Whether being built for capacity or capability, the conventional wisdom about memory provisioning on the world’s fastest systems is changing quickly. The rise of 3D memory has thrown a curveball into the field as HPC centers consider the specific tradeoffs between traditional, stacked, and hybrid combinations of both on next-generation supercomputers. In short, allocating memory on these machines is always tricky—with a new entrant like stacked memory into the design process, it is useful to gauge where 3D devices might fit.
While stacked memory is getting a great deal of airplay, for some HPC application areas, it might fall just …Read more
