That's one great script!

(In the example above, top host for pgrid is unexpectedly high.)

I have compared with GTX 1060 3GB

Project  |  Top 4 magnitude(s) for Nvidia GTX 1060 3GB|1

amicable  9.83   9.77   8.95   7.02
collatz   23.01  22.53  22.09  21.85
enigma    14.84  9.73   5.30   5.25
pgrid     23.49  23.18  19.68  18.12
einstein  18.19  17.09  15.36  15.17
milkyway  5.15   3.66   2.64   2.50
seti      22.81  14.30  12.18  11.89
gpug      19.54  19.44  19.15  18.69

And while for some projects like collatz or seti they (GTX 1060 3GB and GTX 1060 6GB) are almost equal, differences in other projects like enigma, amicable and milky are huge.
