(轉)Basic configuration of CUDA

轉載自http://soft.zdnet.com.cn/software_zone/2009/1127/1527418.shtml

 

1、軟件需求:

      cudadriver_2.3_winvista_64_190.38_general

  cudatoolkit_2.3_win_64

  cudasdk_2.3_win_64

  VS2008

  安裝前將之前安裝的sdk、toolkit、driver等卸載,再依次安裝上述軟件。如果開發平臺沒有支持CUDA的顯卡,則不需要安裝cudadriver_2.3_winvista_64_190.38_general。

  2、 安裝檢查

  在cmd下執行nvcc –V可以查看當前版本號

  nvcc: NVIDIA (R) Cuda compiler driver

  Copyright (c) 2005-2009 NVIDIA Corporation

  Built on Mon_Aug__3_19:43:55_PDT_2009

  Cuda compilation tools, release 2.3, V0.2.1221

  執行bandwidthtest查看配置是否正常

  進入ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCbinwin64Release>目錄,執行

  .bandwidthTest.exe --memory=pinned --mode=range --start=10240000 --end=10240000 -increment=10240000

  若正常會有類似信息

  Running on......

  device 0:Quadro FX 580

  Range Mode

  Host to Device Bandwidth for Pinned memory

  Transfer Size (Bytes) Bandwidth(MB/s)

  10240000 5101.1

  Range Mode

  Device to Host Bandwidth for Pinned memory

  Transfer Size (Bytes) Bandwidth(MB/s)

  10240000 4650.8

  Range Mode

  Device to Device Bandwidth

  Transfer Size (Bytes) Bandwidth(MB/s)

  10240000 14812.5

  &&&& Test PASSED

  Press ENTER to exit...

  執行deviceQuery.exe查看顯卡具體型號

  . deviceQuery.exe

  若正常會有類似信息

  CUDA Device Query (Runtime API) version (CUDART static linking)

  There is 1 device supporting CUDA

  Device 0: "Quadro FX 580"

  CUDA Driver Version: 2.30

  CUDA Runtime Version: 2.30

  CUDA Capability Major revision number: 1

  CUDA Capability Minor revision number: 1

  Total amount of global memory: 536870912 bytes

  Number of multiprocessors: 4

  Number of cores: 32

  Total amount of constant memory: 65536 bytes

  Total amount of shared memory per block: 16384 bytes

  Total number of registers available per block: 8192

  Warp size: 32

  Maximum number of threads per block: 512

  Maximum sizes of each dimension of a block: 512 x 512 x 64

  Maximum sizes of each dimension of a grid: 65535 x 65535 x 1

  Maximum memory pitch: 262144 bytes

  Texture alignment: 256 bytes

  Clock rate: 1.13 GHz

  Concurrent copy and execution: Yes

  Run time limit on kernels: No

  Integrated: No

  Support host page-locked memory mapping: No

  Compute mode: Default (multiple host threads can use this device simultaneously)

  Test PASSED

  Press ENTER to exit...

  根據信息可以推算顯卡的單精度浮點處理性能爲3*32*1.13=108.48Gflops

  3、 設置系統環境變量

  將安裝的CUDA的sdk的路徑加到系統環境變量中:

  例如C:ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCbinwin64

  下的

  ├─Debug

  ├─EmuDebug

  └─EmuRelease

      └─Release

     

  幾個目錄都加入到系統環境變量PATH中,這樣才能在運行程序的時候找到相應的dll庫。(做法:添加%CUDARelease%到path中,CUDARelease爲設置的系統變量名稱)

 

  將編譯需要的頭文件放到vs2008環境中

  複製C:ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCcommon目錄到C:UsersdawningDocumentsVisual Studio 2008下

 

  4、 VS2008建立CUDA簡單的工程

  將模板項目C:ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCsrc template拷貝到vs2008項目目錄C:UsersdawningDocumentsVisual Studio 2008Projects

  打開vs2008,打開模板項目template_vc90
