rtStreamSynchronize (AICPU) fails with error 507018 in TensorMap and RingBuffer runtime

[Crystal-wzy]

Problem

Running the BGEMM example with TensorMap and RingBuffer runtime fails during AICPU stream synchronization.

Environment

• Platform: a2a3
• Runtime: tensormap_and_ringbuffer

Steps to Reproduce

python simpler/examples/scripts/run_example.py \
  -k simpler/examples/tensormap_and_ringbuffer/bgemm/kernels \
  -g simpler/examples/tensormap_and_ringbuffer/bgemm/golden.py \
  -p a2a3 \
  -d=7

Error Output

=== rtStreamSynchronize stream_aicpu_===
[ERROR] run: rtStreamSynchronize (AICPU) failed: 507018
[ERROR] TEST FAILED: launch_runtime failed: 507018

Expected Behavior

The BGEMM example should complete successfully and pass the golden test validation.
