cuda-samples를 gpgpu-sim으로 빌드하기 - 절망편

cp -a /cuda-samples/Samples/0_Introduction/matrixMul/matrixMul .

cp -a /gpgpu-sim_distribution/configs/tested-cfgs/SM2_GTX480/gpgpusim.config .

 ./matrixMul 

[Matrix Multiply Using CUDA] - Starting...

CUDA error at ../../../Common/helper_cuda.h:796 code=100(cudaErrorNoDevice)
"cudaGetDeviceCount(&device_count)" 

1) cuda driver 설치 

2) gpgpu-sim에서 source setup_environmet make

 

 

그렇게 해서 실행 했을 때는 또 다른 에러가 났다.

symbol lookup error 는 뭔지

matrixMul에 필요한 라이브러리가 뭔지 확인해 봤다.

ldd matrixMul

잘 모르겠다~!
