From b50bc2c1d4375b22082caf41a744c53be5befb82 Mon Sep 17 00:00:00 2001 From: Philip Hyunsu Cho Date: Sat, 29 Sep 2018 11:20:58 -0700 Subject: [PATCH] Add multi-GPU unit test environment (#3741) * Add multi-GPU unit test environment * Better assertion message * Temporarily disable failing test * Distinguish between multi-GPU and single-GPU CPP tests * Consolidate Python tests. Use attributes to distinguish multi-GPU Python tests from single-CPU counterparts --- Jenkinsfile | 6 ++++-- tests/ci_build/jenkins_tools.Groovy | 4 ++-- tests/ci_build/test_gpu.sh | 4 ++-- tests/ci_build/test_mgpu.sh | 8 ++++++++ tests/cpp/tree/test_gpu_hist.cu | 11 +++++++++++ tests/python-gpu/test_gpu_updaters.py | 16 +++++++++++++++- 6 files changed, 42 insertions(+), 7 deletions(-) create mode 100755 tests/ci_build/test_mgpu.sh diff --git a/Jenkinsfile b/Jenkinsfile index f590e1b0b..cc9f12cfa 100644 --- a/Jenkinsfile +++ b/Jenkinsfile @@ -14,6 +14,7 @@ def dockerRun = 'tests/ci_build/ci_build.sh' def utils def buildMatrix = [ + [ "enabled": true, "os" : "linux", "withGpu": true, "withNccl": true, "withOmp": true, "pythonVersion": "2.7", "cudaVersion": "9.2", "multiGpu": true], [ "enabled": true, "os" : "linux", "withGpu": true, "withNccl": true, "withOmp": true, "pythonVersion": "2.7", "cudaVersion": "9.2" ], [ "enabled": true, "os" : "linux", "withGpu": true, "withNccl": true, "withOmp": true, "pythonVersion": "2.7", "cudaVersion": "8.0" ], [ "enabled": true, "os" : "linux", "withGpu": true, "withNccl": false, "withOmp": true, "pythonVersion": "2.7", "cudaVersion": "8.0" ], @@ -67,9 +68,10 @@ def buildPlatformCmake(buildName, conf, nodeReq, dockerTarget) { // Destination dir for artifacts def distDir = "dist/${buildName}" def dockerArgs = "" - if(conf["withGpu"]){ + if (conf["withGpu"]) { dockerArgs = "--build-arg CUDA_VERSION=" + conf["cudaVersion"] } + def test_suite = conf["withGpu"] ?
