    Master's thesis describe process of production compute cluster based on open source operating system as is Linux. Ready outcome is KVM virtual machine, which could be used to create high performance cluster using disk less node. To deploy this cluster is needed server with processor supporting virtualization and Linux x64 installed. It has to be connected with nodes in one LAN segment. Nodes are booting from main server over TCP/IP network using PXE so they Ethernet card has to support PXE technology. Deployed cluster uses MPICH2 library which is described by MPI standard. In cluster are used many protocols and services like Torque, DHCP, TFTP, DNS, NFS, LDAP.

    Modified honey bee algorithm with random selection of virtual machines for dynamic load balancing
    (Wydawnictwa AGH, 2025) Sharmah, Daisy; Bora, Kanak Chandra; Khakhlari, Junumoni
    Cloud workloads can overwhelm load balancers, leading to inefficiencies and performance issues. To address these challenges, the honey bee load-balancing algorithm is highly effective in enhancing cloud-resource allocation. Inspired by the foraging behavior of honey bees, this algorithm offers a dynamic approach to resource distribution that adapts to changing workloads in real time. This paper delves into the key features and advantages of honey bee load-balancing, focusing on its dynamic resource allocation, overall response time, and data center processing time. Through a comparative study of existing methodologies, we proposed a modified honey bee load-balancing algorithm that incorporated the random selections of virtual machines. Utilizing the CloudAnalyst tool for simulation, we compares traditional and proposed honey bee load-balancing algorithms to evaluate overall response times and data center processing times using user bases, data centers, virtual machine load balancers, time, service broker policies, and regions. The proposed algorithm demonstrates superior performance in these parameters as compared to the traditional approach when using the same metric values for both algorithms.

    The CC1 project - system for Private Cloud Computing
    (Wydawnictwa AGH, 2012) Chwastowski, Janusz; Grzymkowski, Rafał; Kruk, M.; Nabożny, Maciej; Natkaniec, Zbigniew; Olszewski, Andrzej; Pałka, H.; Sobocińska, Zofia; Sośnicki, Tomasz; Szostak, Michał; Syktus, Przemysław; Witek, Mariusz; Wójcik, Piotr; Wojtoń, Tomasz; Zdybał, Miłosz; Żabiński, Bartłomiej
    The main features of the Cloud Computing system developed at IFJ PAN are described. The project is financed from the structural resources provided by the European Commission and the Polish Ministry of Science and Higher Education (Innovative Economy, National Cohesion Strategy). The system delivers a solution for carrying out computer calculations on a Private Cloud computing infrastructure. It consists of an intuitive Web based user interface, a module for the users and resources administration and the standard EC2 interface implementation. Thanks to the distributed character of the system it allows for the integration of a geographically distant federation of computer clusters within a uniform user environment.

    Wydział Geologii, Geofizyki i Ochrony Środowiska
    In this paper, a load balancing issue for Cloud Computing based web servers was described. Author made review of the most popular (commercial and noncommercial) Cloud Computing systems. The EUCALYPTUS cloud and its use for parallel processing for web services was presented. The review of three load balancing algorithms (Request Counting, Weighted Traffic Counting and Pending Request Counting) was shown.

    UPnP-based discovery and management of hypervisors and virtual machines
    (Wydawnictwa AGH, 2011) Zieliński, Sławomir; Handzlik, Tomasz; Lewicki, Tomasz
    The paper introduces a Universal Plug and Play based discovery and management toolkit that facilitates collaboration between cloud infrastructure providers and users. The presented tools construct a unified hierarchy of devices and their management-related services, that represents the current deployment of users' (virtual) infrastructures in the provider's (physical) infrastructure as well as the management interfaces of respective devices. The hierarchy can be used to enhance the capabilities ofthe provider's infrastructure management system. To maintain user independence, the set of management operations exposed by a particular device is always defined by the device owner (either the provider or user).
