cmake error when building with arbox

[Kaushik Das]

Hi,

If I turn on Arborx then cmake is also looking for ADOLC. 

Is Arborx support dependent on ADOLC?

I have attached a log from a docker build. Arborx was built first then I used -DDEAL_II_WITH_ARBORX=ON  and -DARBORX_DIR="/usr/local/Arborx" but cmake thorws an error  "ADOLC_INCLUDE_DIR not found!"

Thanks,

Kaushik

Kaushik,

The message you see is the auto-detect trying to find ADOLC. It's OK if the auto-detect does not find ADOLC. The real issue is with Kokkos. When you installed ArborX, did you use the Kokkos library from Trilinos or did you install Kokkos yourself too?

Best,

Bruno

Thanks for the clarification. I installed Kokkos separately, and I also have Trilinos support. Can this issue be related to Kokkos's version? It seems the latest Arborx needs Kokkos 4.3.00, but I have 4.3.01. It's not a major version mismatch, though.

The issue is that you have two versions of Kokkos installed. You can only have a single version of Kokkos. Remove the version of Kokkos you installed yourself and reinstall ArborX . Set the Kokkos directory to the Trilinos directory when configuring ArborX.

I see. The only reason I installed Kokkos separately was I wanted to use Kokkos GPU and LAMDA support for other parts of my code. But I could not find how to do that for kokkos that come with Trilinos. Specifically, I want to set these kokkos cmake configs -DKokkos_ENABLE_CUDA=ON, -DKokkos_ARCH_PASCAL61=ON,  -DKokkos_ENABLE_OPENMP=ON , -DCMAKE_CXX_COMPILER=/kokkos/bin/nvcc_wrapper,  -DKokkos_ENABLE_CUDA_LAMBDA=ON,  -DKokkos_ENABLE_CUDA_CONSTEXPR=ON, -DKokkos_ENABLE_AGGRESSIVE_VECTORIZATION=ON. For some reason, automatic detection of ARCH does not work on my machine so I have to set  Kokkos_ARCH_PASCAL61 explicitly. And I could not find a way to do that for the kokkos that comes with Trilinous. I would appreciate any help on this matter. Thank you.

Kaushik,

You can use the same flags you are using to configure the standalone
Kokkos to configure Kokkos inside Trilinos.

Best,
Daniel

Thanks for the tip. Using kokkos that came with trillions solved my problem.

Hello again, I may have declared victory a little too early. cmake configure completes but I am getting some build error. This may be due to version compatibility. Please let me know what versions of Trilinous, Kokkos (that comes with Trilinous), ArborX are compatible with dealii 9.4?

I am using dealii 9.6, trilinos-release-13-4-1, kokkos 3.6, ArborX v1.3. (Later versions of ArborX seem to need higher versions of Kokkos.) 

Just to let you know, the errors are as below: 

Thank you.
