HyperFoldUK/sparse-ternary-fma: Optimized High-Performance Ternary Arithmetic Kernel with 2-Bit Encoding and AVX-512 SIMD Acceleration for FHE and AI Applications

Unlocking the Future of AI with Efficient FHE

Fully Homomorphic Encryption (FHE) is poised to transform secure computing, yet significant performance bottlenecks have limited its adoption. Enter the sparse-ternary-fma kernel, a cutting-edge solution that enhances TFHE efficiency with remarkable innovations:

  • 2-Bit Ternary Encoding: Dramatically improves data density, packing 256 trits into a single 512-bit vector, yielding 4x-16x gains.
  • Sparse Processing: Optimizes processing by focusing on non-zero elements, offering speedups over 16x in typical key distributions.
  • SIMD Acceleration: Utilizes advanced AVX-512 architecture to enhance throughput by 2.38x.

Performance Proof: Benchmarks reveal substantial improvements in throughput and latency, paving the way for next-gen applications in AI and FHE.

This open-source kernel is not just a breakthrough but an invitation to collaborators. Join our mission at HyperFold Technologies to revolutionize AI and secure computing!
