So, does this mean that p=M31 has all the required roots-of-two for the IBDWT for Z/pZ NTT? so, is NTT(M31) a viable alternative to FGT?
Or, the problem with M31 is that it doesn't have the...

The need for the general-MUL vs. MUL-3 only appears when changing the "L" step dinamically during a test. This is something GpuOwl does not support (and thus gets away with using MUL-3), but prime95...

I recently got a Radeon VII with Samsung memory (as as RMA replacement). Even without any RAM overclock, and without any undervolt, that memory consistently generates errors. This is in contrast with...

3xSP sum()
Unfortunately the sum() I have up to now is a beast: 54 ADDs.
This seems a rather very expensive sum()..
To see some corner-cases that sum() must handle, here is one example: given "x", we'd...

Figure 10 seems to indicate:
c0,e0 = twoSum(a0, b0)
d1,e11 = twoSum(a1, b1)
c1,e12 = twoSum(d1, e0)
c2 = a2 + b2 + e11 + e12
which looks pretty good (i.e. simpler than I was expecting)

SP plan
I've been thinking some more about a practical SP FFT implementation on GPUs, and here are some problems/ideas:
1. FFT twiddles, i.e. the trigonometric constants (sin+cos) used in the FFT.

The cache (L1/L2/L3) is used transparently for the *global* memory operations. It is managed automatically by the cache control (probably a variant of LRU), not explicitly by the software. So yes,...
