1. Multi- and many-core architectures have experienced widespread use in desktop and HPC systems. Provide justification to the following points

a) In August 2018 AMD launched their Ryzen Threadripper 2990WX processor with 32 cores and 64 threads, while NVIDIA released their V100 with 5120 and 640 CUDA and Tensor cores respectively at the end of 2017. Critically contrast the differences between multi-core CPUs, GPUs, and Tensor architectures.

b) Explain why parallel programming cannot match the progress of processor technology.

c) Suggest ideas and defend your argument using plausible solutions for core scaling, effective programming using multi-core technologies.

2. The standard Linpack benchmark employed for the Top500 list solves a dense mxm system of linear equations. The time complexity for the sequential algorithm can be approximated by 2/3m3+2m2. Assuming there is a MPI parallel Linpack code which requires:
