Summary
We started with an implementation of Conway's Game of Life, which gave us an idea of how the many threads of a CUDA kernel are organized in a block-grid tensor-type structure. We then delved into block-level synchronization by way of the CUDA function, __syncthreads(), as well as block-level thread intercommunication by using shared memory; we also saw that single blocks have a limited number of threads that we can operate over, so we'll have to be careful in using these features when we create kernels that will use more than one block across a larger grid.
We gave an overview of the theory of parallel prefix algorithms, and we ended by implementing a naive parallel prefix algorithm as a single kernel that could operate on arrays ...
