CVE, CWE, and CAPEC databases and their relationships are shortly introduced. Focus on this paper is on formalization and more specific on weakness formaliza-tion. Software weaknesses are described as formatted text. There is no widely ac-cepted formal notation for weakness specification. This paper shows how Z-notation can be used for formal specification of CWE-119.
The state of queues in modern computing centers is such that a user's task can hold in the queue before start for weeks. However, even if the queuing system gives a forecast for the start of a task, the forecast often turns out to be incorrect. It is happening because during the week the task is in the queue, there are some events will occur that will change the moments tasks starts. We know...

Such system provides fast and efficient response for summary reports, monitoring tasks...
Containerization technology for Linux systems appeared many years ago with OpenVZ and LCX systems. However, wider usage came with the advent of the Docker system and the addition of new container support mechanisms to the Linux kernel itself. Originating as a system for servers, containerization technology has gradually moved into the user space as a universal mechanism for distributing and...

The training of teams and crews for the control and operation of complex technical objects implies the training of a big number of people at once, who must jointly solve the assigned tasks. Unlike a simple training system, such simulators are built on the basis of a distributed computing environment, consisting of the workplaces of the training crew members and the control server. In the case...

The network infrastructure is an integral part of the major research infrastructure project "Multifunctional Information and Computing Complex (MICC) of JINR". The main goal is to provide a guaranteed and reliable traffic transmission that will fully meet the needs of scientific experiments. This presentation provides an overview of the local and external network infrastructure at JINR.
Providing reliable Internet connection is the key to success of any network. In the current paper questions about highly reliable network topology for data transfer between nodes in JINR are considered. The big challenge for the network service is to integrate between the two GRID sites Tier 1 and Tier 2 data centers together with the backbone JINR LAN and upscaling data rates to 100G, and in...

Developing SSO and using it in JINR applications
One of the most important components of the monitoring system LITMon MICC LIT JINR is the data storage system. Initially, it was based on the RRD database and a special pnp4nagios plugin, support for which ended in 2022. Required features no longer work. The RRD database is morally obsolete and has ceased to meet performance requirements and has begun to consume more computing resources of the...
Executing millions of scientific high-throughput computing (HTC) jobs on distributed heterogeneous computing resources poses challenges in observing their status and behavior after their completion. To address this, an approach was developed to analyze jobs using scatter plots, showcasing the dependency between job durations and the relative performance of CPU cores they were assigned to....
Distributed systems require an efficient and reliable consensus mechanism to reach agreement between nodes. In recent years, two popular consensus algorithms, Practical Byzantine Fault Tolerance (PBFT) and Raft, have gained wide acceptance in the community due to their advantages. PBFT provides high speed and fault tolerance, while Raft is simple and easy to understand. However, each of them...

Scheduling tasks and allocating resources in a cloud (distributed) system is significantly different from resource management of a single computer. Cloud (global) schedulers view the system as a large pool of resources to which they have full access. At the same time, the most urgent task remains to maintain a balance, which consists in managing each individual computing task in such a way...
