[1/N]Port 3 distributed/_tools test cases to Intel GPU #159543

libohao1201 · 2025-07-31T03:31:20Z

For #114850, we will port distributed tests to Intel GPU.

We could enable Intel GPU with following methods and try the best to keep the original code styles:

use "torch.accelerator.current_accelerator()" to determine the accelerator backend
enabled XPU for some test path
skip some test cases which Intel GPU does not support

As of commit 4995377 with merge base fc80f68 ():

FLAKY - The following job failed but was likely due to flakiness present on trunk:

xpu / linux-jammy-xpu-2025.1-py3.9 / test (default, 5, 6, linux.idc.xpu) (gh) (disabled by #160243 but the issue was closed recently and a rebase is needed to make it pass)

        debug = False
-        dev = torch.device(torch.cuda.current_device())
+        dev = torch.device(torch.accelerator.current_device_index())


torch.acceleartor does not apply to cpu.

But I think the cpu has been skipped by @skip_if_lt_x_gpu(2).

I introduce a few memory-related APIs under torch.accelerator in #152932
We could use torch.accelerator APIs instead of get_device_module once #152932 landed.

To add the ciflow label ciflow/xpu please first approve the workflows that are awaiting approval (scroll to the bottom of this page).

This helps ensure we don't trigger CI on this PR until it is actually authorized to do so. Please ping one of the reviewers if you do not have access to approve and run workflows.
