----------------------- Compiler ----------------------------
|
||||
|
||||
You will need to install gcc 4.3 and g++ 4.3. It appears that Cuda 3.0 SDK has not yet worked
|
||||
with gcc 4.4 and g++ 4.4. Please follow these steps:
|
||||
|
||||
sudo aptitude install gcc-4.3 g++-4.3
|
||||
cd ~/NVIDIA_GPU_Computing_SDK/C (go to SDK source dir. You should find the right path on your machine)
|
||||
mkdir mygcc
|
||||
cd mygcc
|
||||
ln -s $(which g++-4.3) g++
|
||||
ln -s $(which gcc-4.3) gcc
|
||||
|
||||
Note: mygcc directory must be created since I have made symlinks to the 4.3 compiler to mygcc directory
|
||||
in my current Makefile.
|
||||
|
||||
----------------------- Linux Makefile ----------------------
|
||||
|
||||
common.mk file needs to be edited on your machine before running. Please follow these steps:
|
||||
|
||||
1) Open "boinc/samples/nvcuda/common.mk" with gedit
|
||||
2) Ctrl+f and search for "tuanle". You will find the following:
|
||||
|
||||
ROOTDIR ?= /home/tuanle/NVIDIA_GPU_Computing_SDK
|
||||
|
||||
3) Replace this path with an appropriate path on your machine.
|
||||
4) Done!
|
||||
|
||||
|
||||
----------------------- Linux Troubleshooting ----------------
|
||||
|
||||
Error: ./example_app_nvcuda: error while loading shared libraries: libcudart.so.3: cannot open
|
||||
shared object file: No such file or directory
|
||||
Read: http://developer.download.nvidia.com/compute/cuda/3_0/docs/GettingStartedLinux.pdf (on top of page 6)
|
||||
Solution: export PATH=/usr/local/cuda/bin:$PATH
|
||||
export LD_LIBRARY_PATH=/usr/local/cuda/lib:$LD_LIBRARY_PATH
|
||||
|
||||
|
||||
----------------------- Run Executable file ------------------
|
||||
|
||||
"make" command will create an executable file in "boinc/samples/nvcuda/linux/release/".
|
||||
If your machine doesn't have CUDA-enabled GPU, then the executable file for this sample app in
|
||||
the release directory will stop execution after the statement "Start at inversion #1" is printed out on
|
||||
the terminal. In this case, it's best to run in emurelease mode. To generate an executable file in
|
||||
emurelease mode, type "make emu=1". The executable file is then created in "boinc/samples/nvcuda/linux/emurelease/".

----------------------- Mac OS Makefile ----------------------
|
||||
By default, the NVIDIA Cuda SDK for MacOS is installed at $ROOT/Developer/ under the directory name "GPU Computing".
|
||||
If it is installed somewhere else, then common_mac.mk file needs to be edited by the following steps:
|
||||
|
||||
1) Open "boinc/samples/nvcuda/common_mac.mk"
|
||||
2) Look for "ROOTDIR ?= /DeveloperGPU\ Computing"
|
||||
3) Replace this path with an appropriate path on your machine.
|
||||
4) Done!
|
||||
|
||||
----------------------- Mac Troubleshooting ----------------
|
||||
|
||||
Error: ./example_app_nvcuda_mac: library not found for -lcutil_i386.
|
||||
Solution: run make from "CPU Computing" directory to build the cutil_i386 library.
|
||||
|
||||
Note: It appears that nvcc compiler has trouble compiling .cu file that contains both BOINC and
|
||||
Cuda code. Any attempt to compile such .cu files will result in errors like the following:
|
||||
|
||||
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/mmintrin.h(55): error: identifier "__builtin_ia32_emms" is undefined
|
||||
|
||||
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/mmintrin.h(68): error: identifier "__builtin_ia32_vec_init_v2si" is undefined
|
||||
|
||||
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/mmintrin.h(111): error: identifier "__builtin_ia32_vec_ext_v2si" is undefined
|
||||
|
||||
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/mmintrin.h(150): error: identifier "__builtin_ia32_packsswb" is undefined
|
||||
|
||||
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/mmintrin.h(165): error: identifier "__builtin_ia32_packssdw" is undefined
|
||||
|
||||
...........
|
||||
|
||||
The solution that I came up with is to compile BOINC and Cuda seperately. Put BOINC code in .c file and CUDA code in .cu file.
|
||||
Then, write an external function in .cu file that will make kernel calls, do computation and return a result that could be used
|
||||
in .c file.
|
||||
|
||||
----------------------- Run Executable file ------------------
|
||||
|
||||
"make -f Makefile_mac" command will create an executable file in "boinc/samples/nvcuda/darwin/release/".
|
||||
If your machine doesn't have CUDA-enabled GPU, then the executable file for this sample app in
|
||||
the release directory will stop execution after some output statements on the terminal. In this case,
|
||||
it's best to run in emurelease mode. To generate an executable file in emurelease mode, type
|
||||
"make -f Makefile_mac emu=1". The executable file is then created in "boinc/samples/nvcuda/darwin/emurelease/".
|
||||
Note that NVIDIA Cuda SDK version older than version 3.0 will no longer support emulation mode.
|
||||
|
||||
Also, you need to define some environment variables before running the executable file.
|
||||
|
||||
export PATH=/usr/local/cuda/bin:$PATH
|
||||
export DYLD_LIBRARY_PATH=/usr/local/cuda/lib:$DYLD_LIBRARY_PATH
