Graphics Processing Units (GPUs) are built to speed up the process by which a computer creates and renders images intended for output to a display device. In addition to this, GPUs also ensure that graphics are displayed properly and work to enhance graphic performance. GPUs live in all kinds of technology hardware, from computers to laptops to cellphones and gaming consoles.

When it comes to working with a vendor to build a custom high performance system, selecting each component specifically for your needs is extremely important. We work with our clients to determine their needs and help them pick each component specifically for their workloads, but it’s always great when our clients have some familiarity with the pieces of their system. Below we breakdown some important things that we look at when helping our clients pick the right GPU.

NVIDIA has recently released a new series of graphics cards, the GeForce RTX™ 30 Series. This series is the second generation of the NVIDIA RTX PC gaming platform, and regarded as the fastest discrete graphics memory graphics card on the market today.

Building a high performance computing cluster for your specific needs used to be easier said than done, but we’re making strides to change that. With organizations needing their own HPC and big data systems now more than ever before, it’s important that the process of identifying what kind of system you need be as simple as possible, especially those in the engineering space that are working day after day to solve the world’s problems. This means that engineering organizations, particularly Ansys users, need systems that are designed to run exactly as they need them to, for their unique purposes. Here are five things Ansys users should consider when configuring a custom HPC cluster:

Analyzing User Needs

How many users? What type of jobs will they be running? Are some users priority over others? Being able to set user expectations on utilization of the system cannot be overstated. If you have hundreds of users, then be sure to budget and build a machine that can easily meet this demand. If some users have higher priority than others, make sure this information is available to the manufacturer, as the job scheduler will need to be setup and configured correctly.

Technical Capability of Users

Are all users comfortable with a consolidated HPC environment? Are they mostly Windows or Linux? Will there be a dedicated systems administrator? The answers to these questions will have a direct impact on the direction you take when it comes to choosing the right HPC cluster vendor.

HPC Cluster Hardware

Most Ansys users typically require a fair amount of computing power. This means that selecting the right number of cores, memory and high speed network backplane is critical to a successful deployment. We’ve found that fewer cores per node paired with a higher clock speed is typical because of the way that Ansys licenses their software applications. AMD EPYC CPUs offer a significant jump in GHz speed per core, while still maintaining reasonable cost.

With the minimum amount of memory being 2 GB memory per processor core, and Ansys users tending to use 6 GB memory per core or more, it’s important that memory configuration be optimized for maximum bandwidth.

Additionally, one node should be dedicated to visualization. Be sure to include a NVIDIA Quadro GPU in the “Head Node” or dedicated “Viz Node” to meet this need.

Determining Budget

In order to maximize your budget, this needs to be determined as early as possible. Establishing budget early on means that you are able to prioritize which components of your system are most important. If you need a machine with thousands of cores, but are operating under a limited budget, your vendor can help you identify trade-offs within the system that can make this possible.

Selecting Vendor

There are many options when it comes to selecting an HPC vendor, from cloud providers to Tier 1s to smaller, specialized HPC manufacturers. For users that just need to run a jump or two once in a while, cloud resources may be enough. But often times, these same users reach a certain usage level that makes the cost of cloud computing unreasonably high, and that usage level threshold is often much lower than users anticipate.

Nearly all cost calculators will eventually point you in the direction of purchasing a dedicated piece of hardware if you accurately account for the workloads you’ll be running on your cluster. In fact, most buyers find that the cost of buying a dedicated HPC cluster pays for itself when compared to 6-8 months of consistent cloud-usage. This means that most Ansys users end up turning away from cloud computing options during this discovery phase, and rightfully so. They then begin comparing the trade-offs of working with a Tier 1 manufacturer versus a company that specializes in delivering HPC clusters to Ansys end users.

With years of experience providing high performance computing clusters to Ansys end users, our engineers here at PSSC Labs listen to the specific needs of our clients and then work with them to customize a solution, within any time and budgetary constraints. Our PowerWulf ZXR1+ HPC Cluster is the cluster that many of our Ansys users end up purchasing, and for good reason – it’s application-optimized, scalable, and delivered production ready.

All in all, there are several things to consider when selecting or building a custom HPC cluster. That’s why it’s even more important to work with the right partner – one that can listen to your unique business needs and help you build a system that will perform exactly as you need it to, without the sky high costs of Tier 1 manufacturers.

High performance computing (HPC) generally refers to the practice of aggregating computing power in a way that delivers higher performance than one could get from a typical workstation or desktop computer, in an effort to solve problems in a variety of fields – business, science, engineering, and more. Over the past few decades, high performance computing has changed the way we perform research by speeding up the processes by which we can collect, manage, store, process, and analyze information. It’s fair to say that without advancements made by HPC products, research in many areas would have come to a screeching halt many years ago, and this is particularly true of the life sciences industry.

The life sciences space is dominated by data analytics. Almost all HPC work is comprised of large data sets that have extensive storage and networking requirements to handle real-time influxes from various sources. This means systems working on life science research projects need a surplus of processing power.

