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_MESSAGE_2_CARRY_2_GROUP_3_KS_PBS were used.
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:
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:
TFHE-rs benchmarks can be easily reproduced from the source.
The following example shows how to reproduce TFHE-rs benchmarks:
