1. Rename the shell script extension from .sh to .command
2. Make the file executable: chmod +x file.command
3. Wherever you put the file, it will run with your home directory as the current working directory. To get around this, use the following line:
   cd “`dirname “$0″`”

find . -iname “*.cpp” -print | xargs grep “main(” -s

-s = silent – no error messages

ssh -N -L 4001:destination.machine.de:3389 user@gateway.machine.de

Forward local port 4001 to gateway.machine.de, and tell him to send this to destination.machine.de, on port 3389

1. Get CUDA Toolkit version 1.1, CUDA SDK version 1.1 for Linux and NVIDIA Driver for Linux with CUDA Support from NVIDIAs CUDA Zone.
2. Install the Toolkit and the SDK as root by executing the *.run files.
3. Add the location of the CUDA binaries (nvcc) to your PATH environment variable and the location of the CUDA libraries to your LD_LIBRARY_PATH environment variable:
   export PATH=$PATH:<CUDA_INSTALL_PATH>/bin
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<CUDA_INSTALL_PATH>/lib
4. If you have no NVIDIA card installed you need to extract the libcuda.so library from the Driver bundle by executing the driver’s .run file with the option
   ‘–extract-only’
   Copy the /lib/*.so files of the driver packages to the other CUDA libraries (/usr/local/cuda/lib).
   Add a symbolic link:
   ‘sudo ln -s libcuda.so.169.09 libcuda.so’
   (In my case the lib is named “libcuda.so.169.09”. It my be different on your system.)
5. Go to the SDK directory and run make with emulation option enabled:
   ‘make emu=1’ or ‘make emu=1 dbg=1′ for debug mode
6. Run the examples in ./bin/linux/emurelease …