How HPC is Changing the Life Science Industry

The availability of high performance computing systems in the life science industry presents an opportunity of economic competitiveness and scientific discovery. With HPC being the technology at the forefront of scientific research, it’s truly positioned to help life science organizations pioneer new solutions to the world’s heath problems – something we’ll all find so relevant in these times.

HPC and big data technologies allow research organizations the opportunity to drastically accelerate discovery life cycles across the life science industry, through scenarios such as:

• Chemistry: bio-chemistry, molecular modeling, etc.
• Bio-engineering: agricultural engineering
• Genomics: complex disease genomics, agrigenomics, oncology, microbial genomics, etc.
• Biology: molecular biology
• Pharmacology: pharmacokinetics and pharmacodynamic modeling, drug discovery, etc.
• …and so many other disciplines within the life science space

As artificial intelligence continues to be adopted by organizations of all industries, it becomes more and more clear how significant this kind of technology is, particularly when applied to the life sciences research field and especially in the widespread pandemic like that caused by COVID-19. AI along with medical imaging is being harnessed in the fight against COVID-19 in diagnosis, treatment, and monitoring. With the help of artificial intelligence, researchers are also developing new tools that can help with early detection of the virus, plus personalized therapies for those infected.

HPC for Life Science: Cloud vs. On-Premise

While it’s safe to say that nearly all life science research organizations have adopted high performance computing as a means of managing their data, there’s still the argument of where to manage and store that data – through either on-premise or cloud computing resources. Some companies look into moving to the cloud in an effort to save on storage and processing costs, but what they’re not aware of is that the cost of storing data on the cloud gets more expensive as your data sets grow. Seeing how life sciences research organizations are forever learning and ingesting new data sets, it only makes sense that these scientific leaders are seeing their storage needs grow as well. With an on-premise data environment, data is stored at a fixed cost – the cost of the purchased system. There’s no sky high prices associated with accessing the very data that is already owned, something that cloud services can’t provide.

Other discrepancies between cloud providers and on-premise are those of security and reliability. With data stored in the cloud, everything is shared and no one, except the cloud service provider, owns anything. That means that the hardware, and physical resources inside of it like CPU cores, storage drives, and network interfaces storing your data are likely being shared by other organizations as well, organizations that could be direct competitors or even being investigated by government agencies due to questionable behavior.

In respect to reliability, storing data in the cloud means that organizations are at the mercy of their cloud provider. If that providers systems are down, there’s nothing to do but sit and wait through the restoration process. When data is stored on-premise in a data warehouse, any downtime would be rare, but more importantly, the hardware is physically accessible should any issues arise. Hardware providers also have dedicated support engineers to help address issues and minimize any downtime.

With the many scientific advancements that have come to light over the past few decades of widespread high performance computing in the life science space, it’s no secret that HPC will be the game-changing technology needed to solve our world’s health problems. We’re just here to make sure these organizations fighting on the frontlines have the tools and information they need to be successful, because a healthier world is one we all want to see.

Every month in the United States, 30 million mostly young users of the social media app TikTok spend an average of 46 minutes a day, viewing 37 billion videos. The app is one of the most downloaded apps in the world, exceeding monthly downloads of major apps like Youtube, Instagram, Facebook, and Snapchat.

Companies have been quick to realize the marketing potential of such a captive audience. Unfortunately, the app is getting attention for another reason. The Trump administration is considering a ban on the app. Why? TikTok is a Chinese video-sharing social networking service owned by ByteDance, a Beijing-based internet technology company. U.S. intelligence agencies believe the app may compromise user data. When asked about the app, Secretary of State Mike Pompeo said in an interview that people should only download the app “if you want your private information in the hands of the Chinese Communist Party.” Specifically, the U.S. alleges that the company could be compelled to “support and cooperate with intelligence work controlled by the Chinese Communist Party.”

The TikTok clamor comes on the heels of other U.S. efforts to block the use of technology developed in China on the grounds of national security. In 2019, U.S. President Donald Trump announced a ban on the use of telecom equipment from designated adversary states, including China. The ban was meant to “protect America from foreign adversaries who are actively and increasingly creating and exploiting vulnerabilities in information and communications technology infrastructure and services.”

While the order did not include specific companies or countries, it effectively applied to 5G telecom equipment providers Huawei and ZTE. At about the same time, the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce placed Huawei Technologies Co. Ltd. and its affiliates on the Bureau’s Entity List. Being on the list means such foreign-owned entities cannot use American technology.  

Concerns about backdoors into systems and other malicious activities are not unfounded. In October 2018, Bloomberg reported that some motherboards made by Supermicro had malicious components that were used to spy or interfere with the operation of the board. These motherboards were found on servers used by leading tech companies like Amazon and Apple, but Supermicro is certainly not the only company to manufacture components in China. Dell, HPE, Lenovo, and others have done so, and many still do.

U.S. Manufacturing is Key for Security

Many companies have manufactured products in China to cut costs. But are they doing so at the expense of compromised security?

PSSC Labs offers solutions for those who want a secure option. PSSC Labs is a U.S.-based company incorporated in California. PSSC Labs’ mission is to bring a superior level of service and support to a commodity-based industry.
