Waiting – Not Precisely Patiently – For Exascale
There was an outside chance that China might pull a surprise on the HPC community and launch the first true exascale system – meaning capable of more than 1 exaflops of peak theoretical 64-bit floating point performance if you want to be generous, and 1 exaflops sustained on the High Performance Linpack (HPL) benchmark if you don’t – but that didn’t happen. …

The Many Facets Of Hybrid Supercomputing As Exascale Dawns
There may not be a lot of new systems on the November 2020 edition of the Top500 rankings of supercomputers, but there has been a bunch of upgrades and system tunings of machines that have been recently added, expanding their performance, as well as a handful of new machines that are interesting in their own right. …

Arm And Japan Get Their Day In The HPC Sun
There is a constant push and pull between budget and architecture in supercomputing, and the passing of time has not made anyone’s arms tired as yet on both sides of the bargaining table. …

The Supercomputing Efficiency Curve Bends In The Right Direction
Things get a little wonky at exascale and hyperscale. Things that don’t matter quite as much at enterprise scale, such as the cost or the performance per watt or the performance per dollar per watt for a system or a cluster, end up dominating the buying decisions. …

The Calm Before The Exascale Storm
The latest list of the world’s top 500 floppiest supercomputers was released this week and the biggest news to report is that there is almost no news to report. …

Supercomputing Coiled To Spring To Exascale
If you want to rank in the world of supercomputing – as national and state governments as well as academic and research institutions most certainly do to prove their worth for research and development – then you need to have at least a petaflops ante now to play the game. …
