Early Frontier Supercomputer Tests Show Decent Performance Leaps
It is the nature of capability class supercomputers to try to push the envelope on as many different architectural fronts as possible. …

For more than three decades, researchers have used a particular simulation method for molecular dynamics called Ab initio molecular dynamics, or AIMD, which has proven itself to be the method most accurate for analyzing how atoms and molecules move and interact over a fixed time period. …
Yesterday with the announcement of the forthcoming El Capitan supercomputer, which is set to be more powerful than the top 200 supercomputers combined, we got to thinking about a critical issue that is far less attention-capturing than big performance numbers. …
The widening performance disparity between compute and I/O is not likely to get any better in the fast-approaching exascale era. …
Throughout the many different types of system architecture in the past six decades, one thing has always remained true: Hardware always gets ahead of software, and rather than be too annoyed about it, there is another thing that is also true. …
For exascale hardware to be useful, systems software is going to have to be stacked up and optimized to bend that hardware to the will of applications. …
To effectively make use of the level of concurrency in forthcoming exascale systems – hundreds of thousands of compute elements with millions of threads – requires some new thinking, both by programmers and in development tools. …
We have spent the past several years speculating about what the “Summit” supercomputer built by IBM, Nvidia, and Mellanox Technologies for the US Department of Energy and installed at Oak Ridge National Laboratory might be. …
IBM and the other vendors who are bidding on the CORAL2 systems for the US Department of Energy can’t talk about those bids, which are in flight, and Big Blue and its partners in building the “Summit” supercomputer at Oak Ridge National Laboratory and “Sierra” at Lawrence Livermore National Laboratory – that would be Nvidia for GPUs and Mellanox Technologies for InfiniBand interconnect – are all about publicly focusing on the present, since these two machines are at the top of the flops charts now. …
OpenACC is one of the prongs in a multi-prong strategy to get people to port the parallel portions of HPC applications to accelerators. …
