Thanks. This looks like it requires CentOS, or am I mistaken? It also looks like nothing has been done with it since 2017. I'll study it a bit more.

Edit: It turned out to be an issue with the current revision of CADO-NFS, rather than the first time use of Registered memory.

I recently acquired a dual Xeon machine and "tried" to put it to work...

Script (calling YAFU wip r395):

do
printf "nextprime for $np is "
np=$(./yafu "nextprime($np)" -silent)
