On a somehow related note:

A friend of mine just had a bowel malignant tumour removed by surgery. The procedure went well, but he is now nicknamed semicolon.

As well as 6M.
Below 100M, there are currently 87 1M ranges with less than 20,000 to go, 12 between 20,000 and 20,499 and just one with 20,500 or more. Great progress.

I tried to allocate a bit less memory (11GB instead of 11.5) and that appears to have done the trick. At least stage 2 completed initialization successfully. Let´s see how it goes.

I have been really lucky, then. Never had a single issue since upgrading to 30.8b4 (just noticed I wrote b5 by mistake on my previous post). That improvement is referred in post #128 of this thread...

12.0 is getting close to finish. If it´s ok with everybody I would like to take 12.1 next.
@chalsall: if there is no objection, could you "release" it, please? Thx.

Why are you saying it switched from AVX-512 to FMA3 FFT?
As far as I can see, upon entering stage 2 it changed the length of the FFT (and as a consequence the value of B2) but not its type.

If you are using 22 out of 32 GB, which I think is the case, there is no reason (as far as memory is concerned) to experience all the symptoms you described. Funny.

Shall we leave the B1/B2 values in the worktodo file at B2 = 100*B1 so the program will choose the optimum figures for Stage 2, like in previous versions?

@chalsall,

I just started some tests on P-1 for the 12.00 - 12.05 M range. Could you please remove it from the available ranges?
Several results will be sent today, I hope.
Thank you.
