process of building faster machines is crippled by input/output units.
I/O is not scaling as fast as Moore’s Law. Research is being conducted
on improving the design and performance of parallel file systems,
including introducing solid state drives. Other challenges include the
search for experts in computational science, mathematics, and computer science to understand these complex systems and design software for taking advantage of the enormous computing power that
these supercomputers provide. As the future unfolds, it will be interesting to see what we will accomplish next.
I would like to thank my advisor Dr. John A. Chandy for providing input and sharing his experiences and opinions.
Sumit Narayan is a PhD candidate at the University of Connecticut,
