  • Simulation examples (Hardship)
  • Bandwidth of copper wire doesn't keep up with bandwidth of processors.
  • Latency of conducts not improving.
  • Fibre optics not very fast. Only air core; but increases available bandwidth.
  • mpi_reduce >> mpi_waitall, mpi_reduce, mpi_barrier, mpi_recv.
  • Ethernet chip to offload communication.
  • Memory chip speeds have not increased.
  • Bandwidth/Latency.
  • Linux -> Computer frontend -> Matrix of computing resources.
