Building with ROCm/HIP fails on a system without GPU #969
Comments
@lahwaacz thank you for the bug report, we will look into this. The UCC CI checker runs through exactly the same scenario (i.e. compiling UCC with the ROCm stack installed but without an AMD GPU being available). However, because of an issue that we faced with clang-tidy newer than clang-12, we fixed the ROCm version in the UCC CI to ROCm 5.7.1 - which still uses For now, I think your best options are either to compile on a platform with an AMD GPU present, or change the |
@edgargabriel Thanks, I've patched it for the Arch Linux package: https://gitlab.archlinux.org/archlinux/packaging/packages/openucc/-/commit/f5618b46d08fa2c41f218366871d17133145cde9#9b9baac1eb9b72790eef5540a1685306fc43fd6c_50_42 |
Hi @edgargabriel ! We also encountered the same issue ( It would be nice that we can provide the list of architectures that we want to compile for at the configuration step. For now, there are many Note that we circumvented the problem by patching |
@romintomasetti thank you, it is on our list, we definitely plan to have it fixed for the next release. I think the fix is not entirely trivial since cuda_lt.sh is used by both cuda and rocm component, so it might require a deeper rework of that part of the code section. |
Also, please note that there is already the option Lines 109 to 118 in 1522ccf

The
cuda_lt.sh
script contains a--offload-arch=native
flag for amdclang:ucc/cuda_lt.sh

This should select the native architecture of the GPU present in the build system. However, if the build system does not have any GPU, the command fails:
