Build kokkos

[YuxinxinChen]

Hi,

I am trying to use graph coloring (GPU) in kokkos. However, I have a problem config the cmake.

mkdir build & cd build
cmake .. -DCMAKE_CXX_COMPILER=g++ -DKokkos_ROOT=/home/yuxin420/kokkos/kokkos/build -DCMAKE_INSTALL_PREFIX=/home/yuxin420/kokkos/kokkos-kernels/build -DKokkosKernels_REQUIRE_DEVICES=CUDA

But I got an error:

CMake Error at /home/yuxin420/kokkos/kokkos/build/KokkosConfig.cmake:62 (INCLUDE):
  INCLUDE could not find load file:

    /home/yuxin420/kokkos/kokkos/build/KokkosTargets.cmake
Call Stack (most recent call first):
  CMakeLists.txt:88 (FIND_PACKAGE)

Could you give more information on how to build Kokkos-kernel? Thanks

Yuxin

Hi Yuxin,
Make sure you have run "make install" for your Kokks build. Then the -DKokkos_ROOT value should point to the Kokkos install location, probably "-DKokkos_ROOT=/home/yuxin420/kokkos/kokkos/install".

Does that fix the problem?

Hi,

Thanks for your reply! I realized Kokkos is different from Kokkos kernel. I have installed kokkos and kokkos-kernel successfully.
I would like to run the GPU graph coloring and I noticed there is one under the perf_test directory. However, after make install kokkos-kernel, the tests under perf_test directory are not compiled and the CMakeList.txt under perf_test can not be run directly.
I would like to know how can I compile the perf_test code and run it. Could you help me with that?
Thanks very much!

Hi Yuxin,

It looks like you need to add KokkosKernels_ENABLE_TESTS:BOOL=ON when configuring kokkos-kernels. You can review the cmake options at https://github.com/kokkos/kokkos-kernels/blob/develop/BUILD.md#kokkos-kernels-cmake-option-listing.

@YuxinxinChen based on issue #1056 it seems that you are now able to compile Kokkos Kernels correctly.
I will close this issue and leave the other one open so you get answers on how to enable tests in one place.
