AI continues to play a key position in scientific analysis – not simply in driving new discoveries but in addition in how we perceive the instruments behind these discoveries. Excessive-performance computing has been on the coronary heart of main scientific breakthroughs for years. Nonetheless, as these programs develop in measurement and complexity, they’re changing into tougher to make sense of.
The restrictions are clear. Scientists can see what their simulations are doing, however usually can’t clarify why a job slowed down or failed with out warning. The machines generate mountains of system information, however most of it’s hidden behind dashboards made for IT groups, not researchers. There’s no straightforward approach to discover what occurred. Even when the information is obtainable, working with it takes coding, engineering expertise, and machine studying information that many scientists don’t have. The instruments are sluggish, static, and onerous to adapt dynamically.
Scientists at Sandia Nationwide Laboratories are attempting to alter that. They’ve constructed a system known as EPIC (Explainable Platform for Infrastructure and Compute) that serves as an AI-driven platform designed to reinforce operational information analytics. It leverages the brand new rising capabilities of GenAI foundational fashions into the context of HPC operational analytics.
Researchers can use EPIC to see what is going on inside a supercomputer utilizing plain language. As a substitute of digging via logs or writing advanced instructions, customers can ask easy questions and get clear solutions about how jobs ran or what slowed a simulation down.

“EPIC goals to reinforce numerous information pushed duties reminiscent of descriptive analytics and predictive analytics by automating the method of reasoning and interacting with high-dimensional multi-modal HPC operational information and synthesizing the outcomes into significant insights.”
The folks behind EPIC have been aiming for extra than simply one other information instrument. They wished one thing that may really assist researchers ask questions and make sense of the solutions. As a substitute of constructing a dashboard with knobs and graphs, they tried to design an expertise that felt extra pure. One thing nearer to a back-and-forth dialog than a command-line immediate. Researchers can keep centered on their line of inquiry with out leaping between interfaces or digging via logs.
What powers that have is AI working within the background. It attracts from many sources, reminiscent of log information, telemetry, and documentation. It brings them collectively in a manner that is sensible. Researchers can comply with system habits, determine the place slowdowns occur, and spot patterns, all while not having to code or name in help. EPIC helps make difficult infrastructure really feel extra comprehensible and fewer overwhelming.
To make that attainable, the crew behind EPIC developed a modular structure that hyperlinks general-purpose language fashions with smaller fashions educated particularly for HPC duties. This setup permits the system to deal with various kinds of information and generate a variety of outputs, from easy solutions to charts, predictions, or SQL queries.
By fine-tuning open fashions as a substitute of counting on large business programs, they have been in a position to hold efficiency excessive whereas decreasing prices. The aim was to provide scientists a instrument that adapts to the best way they assume and work, not one which forces them to be taught yet one more interface.
In testing, the system carried out properly throughout a variety of duties. Its routing engine might precisely direct inquiries to the best fashions, reaching an F1 rating of 0.77. Smaller fashions, reminiscent of Llama 3 8B variants, dealt with advanced duties like SQL era and system prediction extra successfully than bigger proprietary fashions.

EPIC’s forecasting instruments additionally proved dependable. It produced correct estimates for temperature, energy, and power use throughout totally different supercomputer workloads. Maybe most significantly, the platform delivered these outcomes with a fraction of the price and compute overhead usually anticipated from this setup. For researchers engaged on advanced programs with restricted help, that type of effectivity could make a big distinction.
“There may be an unmistakable hole between information and perception primarily bottlenecked by the complexity of dealing with massive quantities of knowledge from numerous sources whereas fulfilling multi-faceted use instances focusing on many alternative audiences,” emphasised the researchers.
Closing that final mile between uncooked system information and actual perception stays one of many greatest hurdles in high-performance computing. EPIC presents a glimpse at what’s attainable when AI is woven straight into the analytics course of, and never simply an add-on. It may possibly assist reshape how scientists work together with the instruments that energy their work. As fashions enhance and programs scale even additional, platforms like EPIC might assist be sure that understanding retains tempo with innovation.
