If the order doesn't matter this is shorter:
a=666e666;b=666e666j;a+b;-_;_+a;-_;a-b;-_;_-b;-_;_-a

You can do something like
for i in $(seq 1 16); do
msieve -v -nc3 "dep_first=$i dep_last=$i" &
done
wait
and grep the factors from msieve.log.

I don't know. I have a 2060 Super that has 2176 shader units. Anything below 2176 curves takes as much time as 2176 curves. Total throughput is about 5-10% better for 4352 concurrent curves.
