Building problem with GPU

Garfield++
1

I’m trying to build Garfield (master blanch) with GPU in my PC(AlmaLinux10.2). My PC has already installed ROOT v6.36.04 and v6.40.00 . When I build Garfield, the below message showed and can’t build it.

$cmake -Dcuda=ON ..

Check for working CUDA compiler: /usr/local/cuda/bin/nvcc - skipped
– Detecting CUDA compile features
– Detecting CUDA compile features - done

$make

Loading from the following files: …/AvalancheMicroscopicGPU.cu:19:
../garfieldpp-master/Include/Garfield/RandomEngineRoot.hh:

4:10: Fatal error: TRandom3.h: No such file or directory
4 | #include <TRandom3.h>

Trandom3.h is only included in Garfield/RandomEngineRoot.hh.

I can build Garfield without GPU.

Could you help to build Garfield with GPU?

Hi,
thanks a lot for your message! Could you try adding a line

target_include_directories(GarfieldGPU PRIVATE ${ROOT_INCLUDE_DIRS})

in CMakeLists.txt just before

target_compile_definitions(GarfieldGPU PRIVATE USEGPU)
endif()

Let me know if this works!

Thank you for your answers.

I add a below line in CMakeLists.txt

target_include_directories(GarfieldGPU PRIVATE ${ROOT_INCLUDE_DIRS})

just before

target_compile_definitions(Garfield PRIVATE BOOL:${GARFIELD_WITH_CUDA}:USEGPU>)

After then, I can build Garfield++ without errors (although there are many warnings).

I haven’t tested yet whether the program works correctly.

But I can’t find below lines

target_compile_definitions(GarfieldGPU PRIVATE USEGPU)
endif()

I can find

if(GARFIELD_CUDA_USE_FLOAT)
target_compile_definitions(Garfield PRIVATE GARFIELD_CUDA_USE_FLOAT)
endif()

Thank you very much!

Hi,

When the command

target_include_directories(GarfieldGPU PRIVATE ${ROOT_INCLUDE_DIRS})

is put on just before

target_include_directories(GarfieldGPU PRIVATE ${ROOT_INCLUDE_DIRS})

I can’t build garfield without GARFIELD_WITH_CUDA option

I modified to the below commands

if(GARFIELD_WITH_CUDA)
target_include_directories(GarfieldGPU PRIVATE ${ROOT_INCLUDE_DIRS})
endif()

Then I can build Garfield with and without GARFIELD_WITH_CUDA option.

However, I haven’t tested yet whether the program works correctly.

Thank you.

Hi, Heinrich Schindler,

I misunderstood your suggestion. Your suggestion is the line

target_include_directories(GarfieldGPU PRIVATE ${ROOT_INCLUDE_DIRS})

put in GPU/CMakeLists.txt. But I put this line in CMakeLists.txt on top directory.

Since you already modified GPU/CMakeLists.txt on master Branch, I tried to

build to the master Branch with GARFILED_WITH_CUDA option. But I can’t

build it because of same error message in below,

Loading from the following files: …/AvalancheMicroscopicGPU.cu:19:
../garfieldpp-master/Include/Garfield/RandomEngineRoot.hh:

4:10: Fatal error: TRandom3.h: No such file or directory
4 | #include <TRandom3.h>

Could you help to solve this problem?
