New GPU Kernel Speeds Up AI Retrieval Tasks, Cuts Memory Use

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Flash-MaxSim, a novel IO-aware fused GPU kernel designed to optimize late-interaction retrieval scoring. This new kernel computes the same scores as standard implementations but avoids materializing the large intermediate similarity tensor, significantly reducing memory usage and increasing speed. Flash-MaxSim achieves up to 3.9x faster performance on an A100 GPU and uses up to 16x less inference memory, enabling larger batch sizes and corpus sizes that were previously unachievable. AI

IMPACT Accelerates AI retrieval tasks by significantly reducing memory footprint and increasing processing speed.

    FLASH-MAXSIM: IO-Aware Fused Kernels for Late-Interaction Scoring

    Late-interaction retrieval (ColBERT, ColPali) scores a query against a document with the MaxSim operator: for every query token, the maximum similarity over the document tokens, summed over query tokens. The standard implementation materializes the full query-token x document-tok…
