Integer

This document details the GPU performance benchmarks of homomorphic operations on integers using TFHE-rs.

All GPU benchmarks were launched on H100 GPUs, and rely on the multithreaded PBS algorithm.

The cryptographic parameters PARAM_GPU_MULTI_BIT_GROUP_4_MESSAGE_2_CARRY_2_KS_PBS were used.

Pfail: $2^{-128}$

8xH100-SXM5

Below come the results for the execution on eight H100 using SXM technology. The following tables show the performance when the inputs of the benchmarked operation are encrypted:

Encrypted/encrypted operations latency

Encrypted/encrypted operations throughput

The following tables show the performance when the left input of the benchmarked operation is encrypted and the other is a clear scalar of the same size:

Encrypted/clear operations latency

Encrypted/clear operations throughput

Reproducing TFHE-rs benchmarks

TFHE-rs benchmarks can be easily reproduced from the source.

The following example shows how to reproduce TFHE-rs benchmarks:
