I am wondering if there is a way to use “concrete-fft” and “avx512” options as in TFHE-rs benchmark.
Or are they default options?
I am asking because of the huge gap between the benchmark and the reported run-time (~100 times slower) on my machine (Intel Xeon Silver 4114 CPU 2.20GHz).
I think the gap is way larger than the gap between the machines.
By the way, I am looking at the paper Parameter Optimization & Larger Precision for (T)FHE, but cannot find the optimized parameters in the recent release (and in git repo) of TFHE-rs. Are you going to put those parameters into TFHE-rs? I have lots of interest in large integer LUTs.
The parameter sets of the paper are not directly given in the THFE-rs release because we prefer ensuring a lower error probability (1/2^40) with the lib (whereas in the paper, the error is bounded by 1/2^13.9). However, you can easily change the parameters by hand, to put the ones from the paper instead!
Note that the current parameter sets associated to the WoPBS needs to be clean up . We are working on this, so next releases might be helpful to you
