متن کاملToward petascale earthquake simulations
Earthquakes are among the most complex terrestrial phenomena, and modeling of earthquake dynamics is one of the most challenging computational problems in science. Computational capabilities have advanced to a state where we can perform wavefield simulations for realistic three-dimensional earth models, and gain more insights into the earthquakes that threaten California and many areas of the w...
متن کاملI/O-aware bandwidth allocation for petascale computing systems
In the Big Data era, the gap between the storage performance and an application’s I/O requirement is increasing. I/O congestion caused by concurrent storage accesses from multiple applications is inevitable and severely harms the performance. Conventional approaches either focus on optimizing an application’s access pattern individually or handle I/O requests on a low-level storage layer withou...
متن کاملExtremely Scalable Spiking Neuronal Network Simulation Code: From Laptops to Exascale Computers
State-of-the-art software tools for neuronal network simulations scale to the largest computing systems available today and enable investigations of large-scale networks of up to 10 % of the human cortex at a resolution of individual neurons and synapses. Due to an upper limit on the number of incoming connections of a single neuron, network connectivity becomes extremely sparse at this scale. ...
متن کاملOn the benefit of dedicating cores to mask I/O jitter in HPC simulations
With exascale computing on the horizon, the performance variability of I/O systems presents a key challenge in sustaining high performance. In many HPC applications, I/O is performed concurrently by all processes; this produces I/O bursts, which causes resource contention and substantial variability of I/O performance, significantly impacting the overall application performance. We here utilize...
