AI continues to play a key function in scientific analysis – not simply in driving new discoveries but additionally 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 methods develop in dimension and complexity, they’re changing into tougher to make sense of.
The restrictions are clear. Scientists can see what their simulations are doing, however typically can’t clarify why a job slowed down or failed with out warning. The machines generate mountains of system knowledge, however most of it’s hidden behind dashboards made for IT groups, not researchers. There’s no simple option to discover what occurred. Even when the info is offered, working with it takes coding, engineering abilities, and machine studying data that many scientists don’t have. The instruments are gradual, static, and exhausting to adapt dynamically.
Scientists at Sandia Nationwide Laboratories are attempting to vary 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 knowledge 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 means of 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 knowledge pushed duties comparable to descriptive analytics and predictive analytics by automating the method of reasoning and interacting with high-dimensional multi-modal HPC operational knowledge and synthesizing the outcomes into significant insights.”
The individuals behind EPIC had been aiming for extra than simply one other knowledge software. They wished one thing that might 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 targeted on their line of inquiry with out leaping between interfaces or digging by means of logs.
What powers that have is AI working within the background. It attracts from many sources, comparable to log recordsdata, telemetry, and documentation. It brings them collectively in a means that is sensible. Researchers can observe system habits, determine the place slowdowns occur, and spot patterns, all without having to code or name in assist. EPIC helps make sophisticated infrastructure really feel extra comprehensible and fewer overwhelming.
To make that potential, the workforce behind EPIC developed a modular structure that hyperlinks general-purpose language fashions with smaller fashions skilled particularly for HPC duties. This setup permits the system to deal with various kinds of knowledge and generate a spread of outputs, from easy solutions to charts, predictions, or SQL queries.
By fine-tuning open fashions as an alternative of counting on large industrial methods, they had been capable of preserve efficiency excessive whereas lowering prices. The purpose was to offer scientists a software 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 spread of duties. Its routing engine may precisely direct inquiries to the best fashions, reaching an F1 rating of 0.77. Smaller fashions, comparable to 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 vitality use throughout completely 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 methods with restricted assist, that sort of effectivity could make a big distinction.
“There’s an unmistakable hole between knowledge and perception primarily bottlenecked by the complexity of dealing with giant quantities of information from numerous sources whereas fulfilling multi-faceted use circumstances concentrating on many various audiences,” emphasised the researchers.
Closing that final mile between uncooked system knowledge and actual perception stays one of many greatest hurdles in high-performance computing. EPIC affords a glimpse at what’s potential when AI is woven immediately 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 methods scale even additional, platforms like EPIC may assist be certain that understanding retains tempo with innovation.
