I've put up the fastest static binary for ARM in the binary section for people
to try out if they wish. On Android devices, I've just discovered that root is
not necessary to run userland programs.

I'm curious.

How did you get the pps value ?

Assume the following benchmark, what would be your computation ?

Render Time:
  Photon Time:      0 hours  0 minutes  2 seconds (2.600 seconds)
              using 15 thread(s) with 2.981 CPU-seconds total
  Radiosity Time:   No radiosity
  Trace Time:       0 hours  2 minutes 21 seconds (141.397 seconds)
              using 12 thread(s) with 1657.760 CPU-seconds total


icpc (ICC) 13.0.1 20121010, povray from master head at 9 June 2014.
i7 980X (6c/12t, 3.33 GHz):

-- 
IQ of crossposters with FU: 100 / (number of groups)
IQ of crossposters without FU: 100 / (1 + number of groups)
IQ of multiposters: 100 / ( (number of groups) * (number of groups))

based on the image output of the benchmark file, it's:

512*512/141.397=1853.96 pps

Does this mean I can install Povray on my LG G2? I wouldn't want to root  
it before the contract is over. I don't have a clue what to do with a  
tar.gz file.

You can, yes. The tar.gz file is a gzipped tar file. So you would need the tar
and gzip programs to uncompress it. Non-rooted phones don't generally have these
utilities. I'll upload another program into misc, busybox, that does encapsulate
all these utilities into one binary. Here's how you would use it:

1) make sure busybox and the tar.gz file are in the same directory
2) ./busybox tar zxf *tar.gz
3) Now you can run the povray benchmark as such: ./povray benchmark
4) Unfortunately, since your phone isn't rooted, you can't change the
clockspeed, so your phone's results will be low because it's thermally throttled
(which is something I found out recently).

BTW, rooting phones isn't all that difficult. Just follow the instructions. I
just bought my HTC One M8 yesterday, and it's already running a custom ROM. Your
LG G2 should be pretty easy to root (all known carriers):
http://forum.xda-developers.com/showthread.php?p=45692679#post45692679

To install Cyanogenmod:
http://wiki.cyanogenmod.org/w/Install_CM_for_d802

Also, it has been pointed out to me that the Snapdragon scores are low due to
thermal throttling. So I've rerun Povray using 1 thread and set clock speed at
about 1 GHz. Here are the results:

Snapdragon 801, MSM8974AC
  (1t, 0.96 GHz):                        35.34 pps ;  36.81 pps/GHz
S4 Pro APQ8064 (1t, 1.026 GHz):          31.58 pps ;  30.78 pps/GHz

D'oh! The site renamed busybox to busybox.dat. Also permissions aren't set
correctly. Anyway, after downloading busybox.dat do the following:

1) mv busybox.dat busbox
2) chmod 755 busybox

Now you can follow the remaining instructions.
