From f25e60ba1c7e68663117ab4863e8f25bf6df282c Mon Sep 17 00:00:00 2001 From: Prachi Gupta Date: Wed, 30 Jul 2025 16:26:55 -0400 Subject: [PATCH] [AUTOGENERATED] [release/2.7] [rocm7.0_internal_testing][SWDEV-541056][MI355] Fix distributed failures - Skip *_stress_cuda UTs for all archs - Symmetric Memory is not yet supported on rocm7.0_internal_testing branch - test_extra_cuda_context - add a barrier to ensure all nodes finish init_process_group before continuing with the test - test_sac_ilp: skip for all rocm arch (was already skipped for MI300 and NAVI) - test_fsdp2_mem_tracker: update tol - test_scaled_mm - this is row-wise scaling dependent, skipped for now - test_allreduce_inductor_cudagraph_trees: Skipped as flaky upstream as well - test_distributed_spawn - skipped, will be fixed in next IFU Also fixes: https://ontrack-internal.amd.com/browse/SWDEV-544875 --- test/distributed/_tools/test_fsdp2_mem_tracker.py | 4 ++-- test/distributed/_tools/test_sac_ilp.py | 5 ++--- test/distributed/tensor/test_matrix_ops.py | 3 ++- test/distributed/test_c10d_gloo.py | 2 -- test/distributed/test_c10d_nccl.py | 8 ++++++++ test/distributed/test_inductor_collectives.py | 1 + test/distributed/test_symmetric_memory.py | 2 ++ torch/testing/_internal/distributed/distributed_test.py | 7 +++++++ 8 files changed, 24 insertions(+), 8 deletions(-) diff --git a/test/distributed/_tools/test_fsdp2_mem_tracker.py b/test/distributed/_tools/test_fsdp2_mem_tracker.py index 31ae32330dd7e..83ff95ec8a250 100644 --- a/test/distributed/_tools/test_fsdp2_mem_tracker.py +++ b/test/distributed/_tools/test_fsdp2_mem_tracker.py @@ -166,7 +166,7 @@ def test_tracker_non_root_forward_backward(self): self.assertAlmostEqual( accuracy, 1.0, -
