This document details the GPU performance benchmarks of programmable bootstrapping and keyswitch operations using TFHE-rs.

P-fail: $2^{-40}$

P-fail: $2^{-64}$

Reproducing TFHE-rs benchmarks

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

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

#PBS benchmarks:
make bench_pbs_gpu

#KS-PBS benchmarks:
make bench_ks_pbs_gpu

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

By their nature, homomorphic operations run slower than their cleartext equivalents.

• Integer operations

• Programmable Bootstrapping

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

The cryptographic parameters PARAM_GPU_MULTI_BIT_MESSAGE_2_CARRY_2_GROUP_3_KS_PBS were used.

1xH100

Below come the results for the execution on a single H100. The following table shows the performance when the inputs of the benchmarked operation are encrypted:

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

2xH100

Below come the results for the execution on two H100's. The following table shows the performance when the inputs of the benchmarked operation are encrypted:

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