HPC Clusters - High-Performance Computing Clusters for High Demands

HPC clusters are typically found in technical and scientific environments such as universities, research institutions, and corporate research departments. Often the tasks performed there, such as weather forecasts or financial projections, are broken down into smaller subtasks in the HPC cluster and then distributed to the cluster nodes.

The cluster's internal network connection is important because the cluster nodes exchange a lot of small pieces of information. These have to be transported from one cluster node to another in the fastest way possible. This means, the latency of the network must be kept to a minimum. Another important aspect is that the required and generated data can be read or written by all cluster nodes of an HPC cluster at the same time.

Structure of an HPC Cluster

The cluster server, which is called the master or frontend manages the access and provides programmes and the home data area.
The cluster nodes do the computing.
A TCP network is used to exchange information in the HPC cluster.
A high-performance network is required to enable data transmissions with very low latency.
The High Performance Storage (Parallel File System) enables the simultaneous write access of all cluster nodes.
The BMC Interface (IPMI Interface) is the access point for the administrator to manage the hardware.

All cluster nodes of an HPC cluster are always equipped with the same processor type of the selected manufacturer. Usually different manufacturers and types are not combined in one HPC cluster. A mixed configuration of main memory and other resources is also possible. However, this should be taken into account when configuring the job control software.

HPC Clusters

Where should HPC be used?

HPC clusters are most effective if they are used for computations that can be subdivided into different subtasks. An HPC cluster can also handle a number of smaller tasks in parallel. A high-performance computing cluster is also able to make a single application available to several users at the same time in order to save costs and time by working simultaneously.

Depending on your budget and requirements, HAPPYWARE will be happy to build an HPC cluster for you – with various configured cluster nodes, a high speed network, and a parallel file system. For the HPC cluster management, we rely on the well-known OpenHPC solution to ensure effective and intuitive cluster management.

If you would like to learn more about possible application scenarios for HPC clusters, our IT and HPC Cluster expert Jürgen Kabelitz will be happy to help you. He is the head of our cluster department and is available to answer your questions on +49 4181 23577 79.
