World record (?) 10 Trillion iterations Mandelbrot zoom

Watch at the highest resolution you can!

Number of iterations at the furthest zoomed in minibrot: 10 T

The final frame calculation (1920x1080 resolution):
99% of the iterations are done with BLA steps of 1M or more
This program running on 6 x Raspberry Pi 4B@1.8GHz:
Time with PT and BLA: 1 hour 51 minutes
Estimated time without BLA: 9250 days
Estimated time without PT: 57000 years

Without PT: Regular MB-iters with MPFR - The Raspberry Pi 4B does about 21000 iterations/second on a single thread (using 7585 bits in the mantissa). The fewest iterations / pixel in the final image is 271045073999. The average iterations / pixel is 0.44*10^12, which results in a total of 9.1*10^17 iterations to be calculated, which corresponds to 1.8*10^12 seconds on 24 cores (6xRPI), i.e. 57000 years. Speedup of PT+BLA is about 270 million : 1!!

The reference point has 435252587 iterations, but has too many digits to write here.
