“…However, as the cost of commodity hardware is declining, combining HPC and HA architectures is becoming feasible to achieve HA cluster that is used for High Performance Computing. For instance, various techniques are currently available to have a redundant master node [3,12,13,15,18]. These implementations include active/active, active/hot-standby, and active/cold-standby nodes.…”

In recent years, we have witnessed a growing interest in high performance computing (HPC) using a cluster of workstations. This growth made it affordable to individuals to have exclusive access to their own supercomputers. However, one of the challenges in a clustered environment is to keep system failure to the minimum and to achieve the highest possible level of system availability. High-Availability (HA) computing attempts to avoid the problems of unexpected failures through active redundancy and preemptive measures. Since the price of hardware components are significantly dropping, we propose to combine both HPC and HA concepts and layout the design of a HA-HPC cluster, considering all possible measures. In particular, we explore the hardware and the management layers of the HA-HPC cluster design, as well as a more focused study on the parallel-applications layer (i.e. FT-MPI implementations). Our findings show that combining HPC and HA architectures is feasible, in order to achieve HA cluster that is used for High Performance Computing.

“…In fact, the entire Internet can be viewed as one truly huge cluster [3]. The third advantage is availability; replacing a "faulty node" within a cluster is trivial compared to fixing a faulty SMP component, resulting in a lower mean-time-to-repair (MTTR) for carefully designed cluster configuration [18]. On the other hand, HPCs are not problems-free.…”

In recent years, we have witnessed a growing interest in high performance computing (HPC) using a cluster of workstations. However, many challenges remain to be resolved before these systems become dependable. One of the challenges in a clustered environment is to keep system failure to the minimum level and while achieving the highest possible level of system availability. High-Availability (HA) computing attempts to avoid the problems of unexpected failures through active redundancy and preemptive measures. In this paper, we propose to build HAclusters based model for high performance computing. Our model is based on combination of both HPC and HA concepts, we also propose to investigate further the hardware and the management layers of the HA-HPC cluster design, and the parallel-applications layer (i.e. FT-MPI implementations). In this work, we focus upon the latter layer. We discuss our model, and present our simulation experiments we have carried out to evaluate our proposed model.
