+# Example 01
+This example compares the timings of adding vectors on the CPU versus adding vectors on the GPU, the latter of which has different implementations.
+
+## Compiling
+
+```
+clang++ -std=c++0x -framework OpenCL version01.cpp -o version01.out
+```
+
+To ignore deprecation warnings, add the flag `-Wno-deprecated-declarations`.
+
+## About
+The code runs the following implementations of adding large vectors (131072 elements; 8 * 32 * 512). The vectors are added together 1000 times.
+
+- CPU
+- GPU, where 32 * 512 threads are spawned and each thread thus gets 8 elements to calculate
+- GPU, same as before but each iteration involves writing the buffers (to demonstrate overhead)
+- GPU, where 8 * 32 * 512 threads are spawned - one for each element
