Architecture of High-performance Computing Clusters
A high-performance computing (HPC) cluster is a powerful computing system consisting of interconnected computers working together to solve large and complex problems.
Hence, HPC clusters are used for various applications, including scientific research, engineering simulations, and financial modeling.
Components of HPC Clusters
Compute nodes
A fast interconnect connects several distinct servers or computers, collectively called nodes, to form an HPC cluster.
These components include the backbone of the cluster and are responsible for processing, storing, and computing data. Therefore, various kinds of nodes exist for several types of tasks.
Every single HPC cluster on this website has
- Users log in to a dedicated data transfer node, known as a head or login node
- Conventional compute nodes, which are for most computations
- "Fat" compute nodes with no less than 1TB RAM GPU nodes (calculations can be executed on both CPU cores and a Graphical Processing Unit on these nodes)
a switch using Infiniband to link every node
Types of compute nodes
Compute nodes mostly come in two varieties:
CPU nodes: The computations are carried out by these nodes using CPUs or central processing units. Applications that need a lot of serial processing usually use CPU nodes.
GPU nodes: Nodes perform the computations using GPUs or graphics processing units. Applications that can run in parallel on several GPUs are usually the ones that require GPU nodes.
Head node
This is the central management computer for the cluster.
Moreover, It is responsible for scheduling jobs, monitoring the cluster's health, and providing access to its resources.
Storage system
This enormous amount of data retrieval and storage necessitates a new strategy for HPC storage.
Therefore, It won't be enough to merely use little direct-attached storage on each server that is only available from that specific server.
Storage systems can be local to the compute nodes or shared by all nodes.
Legacy parallel file systems require significant expertise and infrastructure knowledge to be installed to be functional.
Therefore, the tasks would include installing different software on metadata servers (MDS), metadata targets (MDT), object storage servers (OSS), and object server targets (OST).
Different services need to be installed on other physical servers.
Performing these tasks can easily lead to operator mistakes and expose the need for more understanding of the overall HPC cluster architecture.
To take advantage of the most recent advancements in storage technology, these legacy systems must be upgraded and changed regularly.
For example, upgrading a small number of these many computers to add SSDs is a complicated task for these legacy parallel file systems.
Network
The network seamlessly transfers data between the compute nodes, head node, and storage system. Hence, it ensures the efficient performance of an HPC cluster.
Common HPC Network Topologies
InfiniBand
High-performance connectivity technology called InfiniBand was beneficial for HPC clusters. It is a well-liked option for HPC networks.
Moreover, it provides effective communication protocols, large bandwidth, and low latency.
Ethernet
To satisfy the requirements of HPC environments, Ethernet, the helpful networking technology, has also changed.
The bandwidth for HPC applications provides high-speed Ethernet variations like 400 Gigabit Ethernet (400 GbE) and 100 Gigabit Ethernet (100 GbE).
Hybrid Networks
HPC clusters may occasionally use a hybrid architecture that blends Ethernet and InfiniBand.
While Ethernet is for external connections to storage systems or management networks, InfiniBand is applicable for high-speed communication between computing nodes.
Factors Affecting HPC Network Performance
Cable Type: The type of network cable that we use can have a significant impact on performance. Therefore, Fiber optic cables, which offer lower latency and better transfer speeds than copper lines, are the superior choice.
Network switches: When directing data flow between nodes, network switches are essential. So, High-performance switches with low latency and large bandwidth are crucial for HPC networks.
Network Congestion: Data traffic that surpasses the network's capacity is network congestion, and it causes delays and a decline in performance. Therefore, Proper network configuration and traffic control strategies are essential to avoid congestion.
Optimizing HPC Network Performance
Network Monitoring: Monitoring key performance indicators like error rates, latency, and bandwidth usage. So one can spot possible bottlenecks and improve the network setup.
