# --- Race detection HIP tests ---
# Uses a lightweight config (race_test_config.json) with 1 XCD and 4 CUs
# instead of the full MI350X topology (8 XCDs, 256 CUs). Each race test
# spawns a complete simulation engine, and with ctest -j the full config
# causes OOM kills at moderate parallelism (~15+ concurrent tests). The
# race detector only needs a few CUs to exercise cross-wave and
# cross-workgroup synchronization checking.
# The gfx950 race detector cases include CDNA-specific inline assembly
# sequences for LDS and waitcnt coverage. Keep that binary on gfx950 even when
# generic HIP smoke tests are overridden for local validation on another ISA.
