Build Failed on Ubuntu20.04 about altis HOT 4 OPEN

from altis.

@alice890308 if you set VERBOSE=1 before cmake command what does it show? This way we can see the exact build command and what files make is expecting. Is it possible to get the complete make log? My speculation is some files are not built due to unspecified SM numbers.

@BDHU Hi! It shows the following messages.

root@23cf7bea18ba:/altis/config/cuda_device_attr_gen# make VERBOSE=1
/usr/local/cuda/bin/nvcc -ccbin g++ -I../../Common  -m64    -gencode arch=compute_80,code=sm_80 -gencode arch=compute_80,code=compute_80 -o deviceQuery.o -c deviceQuery.cpp
/usr/local/cuda/bin/nvcc -ccbin g++   -m64      -gencode arch=compute_80,code=sm_80 -gencode arch=compute_80,code=compute_80 -o deviceQuery deviceQuery.o
mkdir -p ../../bin/x86_64/linux/release
cp deviceQuery ../../bin/x86_64/linux/release

Is this the complete make log you are looking for? Or would you like me to check anything else?

@alice890308 Apologies for the late reply. Can you go into the build directory and remove everything inside? Then execute these two commands:

cmake -DCMAKE_CUDA_ARCHITECTURES=$($SCRIPTPATH/config/get_cuda_sm.sh) ..

and

make VERBOSE=1

I've tested your setup with the exact same docker version and encountered no problem. However, I've only tested on SM61. Therefore, I suspect something has changed in the SM80 series. The above command allows us to see which specific make command causes the failure.

For example, I noticed you failed to build the maxflops object file. This is the first workload to build right after libAltisCommon.a is generated. In my setup, the building command is (that's why we need make VERBOSE=1 to show the message):

[  5%] Building CUDA object src/cuda/level0/maxflops/CMakeFiles/maxflopsLib.dir/MaxFlops.cu.o
cd /workspace/Desktop/altis/build/src/cuda/level0/maxflops && /usr/local/cuda/bin/nvcc   -I/workspace/Desktop/altis/src/cuda/common -I/workspace/Desktop/altis/src/cuda/../common  -w -gencode arch=compute_61,code=sm_61 -x cu -c /workspace/Desktop/altis/src/cuda/level0/maxflops/MaxFlops.cu -o CMakeFiles/maxflopsLib.dir/MaxFlops.cu.o

This specific line:

cd /workspace/Desktop/altis/build/src/cuda/level0/maxflops && /usr/local/cuda/bin/nvcc -I/workspace/Desktop/altis/src/cuda/common -I/workspace/Desktop/altis/src/cuda/../common -w -gencode arch=compute_61,code=sm_61 -x cu -c /workspace/Desktop/altis/src/cuda/level0/maxflops/MaxFlops.cu -o CMakeFiles/maxflopsLib.dir/MaxFlops.cu.o

is in charge of generating the MaxFlops.cu.o file. You can simple copy and rerun it to produce the same error without going through all the cmake generation process.

So in your setup, it might look like this:

[  5%] Building CUDA object src/cuda/level0/maxflops/CMakeFiles/maxflopsLib.dir/MaxFlops.cu.o
cd /workspace/Desktop/altis/build/src/cuda/level0/maxflops && /usr/local/cuda/bin/nvcc   -I/workspace/Desktop/altis/src/cuda/common -I/workspace/Desktop/altis/src/cuda/../common  -w -gencode arch=compute_80,code=sm_80 -x cu -c /workspace/Desktop/altis/src/cuda/level0/maxflops/MaxFlops.cu -o CMakeFiles/maxflopsLib.dir/MaxFlops.cu.o

I would first watch for any missing flags or parameters. It's very likely CMake failed to generate some commands.
