Researchers have developed FlashSinkhorn, a new GPU-accelerated solver for entropic optimal transport (EOT) that significantly reduces memory input/output operations. By rewriting stabilized log-domain Sinkhorn updates to mimic the normalization process in transformer attention, FlashSinkhorn enables fused kernels that stream data through on-chip SRAM. This approach achieves substantial speedups, up to 32x for forward passes and 161x end-to-end, compared to existing methods on A100 GPUs for tasks like point-cloud OT. AI
