Explain Optimizations:
HPL: Custom Algorithm (mostly to take advantage of collectives). Special Assembly kernels and data format (replace factorization routines ... uses HPL's backsolve). FFT: Use of intrinsics (pseudo ASM instructions) to help the compiler. STREAMS: Assembly kernels MPIRandomAccess: Custom Algorithm (same as used on LLNL machine ... we will be following up on that front).
