torch.xpu.max_memory_reserved

torch.xpu.max_memory_reserved(device=None)

Return the maximum GPU memory managed by the caching allocator in bytes for a given device.

By default, this returns the peak cached memory since the beginning of this program. reset_peak_memory_stats() can be used to reset the starting point in tracking this metric. For example, these two functions can measure the peak cached memory amount of each iteration in a training loop.

Parameters

device (torch.device or int or str, optional) – selected device. Returns statistic for the current device, given by current_device(), if device is None (default).

Return type

int
