How do CUDA blocks/warps/threads map onto CUDA cores?
...blocks with 6 threads = 64 warps * 10 instructions = 640 instructions
In order to get optimal efficiency the division of work should be in multiples of 32 threads. The hardware will not coalesce threads from different warps.

How does this code generate the map of India?
... character. In the second, decimal 33 is ASCII for '!'. Toggling the low-order bit of 33 gives you 32, which is ASCII for a space. This causes ! to be printed if b is odd, and a blank space to be printed if b is even. The rest of the code is simply there to walk the "pointer" a through the strin...
