Hardware acceleration of number theoretic transform for zk‐SNARK

open access: yesEngineering Reports, EarlyView., 2023
An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Calculation of time characteristics for acyclic fork-join queueing network [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
An open acyclic fork-join queueing network is considered. When a job arrives from a source into the network, it is split to be serviced into a given constant number of associated tasks.

Queueing Systems with Random Volume Customers and their Performance Characteristics

open access: yesJournal of Information and Organizational Sciences, 2021
In the paper, we consider non-classical queueing systems with non-homogeneous customers. The non-homogeneity we treat in the following sense: in systems under consideration, we characterize each customer by random capacity (volume) that can have an ...

Models of group poisson flows in telecommunica-tion traffic control

open access: yesВестник Самарского государственного технического университета. Серия: Технические науки, 2020
The lack of effectiveness of the use of models of self-similar processes to the analysis of queues telecommunications systems is presented. The evolution of the flow models managed by Markovs chain is considered. The specifics of the use of Markovs flows
