SGI

• 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.
