AI continues to play a key function 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 techniques develop in dimension and complexity, they’re changing into tougher to make sense of.
The constraints 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 solution to discover what occurred. Even when the info is obtainable, working with it takes coding, engineering expertise, and machine studying data that many scientists don’t have. The instruments are gradual, static, and laborious to adapt dynamically.
Scientists at Sandia Nationwide Laboratories try to alter that. They’ve constructed a system referred to 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 by way of logs or writing complicated instructions, customers can ask easy questions and get clear solutions about how jobs ran or what slowed a simulation down.

“EPIC goals to reinforce varied information pushed duties comparable to 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 had been aiming for extra than simply one other information instrument. They needed one thing that may truly 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 targeted on their line of inquiry with out leaping between interfaces or digging by way of logs.
What powers that have is AI working within the background. It attracts from many sources, comparable to log information, telemetry, and documentation. It brings them collectively in a method that is sensible. Researchers can observe system habits, establish 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 doable, the workforce 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 huge business techniques, they had been in a position to preserve efficiency excessive whereas decreasing prices. The aim was to present scientists a instrument that adapts to the way in which they assume and work, not one which forces them to study yet one more interface.
In testing, the system carried out nicely throughout a variety of duties. Its routing engine may precisely direct inquiries to the suitable fashions, reaching an F1 rating of 0.77. Smaller fashions, comparable to Llama 3 8B variants, dealt with complicated 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 vitality use throughout totally different supercomputer workloads. Maybe most significantly, the platform delivered these outcomes with a fraction of the associated fee and compute overhead sometimes anticipated from this setup. For researchers engaged on complicated techniques with restricted help, that form of effectivity could make a major distinction.
“There’s an unmistakable hole between information and perception primarily bottlenecked by the complexity of dealing with giant quantities of information from varied sources whereas fulfilling multi-faceted use instances concentrating on many various 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 doable when AI is woven instantly into the analytics course of, and never simply an add-on. It could assist reshape how scientists work together with the instruments that energy their work. As fashions enhance and techniques scale even additional, platforms like EPIC may assist be certain that understanding retains tempo with innovation.
