Example: Basic

This example covers the basic features of the CUDA language:

• defining a kernel (__global__ basicSum())
• using CUDA APIs such as cudaMalloc(), cudaFree() and cudaMemcpy()
• launching a kernel

The example consists of:

• Generating test data on the host
• Sending data to the device
• Launching a kernel on the device
• Receiving data back from the device
• Checking that the data we received is what we expect

Build and run the example by following the general instructions.
