下面是记录的笔记,安装SDK后需要确认一些信息
- nvidia-smi -a 查看GPU状态命令
- /root/NVIDIA_CUDA-7.0_Samples/bin/x86_64/linux/release 这个下面有一系列的GPU的测试工具,可以使用
- 查看
- [root@localhost release]# ./deviceQuery
- ./deviceQuery Starting...
- CUDA Device Query (Runtime API) version (CUDART static linking)
- Detected 1 CUDA Capable device(s)
- Device 0: "Tesla K20c"

- Total number of registers available per block: 65536
- Warp size: 32
- Maximum number of threads per multiprocessor: 2048
- Maximum number of threads per block: 1024
- Max dimension size of a thread block (x,y,z): (1024, 1024, 64)
- Max dimension size of a grid size (x,y,z): (2147483647, 65535, 65535)
- Maximum memory pitch: 2147483647 bytes
- Texture alignment: 512 bytes
- Concurrent copy and kernel execution: Yes with 2 copy engine(s)
- Run time limit on kernels: No
- Integrated GPU sharing Host Memory: No
- Support host page-locked memory mapping: Yes
- Alignment requirement for Surfaces: Yes
- Device has ECC support: Enabled
- Device supports Unified Addressing (UVA): Yes
- Device PCI Domain ID / Bus ID / location ID: 0 / 4 / 0
- Compute Mode:
- < Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) >
- deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 7.0, CUDA Runtime Version = 7.0, NumDevs = 1, Device0 = Tesla K20c
- Result = PASS
