On the spatiotemporal behavior in biology-mimicking computing systems
János Végh, Ádám J. Berki
The payload performance of conventional computing systems, from single processors to supercomputers, reached its limits the nature enables. Both the growing demand to cope with "bi…
Do we know the operating principles of our computers better than those of our brain?
János Végh, Ádám J. Berki
The increasing interest in understanding the behavior of the biological neural networks, and the increasing utilization of artificial neural networks in different fields and scales…
Finally, how many efficiencies supercomputers have? And, what do they measure?
János Végh
Using an extremely large number of processing elements in computing systems leads to unexpected phenomena, such as different efficiencies of the same system for different tasks, th…
The performance wall of parallelized sequential computing: the dark performance and the roofline of performance gain
János Végh
The computing performance today is developing mainly using parallelized sequential computing, in many forms. The paper scrutinizes whether the performance of that type of computing…
The need for modern computing paradigm: Science applied to computing
János Végh
More than hundred years ago the 'classic physics' was it in its full power, with just a few unexplained phenomena; which however led to a revolution and the development of the 'mod…
Limitations of performance of Exascale Applications and supercomputers they are running on
János Végh
The paper highlights that the cooperation of the components of the computing systems receives even more focus in the coming age of exascale computing. It discovers that inherent pe…
Renewing computing paradigms for more efficient parallelization of single-threads
János Végh
Computing is still based on the 70-years old paradigms introduced by von Neumann. The need for more performant, comfortable and safe computing forced to develop and utilize several…
Statistical considerations on limitations of supercomputers
János Végh
Supercomputer building is a many sceene, many authors game, comprising a lot of different technologies, manufacturers and ideas. Checking data available in the public database in a…
How Amdahl's low restricts supercomputer applications and building ever bigger supercomputers
János Végh
This paper reinterprets Amdahl's law in terms of execution time and applies this simple model to supercomputing. The systematic discussion results in practical formulas enabling to…
Can Broken Multicore Hardware be Mended?
János Végh
A suggestion is made for mending multicore hardware, which has been diagnosed as broken.
A new kind of parallelism and its programming in the Explicitly Many-Processor Approach
János Végh
The processor accelerators are effective because they are working not (completely) on principles of stored program computers. They use some kind of parallelism, and it is rather ha…
Comments on the parallelization efficiency of the Sunway TaihuLight supercomputer
János Végh
In the world of supercomputers, the large number of processors requires to minimize the inefficiencies of parallelization, which appear as a sequential part of the program from the…
A figure of merit for describing the performance of scaling of parallelization
János Végh, Péter Molnár, József Vásárhelyi
With the spread of multi- and many-core processors more and more typical task is to re-implement some source code written originally for a single processor to run on more than one…
A configurable accelerator for manycores: the Explicitly Many-Processor Approach
János Végh
A new approach to designing processor accelerators is presented. A new computing model and a special kind of accelerator with dynamic (end-user programmable) architecture is sugges…
