[gem5-users] gem5 + DGPU (GCN3) build error

[David Fong via gem5-users]

Hi,

I built gem5 + DGPU (GCN3) (gfx900) and ran DNNMark with this command-line

[gem5-resources]  docker run --rm -v ${PWD}:${PWD} 
-v${PWD}/cachefiles:/root/.cache/miopen/2.9.0 -w ${PWD} 
gcr.io/gem5-test/gcn-gpu:v21-2 python3 generate_cachefiles.py cachefiles.csv 
--gfx-version=gfx900 --num-cus=4

[gem5-gpu-dnn] 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 --dgpu --gfx-version=gfx900 -n3 
--benchmark-root=gem5/gem5-resources/src/gpu/DNNMark/build/benchmarks/test_fwd_softmax
 -cdnnmark_test_fwd_softmax --options="-config 
gem5/gem5-resources/src/gpu/DNNMark/config_example/softmax_config.dnnmark -mmap 
gem5/gem5-resources/src/gpu/DNNMark/mmap.bin"

and got this error message :

Exiting because  exiting with last active thread context

Am I missing a step in compilation process or some other settings ?

Thanks,

David
