HPC at centers like NCSA have a much lower latency interconnect than what is used by Amazon, Google, etc. and there are some computational problems that require the lower latency interconnect. Newer Intel chips will be integrating low-latency interconnects so in the future, Amazon, Google might be adopting low-latency interconnect computing.
