Introduction to Parallel Programming class code

Building on OS X

These instructions are for OS X 10.9 "Mavericks".

• Step 1. Build and install OpenCV. The best way to do this is with Homebrew. However, you must slightly alter the Homebrew OpenCV installation; you must build it with libstdc++ (instead of the default libc++) so that it will properly link against the nVidia CUDA dev kit. This entry in the Udacity discussion forums describes exactly how to build a compatible OpenCV.

• Step 2. You can now create 10.9-compatible makefiles, which will allow you to build and run your homework on your own machine:

mkdir build
cd build
cmake ..
make

Note that it needs to be compiled with cuda 12.6. Otherwise the cuda kernel is not launched => I haven't figured out why

How to build and run lesson code snippet

Here is an example for Lesson 2 Code Snippet

nvcc -lineinfo hello_blockIdx.cu -o example1.exe

./example1.exe
