installation question #24

Closed zjin-lcf closed 2 years ago

zjin-lcf commented 2 years ago

Could you please show the instructions to install clacc from source ? Thanks.

jdenny-ornl commented 2 years ago

Hi,

You can find instructions in the top-level README.md, which is rendered here:

https://github.com/llvm-doe-org/llvm-project/tree/clacc/main

Let me know if you have any questions.

Thanks.

zjin-lcf commented 2 years ago

Is the common command build clacc targeting an nvidia gpu offloading below:

cmake -DCMAKE_INSTALL_PREFIX=../install -DLLVM_ENABLE_PROJECTS='clang' - DLLVM_ENABLE_RUNTIMES='openmp' -DCLANG_ACC_TEST_EXE_NVPTX64=6 -DCMAKE_BUILD_TYPE=Release ../llvm ?

jdenny-ornl commented 2 years ago

It's a good starting point if you indeed have 6 NVIDIA GPUs on your system.

Other cmake options might be required depending on your system. LLVM's documentation covers those. I'm happy to help if you're struggling to find the right combination for your system.

zjin-lcf commented 2 years ago

I got the following errors:

cmake -DCMAKE_INSTALL_PREFIX=../install -DLLVM_ENABLE_PROJECTS='clang' -DLLVM_ENABLE_RUNTIMES='openmp' \ -DCLANG_ACC_TEST_EXE_NVPTX64=4 -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD=NVPTX ../llvm

Then, I type "make"

jdenny-ornl commented 2 years ago

Please try either not setting LLVM_TARGETS_TO_BUILD or setting it as:

-DLLVM_TARGETS_TO_BUILD='host;NVPTX'

Are you working on an ExCL system? If so, let me know which one, and I can probably just paste a cmake config for you.

zjin-lcf commented 2 years ago

it is equinox.

The error message after setting the two targets is:

CMake Error at /usr/local/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find Threads (missing: Threads_FOUND)

Could these errors be detected before the status of 'make' reaches 100% ?

Thanks

jdenny-ornl commented 2 years ago

The following works for me on equinox:

$ module load nvhpc
$ PATH=/opt/nvidia/hpc_sdk/Linux_x86_64/21.7/cuda/11.4/bin:$PATH
$ cmake -DCMAKE_INSTALL_PREFIX=../install \
  -DLLVM_ENABLE_PROJECTS='clang' -DLLVM_ENABLE_RUNTIMES='openmp' \
  -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ \
  -DCLANG_ACC_TEST_EXE_NVPTX64=4 -DCMAKE_BUILD_TYPE=Release \
  ../llvm
zjin-lcf commented 2 years ago

It works for me. Thanks
