参数 max_split_size_mb...
Based on BIOS debug log, BIOS successfully changed the memory ceiling value but when I boot into Linux and check the memory allocation with iomem, it is reverted back to 2G. The main reason I would like to reduce maximum TOLUD is to increa...
importtorch torch.backends.cuda.max_split_size_mb=1024# 设置每个块的最大尺寸为1GB 如果使用多GPU训练时,可以尝试将数据并行度调小,即减少每个GPU上的batch size。 如果以上方法都没有解决问题,则需要考虑使用更高配置的GPU或者增加机器内存来缓解该问题。
1.If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF 这里要注意是你的reserved memory is >>allocated memory可以使用的,但也不是一定有用,最后最后如果还不行的话可以试试(参数128可以调整...
