AI continues to play a key position 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 programs develop in dimension and complexity, they’re changing into more durable 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 simple option to discover what occurred. Even when the info is offered, working with it takes coding, engineering abilities, and machine studying information that many scientists don’t have. The instruments are gradual, static, and laborious to adapt dynamically.
Scientists at Sandia Nationwide Laboratories are attempting 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 occurring inside a supercomputer utilizing plain language. As an alternative 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 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 have been aiming for extra than simply one other information device. They needed one thing that might really assist researchers ask questions and make sense of the solutions. As an alternative 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 via 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 approach that is sensible. Researchers can comply with system conduct, establish the place slowdowns occur, and spot patterns, all with no need to code or name in assist. EPIC helps make sophisticated infrastructure really feel extra comprehensible and fewer overwhelming.
To make that attainable, the group 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 information 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 business programs, they have been in a position to maintain efficiency excessive whereas lowering prices. The objective was to provide scientists a device that adapts to the best way they suppose and work, not one which forces them to be taught yet one more interface.
In testing, the system carried out effectively throughout a spread 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 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 completely different supercomputer workloads. Maybe most significantly, the platform delivered these outcomes with a fraction of the price and compute overhead sometimes anticipated from this setup. For researchers engaged on advanced programs with restricted assist, that sort of effectivity could make a big distinction.
“There’s an unmistakable hole between information and perception primarily bottlenecked by the complexity of dealing with massive 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 attainable when AI is woven straight into the analytics course of, and never simply an add-on. It may assist reshape how scientists work together with the instruments that energy their work. As fashions enhance and programs scale even additional, platforms like EPIC may assist be certain that understanding retains tempo with innovation.
