Hi David,
My guess is you are using gfx801 for this? If so, does the application
actually error out at this point, or just proceed beyond it? If it's the
latter, my guess is MIOpen is just complaining that you're running with an APU,
which is less well optimized for. If it's the former, then there may be
something else in your setup we need to check.

Subject: [gem5-users] Error when running test_bwd_bn test
Hi,
When I run the DNNMark test_bwd_bn,
docker run --rm -v ${PWD}:${PWD} -v
${PWD}/gem5/gem5-resources/src/gpu/DNNMark/cachefiles:/root/.cache/miopen/2.9.0
-w ${PWD} gcr.io/gem5-test/gcn-gpu:v21-2 gem5/build/GCN3_X86/gem5.opt
gem5/configs/example/apu_se.py --num-compute-units 128 -n3 --gpu-to-dir-latency
120 --TCC_latency 16
--benchmark-root=gem5/gem5-resources/src/gpu/DNNMark/build/benchmarks/test_bwd_bn
-c dnnmark_test_bwd_bn --options="-config
gem5/gem5-resources/src/gpu/DNNMark/config_example/bn_config.dnnmark -mmap
gem5/gem5-resources/src/gpu/DNNMark/mmap.bin"
I get this error:
MIOpen(HIP): Error [ValidateGcnAssemblerImpl] Specified assembler does not
support AMDGPU. Expect performance degradation.
Does this mean the test will not run properly with AMD GPU and I should ignore
this test?
Or the AMD CPU will be doing the computations and it means the test will take
longer to complete?
David
