RE: 8-Queens Benchmark
8-Queens with Python on PRIME.
G1 : 0.047
G2 : 0.022

I copied the MicroPython code from Xerxes' benchmark list. Added only the timing procedure of module hpprime, and deleted the loop
Code:
from hpprime import * Time=eval("time") a = [0] * 9 r = 8 s = 0 x = 0 y = 0 t = 0 while True:  x += 1  a[x] = r  while True:    s += 1    y = x    while y>1:      y -= 1      t = a[x]-a[y]      if t==0 or x-y==abs(t):        y=0        a[x] -= 1        while a[x]==0:          x -= 1          a[x] -= 1    if y==1:      break;  if x==r:    break; Time=eval("time")-Time print(s) print(round(Time,6))
That is about 8 times faster than PPL on Prime: G2 ~0.166 times G1 ~0,38
