In this paper we describe a new framework for creating distributed programmes which are resilient to cluster node failures. Our main goal is to create a simple and reliable model, that ensures continuous execution of parallel programmes without creation of checkpoints, memory dumps and other I/O intensive activities. To achieve this we introduce multi-layered system architecture, each layer of which...
Nowadays many job schedulers rely on checkpoint mechanisms to make long-running batch jobs resilient to node failures. At large scale stopping a job and creating its image consumes considerable amount of time. The aim of this study is to propose a method that eliminates this overhead. For this purpose we decompose a problem being solved into computational microkernels which have strict hierarchical...
Nowadays, many cluster management systems rely on distributed consensus algorithms to elect a leader that orchestrates subordinate nodes. Contrary to these studies we propose consensus-free algorithm that arranges cluster nodes into multiple levels of subordination. The algorithm structures IP address range of cluster network so that each node has ranked list of candidates, from which it chooses a...
Virtual private supercomputer is an efficient way of conducting experiments on high-performance computational environment and the main role in this approach is played by virtualization and data consolidation. During experiment virtualization is used to abstract application from underlying hardware and also from operating system offering consistent API for distributed computations. In between experiments...
