摘要:

Each talk can be seen from the perspective of models or methods.In this one we will try to overview some recent results in the queueing-theoretic analysis of high-performance and distributed computing systems,conceptually combining models and methods into an incomplete puzzle of three levels: analytical,simulation,technical.

Matrix-analytic method and regenerative approach will cover the analytical level,while discrete-event simulation and regenerative estimation will be useful for simulation,and we will scratch the surface of technical modeling as well.We will discuss a simple yet analytically tricky model of a supercomputer,several models of distributed systems,and arrive at energy-performance tradeoffs.The results covered are fruits of joint research with Prof.Evsey Morozov,Prof.Srinivas Chakravarthy,Prof.Garimella Rama Murthy and others.

简介:

Alexander Rumyantsev is a senior researcher at the Telecommunications Lab of the Institute of Applied Mathematical Research,Karelian Research Centre of the Russian Academy of Sciences,and associate professor at Petrozavodsk State University.He received his PhD in 2012 under supervisemend of Dr.,Prof.Evsey Morozov,and MSc in Applied mathematics and informatics in 2008.His current research interests are in applied probability,stochastic modeling,stability and performance analysis of computing and communication systems.He was an invited speaker at numerous conferences and workshops,received a several best paper awards and served on a number of international conference organizing committees,including the PaCT (2015),ICWSNUCA (2018),SMARTY (2018),ICAAP&SP (2019),MAM (2019).Alex is also a vice CEO at the small software development company 'Arvata' aimed at business process analysis and web-based information systems implementation.
