I/O performance has perpetually lagged well behind that of processors. This gap is made even more pronounced in the field of high-performance computing. While simply adding more network bandwidth and increasing the number of storage units is a simple way to increase theoretical peak I/O bandwidth, the software libraries for...
Modern cosmological simulations are some of the world's largest and most demanding numerical computations that are run on state-of-the-art supercomputers. The codes use N-body and mesh-based methods in gravity-only solvers, and both Lagrangian and Eulerian schemes to model gas dynamics. Even complex astrophysical effects such as of star formation and...
