@IceTDrinker there may be an issue with MULTI_BIT_MESSAGE_3_CARRY_3 parameter sets. I'm trying to add tests on the multi-bit PBS with those parameters but they fail on CPU and GPU. cc @pdroalves

[IceTDrinker]

known issue, some of the algorithms needs power of 2 number of bits cc @tmontaigu he knows that better than me

[tmontaigu]

It looks like its core_crypto algorithms that fails not integer ones

[IceTDrinker]

yes my bad @tmontaigu Agnes told me that, we'll take a look this afternoon

[IceTDrinker]

ciphertext modulus log is wrong, we have 6 bits, here it has 8

I rebased this PR on the current main and it looks like the bug was fixed at some point between this PR and today. 3_3 core_crypto tests pass and I can run the primitives for polynomial_size=8192.

[IceTDrinker]

one of the issue was a wrong setting in the parameters, so maybe that fixed it

[pdroalves]

@agnesLeroy can we merge this one?
