This document discusses cloud computing environments for high performance applications. It begins with an introduction to high performance computing and how cloud computing can provide scalable resources for HPC applications at a lower cost compared to traditional on-premise HPC systems. It then discusses different types of HPC applications and their requirements in more detail. The document also examines cluster-based HPC systems and Google's architecture for HPC in the cloud. It provides a performance analysis of several HPC cloud vendors and concludes with case studies of running HPC applications in the cloud.
BUILDING A PRIVATE HPC CLOUD FOR COMPUTE AND DATA-INTENSIVE APPLICATIONSijccsa
Traditional HPC (High Performance Computing) clusters are best suited for well-formed calculations. The
orderly batch-oriented HPC cluster offers maximal potential for performance per application, but limits
resource efficiency and user flexibility. An HPC cloud can host multiple virtual HPC clusters, giving the
scientists unprecedented flexibility for research and development. With the proper incentive model,
resource efficiency will be automatically maximized. In this context, there are three new challenges. The
first is the virtualization overheads. The second is the administrative complexity for scientists to manage
the virtual clusters. The third is the programming model. The existing HPC programming models were
designed for dedicated homogeneous parallel processors. The HPC cloud is typically heterogeneous and
shared. This paper reports on the practice and experiences in building a private HPC cloud using a subset
of a traditional HPC cluster. We report our evaluation criteria using Open Source software, and
performance studies for compute-intensive and data-intensive applications. We also report the design and
implementation of a Puppet-based virtual cluster administration tool called HPCFY. In addition, we show
that even if the overhead of virtualization is present, efficient scalability for virtual clusters can be achieved
by understanding the effects of virtualization overheads on various types of HPC and Big Data workloads.
We aim at providing a detailed experience report to the HPC community, to ease the process of building a
private HPC cloud using Open Source software.

Cloud deployment models: public, private, hybrid, community – Categories of cloud computing: Everything as a service: Infrastructure, platform, software - Pros and Cons of cloud computing – Implementation levels of virtualization – virtualization structure – virtualization of CPU, Memory and I/O devices – virtual clusters and Resource Management – Virtualization for data center automation.
In this paper we are study-ing about cloud computing, their types, need to use cloud computing. We also study the architecture of the mobile cloud computing. So we included new techniques for backup and restoring data from mobile to cloud. Here we proposed to apply some compres-sion technique while backup and restore data from Smartphone to cloud and cloud to the Smartphone.
The existing concept of virtualization provides increased system utilization via virtual infrastructure and promotes resource
sharing across an organization. To maximize the effective use of resources, cloud computing is used which uses service oriented architecture
infrastructure with on demand provisioning of software, platform and infrastructure as service. Dynamic service management is achieved by
implementing the cloud where dynamically scalable resources are provided as a service over the internet. This can be viewed as an
extension of grid computing, combined with utility computing and autonomic computing which helps an organization in converting the
capital expenditure into utility expenditure. This paper focuses on the basics of cloud computing technology.
Comparison of Several IaaS Cloud Computing Platformsijsrd.com
Today, the question is less about whether or not to use Infrastructure as a Services (IaaS), but rather which providers to use. Cloud infrastructure services, known as Infrastructure as a Service (IaaS), are self-service models for accessing, monitoring, and managing remote data center infrastructures, such as compute, storage, networking, and networking services. Instead of having to purchase hardware outright, users can purchase Infrastructure as a Service (IaaS) based on consumption, similar to electricity or other utility billing. Most providers offer the core services of server instances, storage and load balancing. When choosing and evaluating a service, it is important to look at issues around location, resiliency and security as well as the features and cost. In order to evaluate which provider best suits requirements.
Could the “C” in HPC stand for Cloud?This paper examines aspects of computing important in HPC (compute and network bandwidth, compute and network latency, memory size and bandwidth, I/O, and so on) and how they are affected by various virtualization technologies.

Privacy preserving public auditing for secured cloud storagedbpublications
As the cloud computing technology develops during the last decade, outsourcing data to cloud service for storage becomes an attractive trend, which benefits in sparing efforts on heavy data maintenance and management. Nevertheless, since the outsourced cloud storage is not fully trustworthy, it raises security concerns on how to realize data deduplication in cloud while achieving integrity auditing. In this work, we study the problem of integrity auditing and secure deduplication on cloud data. Specifically, aiming at achieving both data integrity and deduplication in cloud, we propose two secure systems, namely SecCloud and SecCloud+. SecCloud introduces an auditing entity with a maintenance of a MapReduce cloud, which helps clients generate data tags before uploading as well as audit the integrity of data having been stored in cloud. Compared with previous work, the computation by user in SecCloud is greatly reduced during the file uploading and auditing phases. SecCloud+ is designed motivated by the fact that customers always want to encrypt their data before uploading, and enables integrity auditing and secure deduplication on encrypted data.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
