In a world run by data, high-performance computing (HPC) is very important for almost every business type. With organizations’ continued efforts to harness big data, analytics, AI, and machine learning, the need for high-end GPUs for HPC workloads has soared. These specialized processors are the building blocks of today’s HPC systems and allow scientists, engineers, and data analysts to solve problems that were impossible to address before. Let’s read more about GPUs for HPC Workloads in the blog.
Applications: GPUs for HPC workloads
Loyal to their name, GPUS or Graphics Processing Units were originally developed to perform graphics-intensive computations for video games or professional visualization and modeling. However, due to fully parallel design, they are best suited for the enormous computational requirements of HPC applications. Whereas ordinary and older devices known as CPUs contain only hundreds of control processing units, while GPUs have thousands of such units, which are primarily designed to solve problems that require independent simultaneous calculations.
Changing the use of GPUs for HPC workloads in different working fields like scientific analysis, weather prediction, financial prognostication, and deep learning. This has led to unmatched growth of the demand of GPUs for HPC workloads in the HPC market. Global Market Insights also stated that the GPU market value was above $40 billion in 2022 and is expected to grow at a CAGR of 25% for 2023 to 2032, and may reach $400 billion in 2032.
Why GPUs for HPC workloads are important Computers
GPUs for HPC workloads offer several advantages over traditional CPU-based systems:
Parallel Processing
GPUs can address thousands of threads at once, which are perfect for parallel computations that are often met in HPC applications.
Energy Efficiency
Although today’s GPUs can demonstrate high performance, they are developed to consume minimum power, which is especially important for HW shared computing infrastructures.
Accelerated Computations
Using GPus can quickly solve intricate equations hence increasing the time taken to analyze data and conduct simulations.
Scalability
What’s more about these systems is that they can be scaled up simply by adding more GPUs that can fit an organization’s computational requirements at any one point in time.
Versatility
GPUs for HPC workloads can be used in various applications that are related to AI and machine learning, scientific computation, and simulations, and data analysis.

Selecting the Correct GPU for Your High-Performance Computing Deployments
When selecting GPUs for HPC workloads, several factors should be considered:
Performance Requirements
Determine the particular computational requirements of your intended HPC applications. Per workload basis, applications could have high demand in double-precision, which one might not need in any AI workload.
Memory Capacity and Bandwidth
High-performance computing typically centers on data intensive applications. Make sure that the selected GPUs for HPC workloads have enough memory and memory bandwidth that is required to cater for your data.
Power Efficiency
Think of power consumption of the GPUs for HPC workloads, especially for large scale scientific computing where power cost might be on the higher side.
Software Ecosystem
Examine the software support and environment for each GPU. It was identified that a strong number of libraries and tools in higher computing performance can go a long way in boosting up the performance.
Scalability
Think about how this GPU belongs to multi-WPU solutions and if it has NVLink or Infinity Fabric connection to other GPUs.
Cost
It all ties back to the idea of achieving performance while staying within the proper operating budget. These include the cost of the hardware, electrical power consumption, and possible software license costs.
The hardware architecture for GPU will remain a focal area for development and improvements that are feasible in the near future include better energy efficiency metrics, improved memory band-width and the integration of stronger AI capacities.

While performance metrics like memory size and total memory bandwidth and other constraints like power consumption and software compatibility need to be taken into consideration for GPU selection, a tailor-made field study for particular HPC applications might show a better ROI for other GPUs that aren’t popular for HPC but are cheaper or better in other ways depending on their specific needs.
FAQ
Is there a fundamental distinction between game playing GPUs and GPUs for HPC workloads?
HPC workloads are scientific and engineering-related, which is opposite to gaming, so HPC GPUs are accordingly different from the latter. They usually contain more memory, and their calculations are more precise as well as concentrate on double-precision floating points.
A common question is whether it is acceptable to use consumer-oriented GPUs for HPC workloads
This is feasible for somewhat small-scale projects, but consumer-grade GPUs cannot be advised for professional or large-scale HPC use. They do not come with HPC essentials such as ECC memory, high 2PS performance indication, big memory citable, and HPC-specific interconnect.
Is the application of GPUs in HPC systems, in some ways, that?
Actually, the GPUs for HPC workloads offload the HPC tasks through parallel processing, which means that they perform numerous simple calculations at the same time.
