opencl sample makefile

Here is the skeleton of my Makefiles for opencl
It almost same as normal unix application Makefile
Add just opencl libs and opencl include directory
It is based on AMD Streaming SDK

TARGET := hellocl CPPOBJDIR = cppobjs CPPSOURCES := $(wildcard *.cpp) CPPOBJS := $(CPPSOURCES:%.cpp=$(CPPOBJDIR)/%.o) COBJDIR = cobjs CSOURCES := $(wildcard *.c) COBJS := $(CSOURCES:%.c=$(COBJDIR)/%.o) OBJS = $(CPPOBJS) $(COBJS) OPT_FLAGS := -fno-strict-aliasing -O2 INC := -I/opt/AMDAPP/include/ LIB := -L/usr/lib64/ LIB += -lOpenCL CXXFLAGS := -m64 -DUNIX $(WARN_FLAGS) $(OPT_FLAGS) $(INC) CFLAGS := -m64 -DUNIX $(WARN_FLAGS) $(OPT_FLAGS) $(INC) LDFLAGS := $(LIBRARY_PATH) $(LIB) .PHONY: clean $(TARGET): $(CPPOBJDIR) $(COBJDIR) $(CPPOBJS) $(COBJS) g++ -fPIC -o $(TARGET) $(CPPOBJS) $(LDFLAGS) $(CPPOBJS): $(CPPOBJDIR)/%.o: %.cpp @echo "compile $@ $<" g++ -fPIC $(CXXFLAGS) -c $< -o $@ $(COBJS): $(COBJDIR)/%.o: %.c @echo "compile $@ $<" gcc -fPIC $(CFLAGS) -c $< -o $@ $(CPPOBJDIR): @ mkdir -p $(CPPOBJDIR) $(COBJDIR): @ mkdir -p $(COBJDIR) clean: $(RM) $(TARGET) $(OBJ) $(RM) -rf $(CPPOBJDIR) $(RM) -rf $(COBJDIR)

Here is the result... I used helloworld sample of opencl programming guide

 

opencl programming guide sample cmake error

env:

ubuntu 10.04
AMD Straming SDK 2.6

CMake shows below error ,
because AMD Straming ASK OpenCl header directory is changed
...
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:70 (MESSAGE):
  Could NOT find OpenCL (missing: OPENCL_INCLUDE_DIRS)
...

Open

opencl-book-samples-read-only/cmake/FindOpenCL.cmake

add AMD straming SDK opencl include path as llike below

FIND_PATH(OPENCL_INCLUDE_DIRS CL/cl.h PATHS ${_OPENCL_INC_CAND} "/usr/local/cuda/include" "/opt/AMDAPP/include/")
            FIND_PATH(_OPENCL_CPP_INCLUDE_DIRS CL/cl.hpp PATHS ${_OPENCL_INC_CAND} "/usr/local/cuda/include" "/opt/AMDAPP/include/")

then cmake

$ cmake ../opencl-book-samples-read-only -G "Eclipse CDT4 - Unix Makefiles"
-- Found OpenCL: /usr/lib/libOpenCL.so

it is completed

move to chapters 2 sample directory and build , you can find out HelloWorld

env

windows 7
Nvidia CUDA 5.0


use cmake-gui

set source code directory and build binary directory , then configure and generate

Installing CUDA toolkit

env

OS : window 7
CUDA version : V5.0
Graphic Card : Geforce 9500 GT

- Cuda toolkit download
https://developer.nvidia.com/cuda-downloads

- Cuda sample download
http://docs.nvidia.com/cuda/cuda-samples/index.html

- Supported GPU list
https://developer.nvidia.com/cuda-gpus

Install only CUDA toolkit, it contains everything you need as you can see

























For verifing installation, open a sample and run

For example, in window7, go to
C:\ProgramData\NVIDIA Corporation\CUDA Samples\v5.0\1_Utilities\deviceQueryDrv
then open Visual Studio project , build and run

I used Visual Studio Express 10

You can download here.

Raspberry Pi - cat surveillance system

Install web cam server

I used Logitech C170

 

Install opencl with AMD streaming SDK

Installed env:

OS : unbuntu 10.04 , 64bits
Graphic Card : AMD Radeaon HD 4870
AMD Straming SDK 2.6

- AMD driver download

http://support.amd.com/us/gpudownload/linux/legacy/Pages/legacy-radeon_linux.aspx
http://support.amd.com/us/gpudownload/linux/previous/Pages/radeon_linux.aspx

- stream SDK download
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/

1. Check your Graphic card supports opencl or not
You can check here
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/system-requirements-driver-compatibility/

if the graphic card is not supported , download lower version and check

AMD-APP-SDK-<version>-RC-lnx64\docsAMD_APP_SDK_Getting_Started_Guide_<version>.pdf

2. install driver and opencl SDK
 unzip SDK package then run Install-AMD-APP.sh with root log-in

3. go to <install_dir>/AMD-APP-SDK-v2.x-RC3-lnx64/samples/opencl then make

 if you do not install openGL you get build error with below message

/opt/AMDAPP/include/GL/glew.h:1138:20: error: GL/glu.h: No such file or directory

in this case install openGL

$ sudo apt-get install freeglut3-dev

then make again, build will be succeeded

ubuntu svn server install ( over apache )

I installed svn server under ubuntu LTS 10.04 64 bits

SVN Server Setup

1. install essentail packages

#  sudo apt-get install subversion libapache2-svn apache2

2. create repository

 # svnadmin create /home3/swmgr/tmpsvn/sample

3. configure conf file

open  /home3/swmgr/tmpsvn/sample/conf/svnserve.conf

then uncommnet belows
 auth-access = write ==> set permission
 password-db = passwd ==> indicate passward file

open /home3/swmgr/tmpsvn/sample/conf/passwd

then add user and passward

[users]

user = passwd
dokyun = hellscream

4. start svn server
 svnserve -d -r /home3/swmgr/tmpsvn/sample

5. check
# svn checkout svn://192.168.0.4 ./svn
 or
# svn checkout svn://localhost ./svn

if  ,,, /db/txn-current-lock': Permission denied  error happens when svn access
check the directory permission.
$ chmod -R 775 /home3/swmgr/tmpsvn/sample

SVN over Apache

1. set directory owner
 # sudo chown -R www-data /home3/swmgr/tmpsvn/sample/

2. configure
 open /etc/apache2/mods-enabled/dav_svn.conf
 then add

<Location /svn>
  DAV svn
  SVNPath /home3/swmgr/tmpsvn/sample
  AuthType Basic
  AuthName "Subversion Repository"

  AuthUserFile /etc/apache2/dav_svn.passwd

  Require valid-user
</Location>

3. add user
# sudo htpasswd2 -cm /etc/apache2/dav_svn.passwd dokyun
 or
# sudo htpasswd -cm /etc/apache2/dav_svn.passwd dokyun

4. restart apache
 sudo /etc/init.d/apache2 restart
5. check

 refer to http://davidwinter.me/articles/2006/02/16/subversion-over-apache-2-on-ubuntu/

sulogin: no password entry for root

default console device is not set properly in inittab
Set tty device in inittab , for example

if console was set as

::respawn:/sbin/getty 115200 ttyO0

in inittab and you started with ttyO2,  then

sulogin: no password entry for root

message shows

set

::respawn:/sbin/getty 115200 ttyO2

you can log in properly
