Thank you very much!

Why does c1032.job.T1 contain:

Code:
print OUTF "m: $M\n" if ($M); Code:
print OUTF "n: $N\nm: $M\n";

It was an inexact translation of #defines like this to AVX512 in lasieve_prepn: #define A1MOD0(p) ((aux= absa1%p)> 0 ? paux : 0 ) where I neglected to account for the "else" case (where absa1%p == 0)

lpb34 crash
When sieve R942 using lpb34, the avx512lasieve5 crash immediately,
while the original lasieve5 could work properly. command is ./gnfslasieve4I16e v f 380000000 c 1000 o R942_16e_r_380000000_380001000.out r R942_poly.txt R R942_poly.txt file attached.

Thanks for the fix.
Another confusion is that , when set the rlim and alim to 500000000, the version 551 (newest version) is about 10% slower than the 550 version (second newest version). I'm not sure if change the _mm512_set1_epi32(ij_ub) to _mm512_set1_epu32(ij_ub) or such modification could resolve the slower speed.
