In this exercise we will implement a Jacobi iteration which is a very simple finite-difference scheme. Familiarize yourself with the provided skeleton. Then implement following things:
- Write the missing CUDA kernel
sweepGPUthat implements the same algorithm as the sweepCPU function. Check that the reported averate difference is in the order of the numerical accuracy. - Experiment with different grid and block sizes and compare the execution times.
Use the
nvvpto check how you modifications affect the execution.
