Verify CUDA InstallationΒΆ
The following verification steps only apply to the ``cudafull`` installations.
Verify driver version by looking at:
/proc/driver/nvidia/version
:# cat /proc/driver/nvidia/version NVRM version: NVIDIA UNIX ppc64le Kernel Module 352.39 Fri Aug 14 17:10:41 PDT 2015 GCC version: gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC)
Verify the CUDA Toolkit version
# nvcc -V nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2015 NVIDIA Corporation Built on Tue_Aug_11_14:31:50_CDT_2015 Cuda compilation tools, release 7.5, V7.5.17
Verify running CUDA GPU jobs by compiling the samples and executing the
deviceQuery
orbandwidthTest
programs.Compile the samples:
[RHEL]:
cd ~/ cuda-install-samples-7.5.sh . cd NVIDIA_CUDA-7.5_Samples make
[Ubuntu]:
cd ~/ apt-get install cuda-samples-7-0 -y cd /usr/local/cuda-7.0/samples make
Run the
deviceQuery
sample:# ./bin/ppc64le/linux/release/deviceQuery ./deviceQuery Starting... CUDA Device Query (Runtime API) version (CUDART static linking) Detected 4 CUDA Capable device(s) Device 0: "Tesla K80" CUDA Driver Version / Runtime Version 7.5 / 7.5 CUDA Capability Major/Minor version number: 3.7 Total amount of global memory: 11520 MBytes (12079136768 bytes) (13) Multiprocessors, (192) CUDA Cores/MP: 2496 CUDA Cores GPU Max Clock rate: 824 MHz (0.82 GHz) Memory Clock rate: 2505 Mhz Memory Bus Width: 384-bit L2 Cache Size: 1572864 bytes ............ deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 7.5, CUDA Runtime Version = 7.5, NumDevs = 4, Device0 = Tesla K80, Device1 = Tesla K80, Device2 = Tesla K80, Device3 = Tesla K80 Result = PASS
Run the
bandwidthTest
sample:# ./bin/ppc64le/linux/release/bandwidthTest [CUDA Bandwidth Test] - Starting... Running on... Device 0: Tesla K80 Quick Mode Host to Device Bandwidth, 1 Device(s) PINNED Memory Transfers Transfer Size (Bytes) Bandwidth(MB/s) 33554432 7765.1 Device to Host Bandwidth, 1 Device(s) PINNED Memory Transfers Transfer Size (Bytes) Bandwidth(MB/s) 33554432 7759.6 Device to Device Bandwidth, 1 Device(s) PINNED Memory Transfers Transfer Size (Bytes) Bandwidth(MB/s) 33554432 141485.3 Result = PASS
