Explain Optimizations:
G-HPL: adopted pipelined broadcast communication and promoted fine-grain overlapped data transfer G-RandomAccess: replaced MPI function calls with RDMA function calls, introduced 3-way data sorting and transfer to improve load imbalance, overlapped data transfer with data sorting, transformed data-sorting loop to use conditional move CPU instructions and applied loop distribution to table-updating loop S&EP-RandomAccess: applied loop distribution to table-updating loop and increased iterations of inner loops G-FFT: used the latest version of FFTE library EP-STREAM: inserted compiler directives to use a CPU feature of fast cache line allocation
