E2Former-V2: On-the-Fly Equivariant Attention with Linear Activation Memory
E2Former-V2 introduces a scalable architecture integrating algebraic sparsity and hardware-aware execution to address critical scalability bottlenecks in Equivariant Graph Neural Networks (EGNNs) for 3D atomistic systems. By proposing Equivariant Axis-Aligned Sparsification (EAAS) and On-the-Fly Equivariant Attention, it transforms computationally expensive dense tensor contractions into efficient sparse operations. This fully node-centric mechanism, implemented via a custom fused Triton kernel, achieves a 20x improvement in TFLOPS and maintains comparable predictive performance while notably accelerating inference on large molecular datasets like SPICE and OMol25, demonstrating efficient training on accessible GPU platforms.

Scalability Breakthrough: 20x Inference Speedup
20x Inference AccelerationE2Former-V2 fundamentally re-engineers equivariant graph neural networks, moving from edge-centric to a fully node-centric architecture. This shift, combined with hardware-aware kernel optimizations, enables on-the-fly computation, eliminating costly edge-level intermediate tensors. The result is a dramatic increase in processing throughput and a significant reduction in memory footprint, achieving up to 20x faster inference compared to traditional methods, especially for large molecular systems.
Optimizing Tensor Products: The EAAS Workflow
Equivariant Axis-Aligned Sparsification (EAAS) is a novel algebraic reduction technique that transforms dense SO(3) tensor products into sparse, permutation-based operations. By exploiting an SO(3) to SO(2) change of basis and aligning features to a local axis, EAAS achieves a significant reduction in arithmetic complexity and memory footprint, resulting in a ~6x speedup during the critical convolution stage.
