Building from source with multi-node multi-gpu support: CMake succeeds in writing build files but make command fails

sanjaysekaran · July 29, 2021, 9:01am

I am trying to build xgboost on a HPC cluster with multi-node multi-gpu support (as per the instructions here: https://xgboost.readthedocs.io/en/latest/build.html#obtaining-the-source-code). I am using gcc version 5.1.0, cmake version 3.14.4, cuda version 10.1 and nccl version 2.8.3-1, which the Nvidia website mentions is compatible with cuda version 10.1. Using the following cmake command: cmake .. -DUSE_CUDA=ON -DUSE_NCCL=ON -DNCCL_ROOT=/home/users/industry/silverfactorytechnology/sanjay.s/nccl/nccl_2.8.3-1+cuda10.1_x86_64, I get the following output:

I am not sure what I’m doing wrong, but repeating the above with cmake … -DUSE_CUDA=ON does not work either. Any help would be greatly appreciated.
