Over at Information Management, Justin Kern has posted an interview with Bill Kramer, one of our Rock Stars of HPC and deputy director of the NSF’s Blue Waters supercomputer project at NCSA. The system is expected to deliver 9 Petaflops of performance, generating big data IO that Kramer describes as a primary challenge.
The methods that we develop and our vendor partners develop to deal with highly parallel things will be commonplace not too long from now. One big aspect to all of that is that bandwidth is the thing that’s becoming the most limited and the most expensive. You can build more and more processors, but what’s really limiting their ability to do sustained work is the bandwidth, which gets the data in and out of the systems.
