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...

When sieve R942 using lpb34, the avx512-lasieve5 crash immediately,

while 315M to 316M collect 1291314 relations, about 331646 less relations.

I think it is, this source needs cweb command, perhaps it means command ctangle should could run normally.

I could build that source 5 years ago, but it is a little strange that now I cann't...

1. Validity check.
For safety reason, I write a small program and
have verified that for the small test relation set (R1340L, q=316M, -c 1000),
the avx512 ggnfs version's relations are all belong...

The new binary seems a bit faster again, but relations sieved still less than official ggnfs.

My computer's CPU is Intel Core i5-1135G7, the /proc/cpuinfo says it support avx512.

After I install icc , I could compile a gnfs-lasieve4I16e binary successfully,
but a little slower (0.75062...

When I try your gnfs-lasieve4I16e on number R1340L (an degree 8 snfs) near q=316M, the speed
is 0.73 sec/rel, while the original binary is 0.96 sec/rel.

So I try to compile a Linux or a Windows...
