Add GPU unit test

[weicongw]

Issue #, if available:

Description of changes:

• Add GPU unit tests. The tests contain following:

  • test_sysinfo.sh :: Validate basic system configuration by comparing it with config

    • test_numa_topo_topo :: check cpu/numa topology
    • test_nvidia_gpu_count :: fail if one of GPUs is broken or is not visiable
    • test_nvidia_fabric_status :: fail if fabric manager is not active
    • test_nvidia_smi_topo :: fail if nvidia-smi topology is differ
    • test_nvidia_persistence_status :: validate persistence state
    • test_nvidia_gpu_unused :: Check that no other process are using GPUs, fail is a signal system misconfiguration.

  • 10_test_basic_cuda.sh :: Execute trivial cuda binaries, fail if cuda subsys is not healthy Use demo-suite binaries https://docs.nvidia.com/cuda/demo-suite/index.html and DCGM Diagnostics https://docs.nvidia.com/datacenter/dcgm/latest/user-guide/dcgm-diagnostics.html#run-levels-and-tests If this test suite fail this is a sign that cuda subsystem is not usable at all. Usually this is side effect of system misconfiguration (driver or fabric manager is not loaded)

  • test_01_device_query

  • test_02_vector_add

  • test_03_bandwidth

  • test_04_bus_grind

  • test_05_dcgm_diagnostics

• Reuse the nccl test docker file for the unit tests

Test example:

Example of successful test execution:

ok - test_01_device_query
ok - test_02_vector_add
ok - test_03_bandwidth
ok - test_04_bus_grind
ok - test_05_dcgm_diagnostics
# Running tests in gpu_unit_tests/tests/test_sysinfo.sh
ok - test_numa_topo_topo
ok - test_nvidia_gpu_count
ok - test_nvidia_gpu_throttled
ok - test_nvidia_gpu_unused
ok - test_nvidia_persistence_status
ok - test_nvidia_smi_topo

Example of failed test execution (when the GPU count doesn't match our config data):

# Running tests in gpu_unit_tests/tests/test_basic.sh
ok - test_01_device_query
ok - test_02_vector_add
ok - test_03_bandwidth
ok - test_04_bus_grind
ok - test_05_dcgm_diagnostics
# Running tests in gpu_unit_tests/tests/test_sysinfo.sh

ok - test_numa_topo_topo
not ok - test_nvidia_gpu_count
