Software challenges in extreme scale systems

Vivek Sarkar, William Harrod, Allan E Snavely
2009 Journal of Physics, Conference Series  
Carlson is a member of the research staff at the IDA Center for Computing Sciences where, since 1990, his focus has been on applications and system tools for large-scale parallel and distributed computers  ...  them, and scaling multiple chips to complete systems, for a range of real system applications, from highly scalable deep space exploration to trans-petaflops level supercomputing.  ...  These numbers are derived from the following: -For all applications, bisection bandwidth should be no less than current 3-D topologies scaled to a petaflop/s performance rates.  ...

Mesoscopic simulations at the physics-chemistry-biology interface [article]

Massimo Bernaschi, Simone Melchionna, Sauro Succi
2019 arXiv   pre-print
We discuss the Lattice Boltzmann-Particle Dynamics (LBPD) multiscale paradigm for the simulation of complex states of flowing matter at the interface between Physics, Chemistry and Biology.  ...  on Tsubame (2012), up to a world-record (to the best of our knowledge) of 20 PetaFlops/s (sustained performance) for protein crowding on Titan (2013).  ...  In fact, scaling up the size L by a factor 10 would take to the order of Exaflops, still feasible on present-day leading-edge Petaflops/s computers.  ...

At present the energy consumption of a Petaflops/s system is about a few megawatts. For example, the power consumption of the 1 Petaflop/s Blue Gene system JUGENE is about 2 megawatt (MW).  ...  The leading system of the June 2011 Top 500 list has a power consumption of 10 MW for a peak performance of 8 Petaflops/s.  ...

Machine Learning Parallelism Could Be Adaptive, Composable and Automated

Hao Zhang

We examine them and show that they significantly boost the efficiency or scalability of ML training on clusters 2-10x in their applicable scenarios.  ...  Particularly, ML scale-up is usually underestimated in terms of the amount of knowledge and time required to map from an appropriate distribution strategy to the model.  ...  This figure measures the computational cost using the metric Petaflop/s-days, which consists of performing 10 15 neural net operations per second for one day, or a total of about 10 20 operations.  ...
