Dear,
On my laptop and my desktop, both “cat /proc/cpuinfo |grep processor|wc
-l” returning 4, and with 10 guixbuild users, I get these results.

Then, I run this tiny script fixing --max-jobs and --cores on my desktop
machine only:
--8<---------------cut here---------------start------------->8---
for npkg in 4 5 6 7 8 9 10 11 12
do
for JOBS in 1 2 3 4
do
for CORES in 1 2 4 8 16 32
do
echo "# num.of pkg=$npkg"
echo "# --max-jobs=$JOBS"
echo "# --cores=$CORES"
guix build --quiet --check -k \
--max-jobs=$JOBS \
--cores=$CORES \
$(guix package -A | head -n $npkg | cut -f1)
echo " "
sleep 2
done
done
done
--8<---------------cut here---------------end--------------->8---
And it hits the non-deterministic error for all the cases until the case
num.of pkg=11 --max-jobs=2 --cores=1 where it errors "all build users
are currently in use; consider creating additional users and adding them
to the `guixbuild' group".
Then npkg=11 --max-jobs=2 --cores=2 fails with non-deterministic.
(I reproduce on my laptop the result for npkg=11 max-jobs=2 cores=1,2.)
The next case, npkg=11 --max-jobs=2 --cores=4 does not seem reproducible
on my machine; similarly for cores=8,16,32.
Then I have not checked the reproducibility of the cases below.
Interestingly, npkg=11 --max-jobs=3 --cores=1,2,4,8,16 fails with not
enough builders. But not for --cores=32 which fails with
non-deterministic.
All the values for cores fails with not enough builder for npkg=11 and
--max-jobs=4.
Another surprise, npkg=12 --max-jobs=1 --cores=1,2,4,8,16,32 fails with
non-deterministic. And npkg=12 --max-jobs=2 --cores=2,4,8,16,32 too.
All the best,
simon
