HPC Clusters

At Aspen Systems, our primary business is building and supporting custom high-performance computational clusters and solutions. We have the knowledge and expertise to deliver different types of proven, turn-key clusters built for your needs.

Our Value

Decades of successful HPC deployments

Architected For You

As a leading HPC provider, Aspen Systems offers a standardized build and package selection that follows HPC best practices. However, unlike some other HPC vendors, we also provide you the opportunity to customize your cluster hardware and software with options and capabilities tuned to your specific needs and your environment. This is a more complex process than simply providing you a “canned” cluster, which might or might not best fit your needs. Many customers value us for our flexibility and engineering expertise, coming back again and again for upgrades to existing clusters or new clusters which mirror their current optimized solutions. Other customers value our standard cluster configuration to serve their HPC computing needs and purchase that option from us repeatedly. Call an Aspen Systems sales engineer today if you wish to procure a custom-built cluster built to your specifications.

Solutions Ready To Go

Aspen Systems typically ships clusters to our customers as complete turn-key solutions, including full remote testing by you before the cluster is shipped. All a customer will need to do is unpack the racks, roll them into place, connect power and networking, and begin computing. Of course, our involvement doesn’t end when the system is delivered.

True Expertise

With decades of experience in the high-performance computing industry, Aspen Systems is uniquely qualified to provide unparalleled systems, infrastructure, and management support tailored to your unique needs. Built to the highest quality, customized to your needs, and fully integrated, our clusters provide many years of trouble-free computing for customers all over the world. We can handle all aspects of your HPC needs, including facility design or upgrades, supplemental cooling, power management, remote access solutions, software optimization, and many additional managed services.

Passionate Support, People Who Care

Aspen Systems offers industry-leading support options. Our Standard Service Package is free of charge to every customer. We offer additional support packages, such as our future-proofing Flex Service or our fully managed Total Service package, along with many additional Add-on services! With our On-site services, we can come to you to fully integrate your new cluster into your existing infrastructure or perform other upgrades and changes you require. We also offer standard and custom Training packages for your administrators and your end-users or even informal customized, one-on-one assistance.

HPC Storage

Storage is often an afterthought in many HPC designs.

When processor speed, memory, and interconnect considerations are the only design considerations for your next purchase, you run the risk of undermining the efficiency and reliability of your HPC solution by teaming it with an inadequate or poorly matched storage solution that becomes the performance bottleneck and limiting factor in system productivity.

To that end, Aspen teams with some of the best storage providers in the business to offer you the best solution for your specific storage needs. We partner with storage solution providers who provide distinct advantages, and are the industry leaders in their specialty areas.

Our Storage Partners


Cluster Networking is the backbone of a high-performance cluster solution.

If your cluster design requires a high-speed interconnect, either InfiniBand or Ethernet can provide network solutions with higher bandwidth and low latency, providing reliable, blazing-fast performance.

HPC clusters can utilize a single Ethernet network for administrative traffic, data sharing, and application processing traffic. If your applications are bandwidth or latency- sensitive, using an additional high-speed interconnect like InfiniBand for your cluster network is preferred to ensure that critical computational and data traffic is not hampered by other traffic.

InfiniBand networking is an industry-standard, channel-based, point-to-point switched fabric interconnect for high-performance networks. InfiniBand networks provide high-bandwidth, low-latency, and reliability with failover in a scalable, high-performance network with built-in security and quality of service. InfiniBand provides a high-speed interconnect from compute nodes to storage systems.

HPC Applications are specifically designed to take advantage of the parallel nature of high-performance computational computing systems. Algorithmically designed to take advantage of high-performance architecture, these applications can be run on your compute cluster with only minor customization. Some software packages will benefit from custom compilation, but most are commercial releases and don’t allow their source code to be distributed.

Aspen can install your choice of applications onto your cluster before it ships. We will install, configure, and performance tune your applications so that you can rest assured that you get every bit of performance from your cluster. Many factors affect how your specific applications will perform, such as your choice of interconnect and processor architecture. Your Aspen sales engineer can help you discover the optimal choices for your solution.

hpc cluster applications


High-performance cluster solutions work best when the software takes full advantage of the cluster environment. HPC optimized compiling tools are designed to optimize software for parallel-computing environments, so choosing the proper compiler is crucial to achieving optimal results. HPC technology has achieved excellent results through open-source operating systems. However, commercial compilers often offer the best possible performance results in cluster environments because these compilers are specifically suited to the processor and the architecture used in your operating environment. Our experts can help you choose the best option for your particular needs.

Schedulers and Tools

Cluster batch control systems are used to manage jobs on the system. They are essential for sequentially queuing jobs, assigning priorities, distributing, parallelizing, suspending, killing, or otherwise controlling jobs cluster-wide. SLURM is the most commonly used open-source job scheduler today. We also offer OpenPBS, Grid Engine, and other open-source solutions to fit your needs. Commercial products such as Adaptive Computing’s Moab-Torque and Altair’s PBS Professional and Grid Engine are also available. Aspen Systems has the knowledge and expertise to configure your scheduler of choice to get the uttermost efficiency out of your HPC cluster.
