Fiona: Accelerating FHE Inference with Packing-Aware Ternary Weights

Fully homomorphic encryption (FHE) enables neural network inference directly on encrypted inputs, but it remains orders of magnitude slower than plaintext in- ference. Applying the server's plaintext weights to encrypted activations involves plaintext-ciphertext multiplications (PMult) and accounts for more than half o...

The Unseen Delta: Characterizing the Compiler Optimization Landscape via Top-Down Differential Analysis

Compiler optimizations are essential for achieving high performance in modern software. However, recent studies highlight the persistence of performance bugs, i.e., subtle defects where the compiler generates functionally correct but computationally inefficient code, leading to significant performance degradation. Exis...
